The Future of Pipeline Coating Technology




Having worked at Dow Chemical for over two decades, I have observed firsthand the evolution of pipeline coating technologies. These coatings protect pipelines from corrosion, temperature fluctuations, and chemical exposure. Over time, advancements in materials science have transformed this field, and the pace of innovation continues as we look toward the future.

In the present, the most common types of pipeline coatings include fusion-bonded epoxy (FBE), polyurethane, and polyurea coatings. Each of these materials offers distinct advantages depending on the application. FBE has been widely used for decades due to its strong adhesion properties and high resistance to corrosive environments. It remains a popular choice for oil and gas pipelines. However, one of its limitations is its lack of flexibility, making it more prone to cracking when pipelines are subjected to significant temperature variations or ground movements.

Polyurethane coatings have gained traction due to their higher flexibility compared to FBE. They are able to withstand moderate movement and thermal expansion, making them suitable for pipelines in areas with more variable environmental conditions. Polyurethane’s ability to form a strong, continuous barrier also makes it an excellent choice for both external and internal applications. Despite its benefits, polyurethane coatings tend to have longer curing times, which can slow down pipeline installation and rehabilitation projects.

Polyurea is where we see some of the most exciting developments in the field. Polyurea coatings offer rapid curing times, allowing pipelines to be returned to service more quickly. This material’s flexibility is unparalleled, enabling it to stretch and contract with the pipeline as needed, while still maintaining its protective qualities. Its resistance to chemicals, abrasions, and temperature extremes makes it a versatile solution for a range of pipeline applications. What sets polyurea apart from other coating materials is its ability to form a seamless, waterproof barrier, which is particularly valuable in underwater or highly corrosive environments. I have worked extensively with polyurea during my time at Dow Chemical, and its combination of speed and durability represents a major step forward in coating technology.

Looking to the future, we are already seeing the development of hybrid coatings that combine the best attributes of multiple materials. One of the trends in pipeline coating technology is the use of nanomaterials to enhance the properties of existing coatings. These nanoscale additives improve the overall performance of traditional coatings by increasing their resistance to corrosion, abrasion, and UV radiation. For example, graphene-enhanced coatings are being explored for their potential to dramatically improve the strength and durability of pipeline coatings without adding significant weight or bulk. The inclusion of these materials may lead to coatings that not only last longer but also require less maintenance over the pipeline’s operational life.

Another exciting area of research is the development of self-healing coatings. The concept behind self-healing technology is that the coating can repair itself when damaged, thereby extending the pipeline’s protection and reducing the need for frequent maintenance or repairs. Some of the initial research in this area focuses on incorporating microcapsules within the coating that contain healing agents. When the coating is scratched or cracked, these capsules break open, releasing the healing agent and automatically repairing the damage. Although still in its early stages, self-healing coatings could revolutionize the way we approach pipeline protection.

As we move into the future, sustainability will also play a critical role in shaping the development of pipeline coatings. Current coating materials often rely on petrochemicals, which contribute to environmental degradation. The industry is now looking at greener alternatives, including bio-based polymers and coatings with lower volatile organic compound (VOC) emissions. The challenge lies in developing materials that provide the same level of protection and durability while minimizing their environmental footprint. Some of my recent research has focused on identifying eco-friendly coating solutions that don’t compromise performance, and I believe we are on the cusp of breakthroughs in this area.

The future of pipeline coating technology is bright, with many promising innovations on the horizon. However, it’s important to remember that the effectiveness of any coating depends on proper application and surface preparation. Even the most advanced materials will fail if applied incorrectly. That’s why continued research into application techniques, including the use of robotics and automation for consistent coating application, will be just as important as the development of new coating materials.

In conclusion, the pipeline industry is set to benefit greatly from advancements in coating technology. From polyurea’s fast curing times and flexibility to emerging innovations like nanomaterials and self-healing coatings, we are seeing significant improvements that will help protect our infrastructure for decades to come. My work at Dow Chemical has shown me the transformative potential of these materials, and I am excited to see how they continue to evolve in the future.

Innovative Pipeline Rehabilitation Techniques: Ensuring Long-Term Integrity

 





The infrastructure of pipelines plays a role in transporting oil, gas, and water efficiently over long distances. However, as pipelines get older, they are more susceptible to problems, like corrosion and leaks. Diminished structural strength. Pipeline maintenance approaches have undergone significant advancements to keep them operational and avoid breakdowns. These techniques are designed to bring pipelines to their best working state without requiring complete replacements, which helps minimize downtime and saves valuable resources in time and money. It's crucial to grasp these rehab methods to maintain the durability of pipeline systems in the run. 


One of the common methods for pipeline rehabilitation involves using protective coatings is applying protective coatings. Polyureathane has become popular as a solution for pipeline rehabilitation because of its strong wear and tear resistance and ability to form a seamless protective barrier. The unique characteristics of polyureathane enable it to adhere to the pipe surface, shielding it from external factors like water, chemicals and temperature changes. This approach is especially efficient, in averting corrosion a factor contributing to pipeline failures. Polyureas are quite reliable as they do not crack or degrade easily under pressure like some coatings do; hence they help prolong the pipeline's lifespan. 


An used method in pipeline repair is slip lining where a new pipe, with a smaller diameter is inserted into the current pipeline to replace the damaged section structurally.This approach works well for pipelines that have undergone wear and tear but are still strong enough to handle the addition of a new liner.Slip lining fixes leaks or fractures and strengthens the pipelines structure while maintaining its ability to transport materials effectively. There are benefits to slip lining as it enables the rehabilitation of pipelines without requiring significant excavation work and reduces disturbance to nearby areas. 


The use of cured-in-place pipe lining (known as CIPP) has become increasingly popular as a method for rehabilitating pipelines in recent times. In CIPP operations, a flexible liner coated with resin is inserted into the impaired pipe. Inflated to ensure the resin adheres to the inner surface of the pipeline. Subsequently applying heat or UV light helps solidify the resin and create a new inner pipe that bolsters the original pipeline structure. This technique offers a fix that stops leaks and lowers the chances of potential harm down the line.Cured in place pipe (CIPP) proves handy when digging is hard or pricey since the entire procedure takes place inside the pipe itself. 


Many conversations about methods to repair pipelines often overlook the step of conducting thorough inspections and assessments before implementing any rehabilitation technique. Thoroughly pinpointing the location and characteristics of the damage is essential for selecting the appropriate course of action. Utilizing tools like pipeline inspection gauges (PIGs) and advanced imaging devices enables technicians to assess the pipeline's state in real-time by obtaining data on corrosion levels or any cracks or flaws present within it. To identify areas needing repair and choose the method, for pipeline rehabilitation engineers can rely on these tools to address the unique challenges faced. 


Polyurethane coatings, along with slip lining and CIPP methods, are utilized to prolong the lifespan of pipelines with a focus on conditions in mind. An instance of this is using polyurethane for pipelines located in weather conditions due, to its ability to withstand UV rays and extreme temperatures while repelling moisture. Nonetheless, it is crucial to prepare the surface before coating application since inadequate preparation may result in adhesion problems. In this way, accurate measurements and careful planning are vital for slip lining and CIPP to guarantee that the new liners fit snugly in the current pipeline, creating a secure seal without compromising the flow capacity. 


Spray applied pipe linings (SAP Lining) alongside the methods discussed earlier mentioned before that are being embraced in the industry as a means to address pipelines with diameters or unconventional shapes.SAP Lining entails applying a polymer based substance like polyurethane onto the inside of the pipeline.This approach offers a protective layer that sticks to the surface and hinders any further deterioration.SAP Lining proves efficient in scenarios where conventional repair methods are not feasible due, to the pipelines size or intricacy. By creating a shield along the pipeline route, SAP extends the pipeline's lifespan and lowers the chances of future harm. 


Many folks tend to forget about the importance of monitoring and upkeep following pipeline rehabilitation efforts – even the cutting-edge methods can't ensure lasting protection without proper maintenance in place! Regular checks play a role in spotting potential problems early on and addressing them swiftly before they turn into bigger headaches, down the line. Fiber optic sensors are now commonly utilized to monitor the condition of pipelines, in real time to ensure they function effectively in the long term. 


To summarize the discussion on pipeline restoration advancements, the industry is changing as new methods emerge to improve the efficiency and efficacy of maintaining pipeline integrity. Polyurethane coatings and slip lining are, among the techniques that enable pipeline repair without necessitating complete replacement. Through the adoption of these strategies, operators are able to prolong the lifespan of their infrastructure, cut down on expenses, and mitigate disruptions effectively. Achieving rehabilitation necessitates thorough planning and precise evaluation with consistent upkeep to guarantee the sustained effectiveness of these approaches in the long run.With advancements in the field ongoing the outlook for pipeline rehabilitation appears promising with the potential, for sophisticated methods that provide increased resilience and safeguarding for vital infrastructure assets.

The Growing Disconnect in the Pipe Coating Industry



Takeaway: The continued growth of the pipe coating market needs and relies upon successfully bridging the current disconnect and interacting to deliver quality used coatings.


A Historical Perspective of Pipeline Coatings

  • Pipeline Coatings in today's Day
  • Ideas to Address the Industry Disconnect

In the last twenty or thirty years, the oil and gas pipeline coatings market has seen many modifications. From the days of coal tar coatings with fairly little oversight, the fast growth of sophisticated coatings, particularly fusion-bond epoxy (FBE) with really specific application procedures, has led to highly comprehensive coating specs covering every element of the process. For example, coating specs when I started in the late 1990s were possibly four or five pages in total. It is common to see 35 to even 75-page specifications, depending upon the job and scope.


With recent increased state and federal guidelines such as the Pipes Act of 2016 and the general public's increased awareness of pipelines as supplied by the media, end-users and engineers have been pressured to increase their knowledge and control pipe coating application. This has resulted in an ever-expanding level of specifications, standards, and detailed processes. The level of evaluation, and the comprehension of coatings inspectors, has also seen incredible development, with training programs such as those from NACE and SSPC (now merged as AMPP).


Regrettably, the disadvantage of this trend is that it has failed to reach the ground-level plant workers charged with surface area preparation, using the coatings and final inspection, and those responsible for reading and translating these specifications work-floor guidelines are established. The starts of the detach between the segments were indisputable and mostly unavoidable.



A Historical Perspective of Pipeline Coatings

The pioneering days of applied coatings are long over. But even in the early stages of modern pipe coating, "The typical plant worker typically had a high school education and was not always a graduate. However it was very uncommon that any had college experience at all," kept in mind Steve Garcia, the current owner of Deep South Quality Inspection and a former coating plant supervisor of 25-plus years. Garcia included, "That consisted of everybody from the ground up."


Training programs at the time were almost non-existent, and the majority of them any training was on-the-job training utilizing knowledge by far through generations of coaters. "But much of the [senior] coaters with the most experience hesitated to share their understanding," included Garcia. Fundamental job security concerns, while understandable, led to unfavorable impacts on the growing coatings industry by creating unintentional classes of plant employees, and in many cases, in supervisory and management levels too.


The engineering teams concentrated on the operational elements of pipelines for the end-users, leaving much of the coating manages to the applicators and powder coating producers. As in the plant settings, the event and transfer of understanding on the engineering side were kept within a narrow group. 


A resulting negative was "the growing space between the two sectors and the tension, if you will, between coaters and end-users," according to Mark Greenly, now a General Manager for Womble Coating.


"The sides were running completely different from each other yet attempting to reach the very same objective," Greenly stated.


Coating operators were not communicating their practical worry about the engineers, and the engineers were hardly ever experienced in the coating application at the plant level. As such, the beginnings of an internal detachment within the market were self-initiated.




Pipeline Coatings in today's Day.

In the existing industry setting, the detach between these two sectors is still present for many reasons, however, arising from various scenarios.


As previously pointed out, increased governmental and environmental participation in pipelines has forced end-users to broaden their engineering departments to conform to the broadening guidelines. The inevitable result is high-level specifications, with high-level language planned to deal with these changes, but still with really little useful knowledge of the coating application plant operations. On the plant side, regrettably, there has been very little modification in the labor force demographics, which leaves them at a great disadvantage and primed for an even higher divide.


In fact, "it is common for plant workers to hold bitterness towards engineers for their absence of real-world application constraints and production practices," stated Garcia, and vice versa for engineers to be frustrated at the coaters' lack of knowledge of regulative requirements.


A clear example of just how far the two sides have ended up being even further separated is the difference in typical wage for coating engineers and coating plant employees. However, a difference is certainly warranted as engineering degrees can cost upwards of $50,000 annually. According to current numbers, coatings engineers balance $93,000 per year in the US, whereas ground-level labor earns an average of $13.75 per hour in the United States. Which hourly price quote for plant labor may even be slightly elevated from today's actual coating plant employees' wages, considering staff turnover rates in coating plants, which leads to a greater number of entry-level wages.


This also decreases the general and particular understanding of plant workers, where employers hesitate to purchase substantial training only to have the employees seek greater wages (a benefit of the offered training) in other places, however then leaving the companies needing to start over with the next batch of freshly-hired employees constantly.


There has been a shift lately for coating applicators to work with supervisors and plant supervisors with college levels. But without hands-on coating experience and the ability to relate directions directly with the work crews, this may add to the expanding detach between the plant workers, experienced coaters, and end-users.


Nevertheless, even with well-qualified plant supervisors and supervisory staff, the growing requirement for third-party inspectors to be onsite and serving as an agent of the end-user puts a possibly unintended block on open interaction between the completion user and the coating applicators. By and large, inspectors are not mediators on behalf of completion users; however, they are witnesses and enforcers of the requirements as written, often without appropriate standardized practices. Regrettably, inspectors, even those accredited by acknowledged training programs such as NACE's CIP program, can likewise do not have a useful working understanding, which further exacerbates the divide.


Bridging these spaces between each of the sections above-- end-users and coating engineers, coating applicators, and third-party representation-- is an extensively looked-for objective throughout the market, as is evidenced by the growing interest and subscription in organizations such as AMPP. (Related reading: 9 Ways the Merger Between NACE and SSPC Will Impact Corrosion Pros.) However, reaching any unified objective in a multi-entity market needs the recognition and effort to discover a starting point attending to the issues.


Recommendations to Address the Industry Disconnect.

Based upon recommendations from Garcia and Greenly, my own experiences with each facet of the industry, and general scuttlebutt within various coating centers, the following are some specific suggestions to begin narrowing the divide:


End users and engineers charged with composing requirements would take advantage of seizing the Day to hang around in a functional coating plant, not only to get experience in the application procedure itself, however more notably to understand the proper operations and practical and economic restrictions faced by coating plant operators. Experiencing the coater's perspective first-hand might assist in comprehending a coater's reluctance to continuously change plant criteria, especially those that have no impact on coating integrity, mainly based upon efficiency and lowering operating expense always on an objection to satisfy consumer expectations. This is particularly real with small quantities where several changes can cost countless dollars in downtime.

A popular recommendation for firms that accredit inspectors is to institute apprentice-level accreditations that need a minimum number of hours with a qualified inspector before advancing to full certification. Another possibility is to include specific market recommendations that supplement basic knowledge accreditations to ensure practical experience as end-user agents.

Coating applicators must understand that policies increase and intensify and the pressure and enforcement action being directed at the end-users. Buying the education and official training of mid-to upper-level personnel not only provides a benefit to the coating market in general, however likewise leads to more efficient operations by minimizing turnover. (For some training ideas, read about some Ways to Maintain or Update Technical Skills.).

The continued development of the pipe coating market requires and relies upon successfully bridging the current detach and collaborating to provide quality applied coatings, offer safe and efficient pipelines, and fulfill full regulatory compliance. It will require the cooperation and effort of all celebrations. However, we will all be much better at it.

 







 

 

Polyurea Pipelining





Polyurea will surpass paint and epoxy coatings whilst decreasing your ongoing maintenance costs when utilized on pipelines, it also complements insulated pipelines when used over polyurethane foam. New pipelines are frequently coated in the factory and areas just left uncoated for the welding procedure. These areas are the now worst exposed locations not only as they are coated in the field using epoxy systems but the welding procedure alters the pipeline's material structure making it more susceptible to corrosions and other flaws.

Coating your pipeline externally with polyurea will offer several years of protection from the environment and external conditions, when coated internally the pipeline's life can be extended much further than initially believed. Having corrosion on your pipeline will eventually result in leaking systems which can trigger damage to persons and the environment. Current epoxy systems are field applied systems that are simple to apply but have a high failure rate.

With an estimated 800,000 miles of leaking and shabby pipelines in America, it reveals what a poor state the United States facilities is presently in.

Kinds of pipeline coatings might consist of Polyethylene, HDPE, HDPP (high-density polypropylene), 3 layer polyethylene, polymer coatings, epoxy coating and polyurea coatings.

Pipeline Lining & Coating Systems
Polyurea can be applied to pipeline internals by way of a spray robot, this robotic flights the internal of the pipelines whilst applying polyurea utilizing a rotary head. This technique offers excellent protection and an excellent long last, hard-wearing internal lining system for your piping. One excellent advantage of this system in the pipeline can be left in place so doesn't need to be collected to carry out this lining process.

It's approximated that the US will need to find over $1 trillion to fix the buried potable water line that will fail due to deterioration. Polyurea lining systems can be used on pipes as little as 1 inch in diameter and because this technology is referred to as trenchless the benefits to the environment and lower costs are significant.


Why Choose Trenchless
Trenchless lining systems have numerous advantages over trenched, cost ramifications and environmental effects are 2 of the primary. Polyurea systems can be utilized on virtually all pipelines from concrete to steel and are an exceptional choice for pipeline rehabilitation.








 

9 Questions To Find The Correct Protective Coating for Your Pipeline






No special coating can protect every pipeline from corrosion in all situations. Finding a suitable coating for each application can be challenging. But asking the best questions can help you find the product offering the best long-term performance.


To distinguish a coating for the job, understanding the project requirements and performance needs are key parts of the process. Here is a list of questions you should ask:


  1. Atmospheric condition: Is the application above or below ground?
    1. If above ground, will the coating be exposed to UV?
    2. If buried, what is the state of the soils or backfill? How soon will the pipeline be backfilled?
    3. Condition of the substrate or the existing coating. Which surface are preparations adequate methods? Is the existing coating well-bonded, and will it accept succeeding coatings?
    4. Are there limitations to which surface preparation methods, such as sandblasting or grinding, are allowed at the site?
    5. Is the pipe dry, or can it be dried?
  2. What is the width of the pipe?
  3. What is the service temperature of the pipe?
  4. What are the environmental conditions that will be present during the administration?
    1. temperature
    2. relative humidity
    3. Other?
  5. Are there abnormal shapes or details (flanges, tees) in the pipe?
  6. Is there an atmospheric “transition” area from below to above ground? Is additional mechanical protection required for protection at the freeze/thaw line?
  7. Is protection required from lawnmowers, string trimmers, and the like?
  8. Will the coating be employed by maintenance staff or a professional coating applicator?




The responses to these questions should be evaluated to determine the proper coating for the application.
