Pipe Coating Solutions

TDC International’s (TDC) GRP pipe protection system, pau wrap®, is an extremely resilient composite of thermosetting material, consisting of unsaturated polyester resin and high-quality textile glass fibres.

The GRP pipe protection system pau wrap® is designed to provide an additional protective measure against indentation, scratching, tearing, chemicals, sharp rocks, other abrasive conditions and harsh geological conditions.

TDC’s pipeline coating products not only provide high quality, reliable protection to pipelines during the construction phase but also during its lifespan. pau wrap® helps pipeline owners to meet exceedingly stringent environmental requirements whilst extending the life of the pipeline.

Our coating products have been used for pipelines transporting oil, gas, various chemicals, refined petroleum products, water and wastewater.

For the anti-corrosion protection layer for both line pipe coating as well as field joint coating, we offer a full range of options, which we have continuously developed and proven over the years. These include:

  • Polyethylene (PE)
  • Polypropylene (PP)
  • Polyurethane (PU)
  • Fusion bonded epoxy (FBE)

Every corrosion-protection product is fully tested and certified in accordance with our Quality Management System prior to application.

Line Pipe Coating

TDC’s trenchless application pau wrap® TL offers extreme protection to abrasion, corrosion, temperature, physical force and chemicals, can withstand harsh underground geological conditions, and are especially suitable for hard rock formations, such as granite, gravel, quartzite, etc.

Specifically designed for the trenchless pipeline construction, pau wrap® TL as well as various tailored customer applications, have been successfully used across all typical trenchless installation methods. For example, during horizontal directional drilling, direct pipe or micro-tunnelling projects. No matter the circumstance, pau wrap® TL offers a robust mechanical protection system for the installation and construction process of pipelines.

TDC has developed an open trench application pau wrap® OT, which combines the highest mechanical protection properties with the light weight and ease of handling and installation that is customary to the pau wrap® system. Whether used as protection from rough trench backfill or above-surface from rock fall, pau wrap® OT is tailored towards the specific project needs for mechanical protection.

Field Joint Coating

TDC offers the complete coating solution for pipe coatings including welding seam coating at the job site by the TDC team or TDC certified contractors. The section where two pipes meet and are welded together is the welding joint (also known as the field joint). Especially during the horizontal directional drilling (HDD) process, or with other trenchless pipeline installation methods, the field joint is often the most vulnerable part in any pipeline installation and is likely the most easily overlooked aspect of the total coating system.

TDC’s integrated pipe coating system approach, pau wrap®, enables a homogenous outer coating of consistently high mechanical resistance and can be considered as an anti-abrasion layer to protect both the underlying steel, as well as the anti-corrosion coating layer. The pau wrap® product range provides the same performance for the pipe as for the field joints.

The uniquely developed pau wrap® field joint coating materials can provide a robust, reliable protection, irrespective of the factory pipe coating. It works best with a homogeneous application using our pau wrap® factory pipe coating. Using the same exact outer coating system can further guarantee the integrity of the pipe coating and ensure the protection of the entire pipeline.

Certified and qualified on-site team

Our team is extremely seasoned and qualified in this application. We have successfully completed many projects onsite at job locations and offer all types of field joint coating-related services from sand blasting, to application of underlying corrosion protection products, and the application of our pau wrap® coating as the ultimate top layer. Not only do we have experience in the application of our proprietary coating, our team also has mastered the application of the underlying coatings.


TDC’s pau wrap® pipeline mechanical protection products provide high quality, reliable protection of pipelines through the entire logistics handling to the pipeline construction phase. Using our customisable pau wrap® product range for both the pipes, as well as the field joints enables our customers to minimize the necessities of repairing, rehabilitating, or worst case, replacing a pipeline in the near future.
