Craig has been working within the pipeline coatings field since 1998, participating in some of the largest onshore and offshore construction projects worldwide.
Coating Specialist Services offers comprehensive support for your pipeline coating projects, including third-party inspection, onsite representation for procedure qualification trials (PQT), pre-production testing (PPT), and technical assistance from the start or throughout the project.
CSS can provide you with specialist coating assistance for field joint coating and linepipe for onshore landlines, offshore pipelay, horizontal directional drilling (HDD), spoolbase, and linepipe coating plants.
We can assist your coating team with the correct application methods and ensure that procedures are being followed so you meet the project specification requirements.
CSS is experienced in the following specialized field joint coating systems:
2LPP, 3LPP, 3LPE, MLPP, IMPP, IMPU, MCLS, FBE, HBE, AE, HSS, tape wraps, FiberTec HDD coating system, automated vacuum abrasive blast systems, and heat induction coils.
These are some of the most common types of field joint coatings used in pipeline construction and maintenance The selection of the appropriate coating depends on factors such as pipeline material, operating conditions, environmental factors, and project requirements.
Heat-shrink sleeves are thermoplastic sleeves that are applied over the welded joint and then heated to shrink tightly around the pipe. These sleeves provide excellent corrosion protection and mechanical resistance.
Epoxy coatings are commonly used for field joint protection due to their excellent adhesion, chemical resistance, and durability. They can be applied in liquid form and cured to form a tough, protective barrier over the joint.
Polyethylene tape wraps consist of a corrosion-resistant polyethylene backing with an adhesive layer that bonds to the pipe surface. These wraps are applied in multiple layers to provide a robust barrier against corrosion and moisture ingress.They can provide a life cycle cost analysis, helping stakeholders understand the long-term financial benefits of investing in quality coating systems.
Polypropylene coatings offer similar benefits to polyethylene tape wraps but are made from polypropylene materials. They provide excellent resistance to abrasion, impact, and chemical exposure.
FBE coatings are applied to pipe surfaces using a fusion bonding process, creating a seamless, durable coating that provides exceptional corrosion protection. FBE coatings are typically applied in factory settings but can also be used for field joint protection.
Liquid-applied coatings offer high flexibility and adhesion, making them suitable for field joint protection in challenging environments with temperature fluctuations and soil movement.
Some field joint coatings combine polyethylene or polypropylene tape wraps with a mastic layer applied between the layers of tape. The mastic layer helps to fill voids and provide additional corrosion protection.
Cold-applied bitumen coatings consist of bitumen-based compounds that are applied to pipe joints and then allowed to cure at ambient temperatures. These coatings offer good corrosion resistance and are often used in less demanding environments.
Composite systems combine different coating materials, such as epoxy primers with polyethylene tape wraps or FBE coatings with heat-shrink sleeves, to provide enhanced protection against corrosion and mechanical damage.
In environments where pipelines are susceptible to abrasion from rocks, debris, or other factors, specialized abrasion-resistant overwraps can be applied over the field joint coating to provide additional protection.
