Coating equipment

Field joint coating excellence

Allseas is at the forefront of FJC technology, combining decades of hands-on experience with continuous investment in research and development to deliver coating solutions for pipeline welds that our clients can trust. 

Our in-house coating equipment, including grit blasters, induction heaters, powder spray systems and sheet wrap systems, ensure unmatched durability and protection to shield the joint against corrosive and mechanical forces. Every joint we coat reflects our commitment to quality and reliability, meeting the most stringent industry and requirements.

Sheet wrapper coating system

Launched in 2023, our sheet wrapper is a breakthrough in field joint protection, offering the strength and durability of linepipe-quality coatings. This advanced, automated system applies a polyolefin top layer over an anti-corrosive coating, sealing each joint with precision. By minimising human interaction and optimising overlap adhesion, this system improves quality and speeds up cycle times.

The automated process enhances safety, while in-house polyolefin sheet production reduces delivery times and supply chain delays. Following years of development and rigorous testing, this innovative solution is setting a new industry standard in field joint coating quality and accuracy, delivering 100% coating results every time.

Injection moulded polypropylene

This cost-effective automatic process helps reduce cycle times and enhances the final quality. Applied at thicknesses between 10 to 100 mm, this advanced coating is achieved by melting polypropylene at high temperatures and injecting it under pressure into the field joint cavity, creating a seamless bond with the factory-applied coating. 

Our specialised injection moulded polypropylene (IMPP) equipment works alongside a range of auxiliary machines, including a bulk handling system for precise material mixing and an infrared preheating machine to prepare the joint. This innovative setup ensures optimal adhesion, maximises durability, and sets a new standard for field joint coating quality and performance.

Fusion bonded epoxy 

Fusion bonded epoxy (FBE) coating machines offer advanced anti-corrosion protection for pipelines, accommodating pipes up to 48 inches with any cut-back lengths. Fully automated and adaptable to various concrete weight or thermal insulation coating thicknesses, these machines enable the application of both single and dual-layer coatings, including FBE and chemically modified polypropylene/Ethylene (CMPP/E), in a multiple passes.

The FBE process begins with precise pre-heating of the joint area using close looped induction heating, followed by the efficient application of powder coatings. Optimised with years of field expertise, our FBE coating system provides robust standalone protection or a primer layer in multi-layer coating systems, ensuring long-lasting durability and optimised performance to meet any project requirement.

Infrared (HSS) blaster

Our automated infrared sleeve application system delivers superior coating protection for field joints. The high-power, contactless infrared equipment replaces manual application with a precise, contactless system that ensures uniform heat distribution, optimising adhesion and coating quality.

The infrared blaster accommodates various coating types and pipe diameters, featuring interchangeable heating coils for both heat shrink sleeve (HSS) and injection-moulded polypropylene (IMPP) coatings. By automating the sleeve application process, our infrared system boosts productivity, enhances safety, and delivers consistent, high-quality results on every joint

Surface cleaning

Our automated power wire brushing and grit blasting machines provide efficient, high-standard surface cleaning to prepare field joints for coating in line with global standards. These machines use multiple cleaning heads with recirculation units and can handle varied coating thicknesses. Configurable and automated, they adapt easily to different project requirements, ensuring a clean, consistent surface every time.

Induction heating

Powered by in-house software and an automated closed-loop control system, our induction heating systems ensure fast, uniform heating enhancing efficiency and safeguarding quality at every stage. With a modular design, these machines adapt to any pipe diameter, cut-back length and coating thickness, delivering an accurate heat profile with optimised cycle times.
