Pre-Heat Treatment: Induction or infrared
RAE offers two types of Pre-Heat Treatment methods: Induction Coil Heating for anti-corrosion coatings or Infrared Heating of the parent coating for thermoplastics or thermoset coatings. Each system supplies uniform, reliable heating to the steel pipe or parent coating for improved bonding with the next protective coating application.
-
The Tesi Clamp Coil heating system is composed of inductors (coils) and an induction generator to guarantee uniform heating of the steel pipe. The induction heat coils are qualified during the PQT process before onsite delivery.
The Infrared Heater is designed to be used in combination with RAE’s IMPP/SPU coating equipment. The closed-loop infrared heater supplies reliable heating of chamfer and overlap areas to result in a homogenous bond between the parent coating and IMPP or SPU coating.

Rapid Thermoplastic Coatings:
Rapid 3LPP or 3LPE Wehocoat
RAE’s Rapid Wehocoat system is an advanced 3-layer FJC system that offers a directly extruded film of material, applied to a hot FBE and adhesive coated cutback region and fused to the parent coating. It utilizes automation, faster application time (e.g., 2-3 min cycle time for a 10-in pipe), and quick changeover time from IMPP to Wehocoat.
-
Our Rapid Wehocoating platform utilizes laser-guided pipe alignment technology.
Direct extrusion of a melt film onto the pre-applied FBE and adhesive provides a coating with minimum thermal and mechanical history for high performance.
The high level of automation minimizes the risk of operator error.
With full fusion to the parent coating and high level of ductility ensures reel-ability.
Provides a thin coating and thin overlap (1-2 mm) to minimize issues with tensioner load transfer and reduces overlap stress levels.
The modular construction of the equipment enables quick changeover time from IMPP to Wehocoat.
Our standardized libraries of pipe and coating geometry allows for fast changeover times for different pipe sizes, as well as reliable repetition of application conditions from PQT to production.
Fast application time - 1-2 m/min (dependent on extruder output and thickness).
Wehocoat is mobilized, complete with an extrusion plant, on tailor-made skids integrated into the process.
Both systems are compatible with the RAE EDGE remote data management application.

Thermoset Coatings:
IMPU, Calour
RAE’s Thermoset Coatings system applies IMPU to welded joints utilizing an automated PLC-controlled infrared heater and PLC-controlled SPU pump system. The system is also used to apply Calor coatings - a three-component resin - which offers increased durability, higher operating temperatures, and faster cycle times than SPU coatings.
-
Our IMPU machine utilizes laser-guided pipe alignment technology. IMPU coatings can be applied at a spoolbase or on a lay barge.
Our Calour coating is a mercury-free, epoxy-polyurethane alloy system with superior thermal and hydrolytic stability compared to standard PU systems. It is ideal for a wide range of moulding applications where toughness and fast cycle times are required.
Both systems are compatible with the RAE EDGE remote data management application.
-
IMPU: Suitable for shallow or deepwater pipelines, often used in insulated and concrete coated pipelines, as well as pipelines placed in river crossings.
Calour: Applications include oil and gas flow lines, field joints, bend stiffeners, bend restrictors, VIV strakes, cable protection products, and custom coating line pipe applications.

Manual Application:
LE, MCL, FSPP, FSPE
RAE’s Manual Coating services are used for coatings such as LE, MCL, FSPP, and FSPE. Whether applied by brush, sponge, a paint spray kit, flame sprayer or handheld extruder, RAE has extensive experience with these manual coating processes at a spoolbase or aboard a pipelay vessel.
-
RAE’s Manual Coatings utilizing handheld application tools can be applied to pipes of any diameter.
LE coatings can be applied by brush, spray, or roller to provide anti-corrosion protection. It is most commonly used for pipeline field-joints, tie-ins, fittings, fabrications, FBE repairs, and the maintenance of existing pipelines.
MCL coatings are applied using an automated spray system for higher productivity and consistent application.
Flame Spray coating - whether polypropylene or polyethylene - is a cost-effective method that can be applied across a wide variety of components and structures to prevent corrosion.
Both systems are compatible with the RAE EDGE remote data management application.
-
LE: Provides mechanical protection for subsea production lines, underground storage, or pipelines. Works as a primer before HSS application; or externally as a second layer over FBE for abrasion protection.
MCL: Provides corrosion protection for field joints, valves, and bends. Offers fast application for high productivity.
FSPP: Offers great mechanical protection, high heat resistance, and anti-corrosion properties. Ideal for tie-ins, pipelines operating at moderate temperatures, and custom pieces like bends, flanges, and difficult-shaped pieces.

-
An essential step in the coating process, Quenching is used to cool down the coated field joint before reeling or directly installing it along the ocean floor.
Quenching provides additional abrasive mechanical protection during the reeling and installation process by cooling the applied coating and thus hardening the materials before the pipe travels over the rollers.
-
Requires 1-2 operators to monitor and operate the equipment. Training and certifications are provided by RAE upon request.
Weight Stabilization:
HDPF
RAE’s HDPF Coating services provide mechanical protection and weight stabilization for Concrete Weight Coated (CWC) subsea pipelines installed in shallow waters. HDPF coatings can be applied in a wide range of weights, thicknesses, and diameters. It is common to apply the HDPF coating over anti-corrosion and/or mechanical protection coating materials such as HSS.
-
RAE’s HDPF machines are compatible with the RAE EDGE remote data management application.
-
HDPF provides thermal insulation, mechanical protection, weight stabilization, and high heat resistance for subsea pipelines installed in shallow waters.
HDPF consists of FBE, PUF, and PE coating materials to help build up the thickness of the FJC to that of the CWC infill. In addition to its protective properties, HDPF provides a negative buoyancy, which prevents the pipe from floating in high water table terrain, such as swamp land.
-
Requires 1-2 operators to monitor and operate the equipment. Training and certifications are provided by RAE upon request.
Heat Shrink Sleeves:
HSS, PP, PE, or Hybrid
RAE’s Heat Shrink Sleeve (HSS) Coating service offers an easy, cost-effective solution to provide protection from corrosion, mechanical damage, and works well in high heat environments. The shrinkable materials (PP, PE, or Hybrid in combination with LE primer) provides a strong bond, and provides protection during pipeline installation activities.
-
HSS has excellent anti-corrosion and mechanical protective properties.
For high-heat applications, the PP HSS can withstand temperatures up to 130 degrees C.
The shrinkable material (polyethylene) fills any imperfections in the steel. A strong bond (aggressive mastic sealant) prevents air or water from reaching the bare steel.
HSS protects during backfill, stays in place through contraction and expansion of the pipeline, and prevents external forces from exposing the previously bare metal of the field joint to air or water.
The backing is generally a sheet of high or low-density crosslinked (via radiation) PE or PP that is pre-stretched. Adding thickness to this layer enhances mechanical protection.
-
Requires 1-2 operators to apply the HSS materials to the piping. Training and certifications are provided by RAE upon request.
