EXTERNAL COATING
EUPEC is approved by all of the majors in the Oil and Gas industry and has a reputation for finding external coating solutions to even the most complex technical and quality requirements.
There are two types of product on the market; epoxy coatings and three layer polyolefin coatings.
Epoxy Coatings
Fusion-bonded epoxy (FBE) coatings are well known for their anti-corrosion properties over a wide temperature range. Their high resistance to cathodic disbondment, long-term adhesion to steel and ability to be stored in all climatic conditions make these thermosetting coatings an environmentally safe industry standard.
Dual-layer, fusion-bonded epoxy (DFBE) coatings combine the strengths of the mono layer with a second layer acting as mechanical protection.
Three-layer Polyolefin Coatings
These coating systems combine the performance of epoxy with the mechanical protection of polyolefin, which may be polyethylene (3LPE) or polypropylene (3LPP).
A copolymer adhesive layer binds the two products. Both coating systems have excellent adhesion properties and offer proven high resistance to impact and cathodic disbondment. They provide optimum stability over many years and their combination with adequate cathodic protection is guaranteed to prolong the life of the pipeline.
3LPP coating has the advantage of providing high temperature mechanical performance during production. This mechanical strength also proves valuable during transport, handling and the laying phase.
CONCRETE WEIGHT COATING
Concrete weight coating provides negative buoyancy for subsea lines, mechanical protection during handling, transportation and laying operations, and protects the line during its lifetime in a marine environment.
Concrete is prepared with different specific gravities and thicknesses using high quality iron ore and other key raw materials. It can be applied over anti-corrosion or insulation coatings while the reinforcing wire-mesh is wrapped and incorporated in the concrete.
EUPEC provides compression-wrapped reinforced concrete depending on the pipe diameter and the scale of the project.
​
The EUPEC process also includes anode installation to provide an efficient cathodic protection system. If required for specific projects, our mobile plants can be deployed in close proximity to the lay site, providing local employment and logistical and cost benefits.
THERMAL INSULATION
EUPEC provide tailor made thermal insulation coating systems for subsea pipelines to optimize flow assurance, and provide insulation for pipelines through our multi-layer polypropylene (5LPP/ MLPP).
​
The main insulation thickness can be solid or foamed depending on the project requirements (water depth, laying conditions, working conditions, fluid temperature and insulation properties).
