Pipe Coating Products
Fusion Bonded Epoxy – Fusion Bond Epoxy is a powder epoxy thermosetting coating applied for
anticorrosion protection to steel pipelines. The pipe is first blast cleaned and heated. Then
epoxy powder is spray applied by electrostatic guns to melt and form a uniform layer that
hardens within a minute from application. Utilizing industry accepted materials supplied by
manufacturers such as 3M, DuPont, and Valspar, the facility can apply FBE in a wide range of
thickness to cost effectively meet any project specifications.
Fusion Bonded Epoxy with Abrasion Resistance Overcoating (FBE/ARO) – Utilizing two
completely separate powder systems, the facility can produce FBE with an ARO at unprecedented
processing speeds using industry accepted materials such as 3M 6352, DuPont 7-2610, and Lilly
2040.
Fusion Bonded Epoxy with High Temperature Resistant Overcoating – Utilizing two completely
separate powder systems, the facility can produce FBE with a high operating temperature
resistant overcoating such as DuPont’s Nap-Gard Gold and 3M’s 6258.
Fusion Bonded Epoxy with Zap-Wrap Overcoating – The facility is capable of processing line
pipe with connections and of applying the Zap-Wrap abrasion resistance overcoating to the
ends of each pipe.
Three Layer Polyethylene (3LPE)
To improve anticorrosion performance and adhesion, an additional layer of epoxy primer is
sprayed onto pipe surfaces prior to the adhesive layer and Polyethylene top layer
application. Three Layer Polyethylene is suitable for service temperatures from 60°C to 80°
C (85°C peaks). Typical coating thickness is from 1-2 mm to 3-5 mm.
Three Layer Polypropylene (3LPP)
If a wider service temperature range and high stiffness is required, adhesive and top layers,
applied over primer layer, are based on polypropylene instead of polyethylene. Three Layer
Polypropylene is suitable for service temperatures up to 135 °C (140°C peaks). Typical
coating thickness is from 1-2 mm to 3-5 mm.
Three Layer Polypropylene and Polyethylene
Three Layer applications involve a thermoplastic coating applied to steel pipelines as a form
of anticorrosion protection. This mechanical resistance is appropriate when the risk of
particularly severe coating damages exist. The Three Layer process involved several steps.
First, the pipe surface is blast cleaned to remove any external residue from the mill or
storage. It is then heated and sprayed with a Fusion Bond Epoxy (FBE) primer followed by the
application of an adhesive copolymer and polyolefin polymers that are wrap extruded, one over
the other.
