The external coating in polyethylene is applied on steel pipes for buried or submerged pipelines for water and methane as well as on gas distribution pipes. Coating thickness depends on pipe diameter and which UNI 9099 typology (see table) is requested. The three layers polyethylene coating offers a long lasting corrosion protection, high resistance and strong adhesion with service temperature from -20° C to a maximum +60/80° Celsius. The black pipe is sandblasted by metallic grit to SA 2.5 according to ISO 8501-1 standard, then a first layer of primer is applied, the second layer consists in polyethylenic adhesive and the third in polyetyhlene layer. After cooling the coating is cut back on pipe-ends and checked as per UNI 9099/DIN 30670: visual inspection, control on thickness, dielectric continuity and technological tests.

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.
