Steel pipelines are used for transportation of natural gas, crude oil, petrochemicals, and water at high pressure over long distances. In order to protect the pipes from corrosion, external coating and cathodic protection are used.
There are 5 common types of steel pipeline protection which are chosen depending on different environmental elements , costs and standards:
1. Three layer high density polyethylene (HDPE) for operating temperatures from -45⁰C to +90⁰C
2. Three layer polypropylene (PP) for operating temperatures up to +110⁰C
3. Fusion Bonded Epoxy (FBE)
4. Coal tar, asphalt enamel
5. Polyurethane (PUR)
Polyethylene-based systems offer excellent mechanical protection and long-term aging performance. The three layer high density PE is the most commonly used protection worldwide
A Three layer System consists of an epoxy primer and an adhesive to bond the epoxy primer with a polyolefin topcoat. Polyolefin-based systems offer excellent mechanical protection and long-term ageing performance.
Padena Polymer produces the top two layers (adhesive and HDPE) of the 3 layer steel pipe coating system.
