Pipes and pipe components can be given an external coating to extend their service life. The coating is usually polyethylene (PE), applied by hose extrusion (over an epoxy primer base) to pipes that are to be buried in the ground.
Specifications: - PE coated to DIN 30670N/n or EN 6901/6902, standard layer thickness with epoxy base layer (3-layer coating) using the hose extrusion process
- Color: standard is yellow; black is available
- Layer thickness: up to 4" external diameter: minimum 1.8 mm. Larger external diameter: minimum 2 mm
- If required, the KIWA mark can be applied (for delivery to the Netherlands)
Other options: - PE coating using the sintering method
- External PE coating combined with internal cement lining
