To increase the reliability and duration of exploitation of pipelines, their anti-corrosion protection is necessary. One of the modern and most effective methods of protection is highly reinforced insulation, which is carried out with extruded polyethylene in the factory workshops. Coating on insulation pipes is applied in 2 or 3 layers, with a total thickness of 2 – 3.5 mm. For strong adhesion of the pipe surface with the applied coating, a special primer is preliminarily applied for. The protective anti-corrosion layer of the insulated VUS pipe includes:
- adhesive material;
- epoxy primer;
- polyethylene coating.
