3PE 3lpe Steel Pipe Anticorrosion Layer Application Coating Line
Description
The coating manufacturing process consists of the following operations:
The surface blast cleaning to Sa 2 1/2 acc.To ISO 8501-1,
The electrostatic spraying of epoxy powder onto a heated pipe,
Wrapping a pipe with extruded copolymer,
Wrapping a pipe with polyethylene/polyetylene in continuous way,
Cooling the coating and dressing the pipe ends.
An extruded polyethylene coating has higher mechanical properties in comparison with cold applied polyethylene tape coating.Anti-corrosive coatings made of three-layer PE/PP are characterized by:
High mechanical strength,high adherence of the coating to the pipe,guaranteed long lastinganticorrosiveprotectionofundergroundpipelines for minimum 50 years,100% protection of weld zone of coated longitudinally and spirally welded pipes,suitability for bending of coated steel without damaging the insulation layer.
