3 Layer PE Coating Steel Pipe Technical Instructions
Structure of the 3PE coating steel pipe
Three layer PE coating anti-corrosive steel pipe carry out the standard of GB/T23257-2009 and DIN30670.
Structure:inner steel pipe,epoxy powder coating,middle layer of adhesive,outer layer of high density polyethylene
3LPE coating manufacturing process
Production process
Steel pipe inspection→Steel pipe pre-heating→Steel pipe shot-blasting→Anchor pattern depth/Cleanness inspection→Steel pipe medium→frequency heating→Epoxy powder spraying→Adhesive coating→Polyethylene Wrapping-Water cooling to 60ºC below→Online electric spark→Pipe end treatment→Finished product inspection→Product marking→Certification sticking→In storage
