Polyethylene (Epoxy) coated composite steel pipe
The coated steel pipe is the product of pe-modified polyethylene hot dip plastic or ep-epoxy resin coating, and the coated composite steel pipe is coated with welded steel pipe as the substrate, with sandblasting treatment, preheating, internal and external coating, solidification, etc. After-treatment and other processes made of steel and plastic composite pipe.Coated steel pipe is a product of hot dip plastic with PE- (modified polyethylene) or EP (epoxy resin) with internal and external coating. The coated composite steel pipe is coated with welded steel pipe as substrate, with sandblast shot blasting, preheating, internal and external coating, solidification, etc. Steel-plastic composite pipe made by post-treatment technology. It has excellent comprehensive properties, strong corrosion resistance and mechanical property, good chemical stability and water resistance, with drag reduction, anticorrosion, pressure resistance, antibacterial and so on.Generally speaking, it is not restricted by conveying medium, and the coating layer has strong adhesion with iron and steel. The coating material: epoxy resin (EP) is suitable for the working environment below 80 ℃. The coating of steel pipe has extremely high adhesion, high hardness and good impact resistance. And has good chemical corrosion resistance, design life up to 50 years.
