Large diameter coated steel pipe is made of large diameter spiral welded pipe and high frequency welded pipe on the basis of plastic, the largest nozzle diameter of 1200mm, according to different needs coated with polyvinyl chloride (PVC), polyethylene (PE) Epoxy resin (EPOZY) and other different properties of the plastic coating, good adhesion, corrosion resistance, can be resistant to strong acid, alkali and other chemical corrosion, non-toxic, non-corrosion, wear, impact resistance, Strong, smooth surface of the pipe, do not adhere to any material, can reduce the resistance when conveying, improve the flow and delivery efficiency, reduce the transmission pressure loss.

The coating without solvent, no exudate substances, which will not pollute the transmission of the media, so as to ensure the purity of the fluid and health, -40 ℃ to +80 ℃ range of hot and cold cycle can be used intermittently, Not cracked, and thus can be used in harsh environments such as cold areas.

Large diameter coated steel pipe is widely used in tap water, natural gas, petroleum, chemical, pharmaceutical, communications, electricity, marine and other engineering fields.
