Coated enough pipe is in big caliber spiral pipe and high frequency pipe based Shang coated enough plastic and into, maximum tube mouth diameter up 1200mm, can according to different of need coated enough PVC (PVC), and polyethylene (PE), and epoxy resin (EPOZY), various different performance of plastic coating, adhesion good, anti-corrosion sex strong, can resistance acid, and alkali and the other chemical corrosion, nontoxic, and not rust, and wear, and resistance impact, and resistance penetration sex strong, pipeline surface smooth, not stick attached any material, can reduced conveying Shi of resistance, Traffic and transportation efficiency, reduction of pressure loss. Solvent-free coatings, no exudate material, which does not pollute the transmission medium, so as to ensure the purity of the fluid and the health of at-40 ° c to + 80 ° c range of alternating hot and cold cycles, no aging, no cracks, which can be used in demanding environments such as cold.

Large diameter coated steel is widely used in water supply, natural gas, oil, chemical, pharmaceutical, communications, electric power, marine engineering.
