Polyurethane anti-corrosion steel pipe
Manufactured by spray or pour application of two-component liquid polyurethane (PU) onto blast-cleaned steel pipe surface, forming a seamless, elastomeric protective layer. Features excellent abrasion resistance, high mechanical strength, good cathodic disbondment resistance, and outstanding resistance to impact, cavitation, and seawater.
Manufactured by filament winding continuous glass fiber rovings impregnated with thermosetting resin (polyester, vinyl ester, or epoxy) onto the external surface of steel pipe, followed by curing. Features excellent corrosion resistance, high mechanical strength, good electrical insulation, and lightweight compared to solid steel.
Produced by welding or seamless forming followed by hot-dip galvanizing, which applies a uniform zinc coating for excellent corrosion resistance. Features smooth internal and external surfaces, good ductility, and strong coating adhesion.

Produced by cold drawing or cold rolling from stainless steel coil or billet, followed by annealing and pickling to ensure excellent corrosion resistance and uniform mechanical properties. Available shapes: round, square, rectangular.
