Low Temperature Steel Pipe

Produced by seamless or welded process from low temperature carbon steel or alloy steel, designed to maintain high toughness and impact resistance at sub-zero temperatures down to -196°C. Features fine grain structure, excellent low-temperature impact properties, good weldability, and compliance with stringent NDE requirements.

Stainless steel round tube

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.

Aluminized pipe

Produced by hot-dip aluminizing of carbon or alloy steel tube, forming a continuous, intermetallic aluminum-iron alloy layer with an outer pure aluminum coating. Features excellent resistance to high-temperature oxidation, good corrosion resistance in sulfur-containing and high-temperature environments, and improved heat reflectivity.

FRP Filament Wound Pipe

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.

High-pressure boiler tubes

Manufactured by seamless cold drawing or hot rolling from killed carbon steel or alloy steel, designed for high temperature and high pressure service. Features excellent creep rupture strength, good oxidation resistance, fine grain structure, and dimensional accuracy.

FBE Coated Steel Pipe

Produced by electrostatically spraying thermosetting epoxy powder onto preheated steel pipe surface, where the powder melts, flows, and cures into a uniform, continuous film. Features excellent corrosion resistance, strong cathodic disbondment resistance, good chemical resistance, and a smooth surface.

Polyethylene Coated Steel Pipe

Manufactured by applying three-layer polyethylene coating (fusion bonded epoxy + copolymer adhesive + polyethylene) onto the external surface of steel pipe. Features excellent corrosion resistance, high mechanical strength, good cathodic disbondment resistance, and long service life in aggressive environments.

Stainless steel square tube

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.
