45# seamless steel pipe is made of high-quality carbon steel, fine drawn, non-oxidizing bright heat treatment (NBK state), non-destructive testing. The inner wall of 45# seamless steel pipe is brushed with special equipment and subjected to high-pressure washing, rust-proof oil on the 45# seamless steel pipe is used for rust-proof treatment, and both ends are sealed for dustproof treatment.

45# seamless steel pipe has high precision and good smoothness. After heat treatment, the inner and outer walls of 45# seamless steel pipe have no oxide layer, and the inner wall is clean. The 45# seamless steel pipe bears high pressure, does not deform under cold bending, flares and flattens without cracks, and can make various complex deformations and machinery processing.

Application of 45# seamless steel pipe:
45# seamless steel pipe is widely used as steel pipe for hydraulic system, steel pipe for injection molding machine, steel pipe for hydraulic press, marine steel pipe, EVA foaming hydraulic machinery, steel pipe for precision hydraulic cutting machine, Shoe machinery, hydraulic equipment, high-pressure tubing, hydraulic tubing, ferrule joints, steel pipe joints, rubber machinery, forging machinery, die-casting machinery, engineering machinery, high-pressure steel pipes for concrete pump trucks, sanitation vehicles, automotive industry, shipbuilding industry, metal Processing, military industry, diesel engines, internal combustion engines, air compressors, construction machinery, agricultural and forestry machinery, etc.
