precision seamless steel pipe
Strong Strength, High-Quality Products

Precision seamless steel pipe description

Precision seamless tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of precision steel tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used to produce pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless tube. There are also chemical components of welded pipe precision steel pipe, carbon C, silicon Si, manganese Mn, sulfur S, P, chromium Cr, seamless steel pipe and round steel and other solid steel, in bending and torsional strength at the same time, light weight, is a kind of economic section of steel, widely used in the manufacture of structural parts and mechanical parts.

Precision seamless steel pipe advantage

1. High precision, saving the loss of mechanical processing users.
2. Many specifications, wide range of applications.
3. Cold rolled products have high precision, good surface quality and good straightness.
4. The inner diameter of the steel pipe can be made into hexagonal shape.
5. The steel pipe has better performance and the metal is relatively dense.

Precision seamless steel pipe application

The inner and outer walls of the steel pipe have no oxide layer, withstand high pressure, no leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, surface anti-rust treatment, It is widely used in hydraulic system steel pipe, injection molding machine steel pipe, hydraulic press steel pipe, Marine manufacturing steel pipe, EVA foaming oil pressure machinery, precision oil pressure cutting machine steel pipe, shoe making machinery, hydraulic equipment, high pressure oil pipe, hydraulic oil pipe, clamp joint, steel pipe joint, rubber machinery, forging machinery, die casting machinery, engineering machinery, concrete pump car with high pressure steel pipe, sanitation car Automobile industry, shipbuilding industry, metal processing, military industry, diesel engine, internal combustion engine, air compressor, construction machinery, agriculture and forestry machinery, can completely replace the same standard of imported seamless steel pipe.
