SAE1020 /St37.4/ St52 High-Precision Cold-Rolled Steel Pipe
Precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Precise steel pipes are mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, due to their advantages such as no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation during cold bending, flaring, flattening and no cracks The precision steel pipe has high dimension accuracy, high internal and external surface finish, no oxide film on the internal and external surfaces of the steel pipe after heat treatment, no crack on the expanded and flattened steel pipe, no deformation during cold bending, and can withstand high pressure, and can be used for various complex deformation and deep mechanical processing.
Haihui steel pipe is specialized in custom production of high quality seamless steel tubes under international standards ASTM A519, ASTM A106, ASTM A500, ASME SA500, DIN2391, DIN1629, EN10305-1, DIN17121, EN10297-1, JIS3441, JIS3444 and JIS3445. We provide small batch customization service, especially for small and medium-size enterprises. Raw material, internal and external dimensional tolerances and consistency, internal and external surface roughness, straightness, mechanical properties, eccentricity, special shape, alloy steel, small-diameter thick-walled seamless steel tubes all can be customized. The production range for outer diameter is from 10 to 120mm and for wall thickness is from 1 to 20mm.
