After acid pickling, cold rolling, cold drawn, and then adopt advanced technology for high temperature heat treatment (NBK status) to produce steel pipes with surface: bright, smooth, high precision, high polish, both inside and outside wall without oxidation layer, internal and external wall of high precision, mechanical performance fits well in any Angle bending, and can bear high pressure, cold bending deformation, flaring, flattening, tensile and other require ments, our steel tube doesnot burst when cold bending, no cracks, no oxide layer and the internal and external wall, etc.

The precision steel tube is made by seamless steel tube, which is through non-oxygen tempering treatment to eliminate the surface and internal stress.

The product is of high precision and ductility, easy to be processed into various required shapes, and cross section of the tube will not be reduced or flattened.

The surfaceis of high presicion, and the surface hardness is moderate and easy to be connected.

The inner hole and surface are treated with phosphating anti-rust treatment without acid cleaning and rust removal.

The company covers an area of more than 8000 square meters with an annual output of more than 5, 000 tons.

The main products are: cold drawing or cold rolling precision seamless steel pipe and related supporting bright tubing, conveying fluid seamless steel pipe.

Our company produce seamless steel pipe in Europe (Germany) DIN series standard is the basic standard, using high quality tube blank, on the basis of this combined with our unique steel pipe manufacturing process, .

Steel pipe is produced in high precision and high cold drawn.

Because of the special bright heat treatment process, the inner and outer walls of steel tube are not oxidized after heat treatment.

ANSI SAE 4130/JIS SCM430 25crmo4 1.7243 structural alloy seamless steel tube, 4130 drilling pip, sae 4130 steel tube, 4130 bike frame

we can also produce tube or rolloer according to drawings
