With the development of pipeline steel plate technology and the progress of welded pipe forming and welding technology, the application scope of welded pipe for pipeline is gradually expanding, especially the advantage of welded pipe in the range of large-diameter group distance is more obvious and wet, coupled with the cost factor, welded pipe has occupied the leading position in the field of pipeline pipe, limiting the development of stainless steel seamless pipeline pipe.

 

In 2004, the output of seamless pipeline is about 400000 tons, and the steel grade includes x42-70. The varieties include onshore pipeline and submarine pipeline.

1.Seamless alloy and carbon steel tube Widely used in oil,drilling, gas, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and AISI 1020. We can also offer as customized seamless steel tube.

2.precision steel tubes

cold drawn steel tube/cold rolled steel pipe The cold process can remove the oxide layer outside to improve surface and offer better mechanical property, also can change ID,OD,WT to meet every client request.

3. Honed steel tube&SRB steel pipe

ID Tolerance: H8H9 or as client's request

ID Roughness: RA0.4micron(max)

Length: 6m(max)

Inner roughness: Ra0.2-0.8um

Straightness: 1:1000 or customized

This process can improve the roughness of the inner tube to 0.2-0.8um and make tube for cylinder using directly.

4.Hydraulic cylinder steel tube  

Hydraulic cylinder tube inside and outside the wall without oxidation layer, under high pressure, no leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, surface rust proofing

1. The smaller outer diameter

2. High precision to do small batch production

3. Cold drawn finished products of high precision, good surface quality

4. The steel pipe transverse area is more complex

5. Steel pipe is superior performance, dense metal
