Product Description

High standard precision seamless tube 4130 steel price

1. Hydraulic Cylinder Tube------Main products of Xinpeng,

Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.

2.SRB tube ----- used in Elevator buffer and Hydraulic Cylinder .

This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M.

3. Cold finished tube---- Widely Used.

Processing range 30-300mm, biggest length is 11M.

Xinpeng Have passed ISo9001 verified from 2015; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.

Best quality cold rolled tube manufacturer, cold rolled pipe

Hydraulic cylinder tube is a kind of after cold rolling processing of a kind of high precision steel tube, full name cold rolled precision seamless steel tube. Precision seamless steel tube wall inside and outside the precision seamless steel pipe seamless steel pipe without oxidation layers, under high pressure without lea, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc. It is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, are made seamless tube. The chemical composition of precision seamless steel tube with carbon sulfur C, Si, Mn, S, P, Cr.

The difference between precision steel pipe and seamless pipe:

1. The seamless steel tube with obvious difference is that dimensional accuracy can be up to 0.1mm.

2. High precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

Hydraulic cylinder tube features:

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
