Yantai Xinpeng Steel Pipe Co,.Ltd. is one of the best suppliers of the precision tube and hydraulic cylinder tube in North of China. Since 2002 cold drawn machine set importing, Xinpeng become a big precision steel pipe manufacturer with 500Mt month productivity in the next 12 years.

Products widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator, forklifts and the Petrol industry.

Hydraulic cylinder tube is a kind of after cold rolled processing of a kind of high precision steel tube. Precision seamless steel tube wall inside and outside are 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.

The difference between precision steel pipe and Mild 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.

3. The smaller outer diameter.

4. High precision to do small batch production surface quality

5. ISO9001:2015 verified supplier, quality is better.
