Company Information

ST52.3 H8 tolerance Honed Tube/Hydraulic Cylinder Honed Tube/Burnished Tube

 

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

 

 

USED

    Our company mainly produces various specifications of cold drawn,rolled precision steel tube,hydraulic cylinder tube and SRB(skived rolled burnished) Tube, which are widely used in such industries as hydro-cylinder, automobile, engineering machinery, textile machinery, printing machinery, oil drilling, etc. Our company is also the distributor of several domestic well-known steel tube plants in Shandong, and mainly distributes seamless steel tubes of all kinds of materials.

Product Description

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.

 

 

 

YANTAI XINPENG STEEL PIPE offers an extensive range of seamless precision steel tubes. The seamless precision steel tubes can be used for a wide range of precision mechanical spare for car and cylinder accord to standard DIN2391/ EN10305-1/ GB/T3639-2009.
