Skived and roller burnishing Hydraulic cylinder Tubes

 

What we want to say:

Dear Sir/Madam, Welcome~

We are Yantai Xinpeng Steel Pipe Co.,Ltd

♦ Professional tube manufacturer which have over 20years experience 

♦High reputation in tube 

Product Introduction: 

 

hydraulic cylinder tube st52 din2391 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.

 

Features:

 

hydraulic cylinder tube st52 din2391  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

 

Why you choose us as your best choice?

 

• Our quality is the top five in China. Raw material is mainly from some famous refinery steel mills, such as BAO STEEL, Tianjin, and Chengdu etc, which are the best and largest raw material manufacturers in China.
• We have been through ISO9001:2008 international quality system certification.
• Warranty period for our honed tubes and chrome bars is 2 years. For some special or important customers, the period is 5 years.
• All the orders, records of production and inspection would be kept for 5 years
• High Precision:

 

Honed tube (Roughness of tube is 0.2μm and straightness is less than 0.15/1000), Product details are completely according to International Standard, (Most of domestic mills don’t do this in order to reduce cost)

 

• Delivery time is very fast. The average delivery time is 5-30 days after confirming the orders.
• Package: banding with steel strips, braiding parcel at outside
• Conservation: Anti rust oiled coating on the inside and outside of the surface, plastic caps at both ends.
