Seamless Hydraulic Srb Pipe

Product Detail

Seamless Hydraulic Srb Pipes Introduction

Seamless Hydraulic Srb Pipes are presicion tubes with smooth inside , they also could be skived and burnished pipe. Tubes or pipes inside tolerance could be H10, H9 or H8. Outside tolerance, wall thickness tolerance are produced according to seamless cold drawn tubes for precision application standard GB/T3639-2009 , EN10305 or DIN2391 standard. Material SAE1020, 20#, ST45, CK45, ST52, E355 tubes and so on for you to choose. IF you are looking for seamless cold drawn honed tubes or SRB tubes for hydraulic cylinder pipes or pneumatic cylinder tubes, please contact us without any hesitation.

Quality control

1. We only buy raw material from famous tube factory, and Checking raw material quality before production.

2. We check the tube ID tolerance, OD tolerance and surface after cold drawn one by one.

3. We inspect the honed tube inside tolerance and surface again one by one after honing or skiving.

Our Advantage

1. We has two factories of 40000 square meters and totally 150 employees to promise the Honed Tubes In Stock best quality control;

2. According to the cylinder pressure and inside diameter size ,different hydraulic cylinder honed tube Would be choosed ;

3. Our motivation is --- customers’ satisfaction smile;

4. Our believing is --- pay attention to every detail;

5. Our wish is ----perfect co-operation.
