Chrome Plated Cylinder Barrel Introduction
Chrome plated Honed Tubes are presicion tubes with smooth inside and with chrome plated , 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 chrome plated tubes for hydraulic cylinder pipes or pneumatic cylinder tubes, please contact us without any hesitation.

Production process
Raw material – annealing for material of 45#, 27SiMn, 25Mn – Acid cleaning – parkerizing & Saponifying – cold drawn – leveling – saw off bad section – stress relieving – leveling –honing or skiving – chrome plating - inspection – oiled plated - packing
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.
4. We measure the chrome thickness .
