Hydraulic cylinder Seamless Tube, also known as honing pipe or cold drawn honing seamless cylinder pipe, is one of the main steel materials for manufacturing hydraulic cylinder, honing pipe is the seamless steel pipe by cold drawing, shoveling, honing processing.
The most important processing is honing processing, which is why it is called honing tube or honing tube.
And the products that have not been honed are named pre-honed pipe or pre-Seamless Tube.
During the honing process, the inner diameter surface of the pre-honed tube becomes smooth and shiny after several hours of grinding, and the final honed tube has high accuracy and low roughness, allowing direct machining of the hydraulic cylinder barrel without further inner diameter machining.
Cold drawing honing seamless cylinder tube production and processing:
Raw material - pickling - pressing - cold drawing - stress relief - leveling - sawing - waste parts - honing - oil resistant coating - filler.
Steel Graded: ST52, STKM13C, SUS316
Length: 6-8m.
Size: ID range from 25 to 250mm
Straightness:0.5 /1000mm
ID Tolerance: ISO H8
OD Tolerance: +/-0.3mm
