Hydraulic cylinder tube also named honed tube or cold-drawn honed seamless cylinder tube, it is one of main steel materials for making hydraulic cylinders, honed tubes are to made from seamless steel tube through cold-drawn, relieving and honing processes.

Most important processing is honing processing, that’s why named honed tube or honing tubing.

And the products before honing processing named pre-honed tube or ready to honed tube.


During honing processing, ID surface of pre-honed tube is go through grinding several hours become smooth and shiny, final honed tube with high precision and very low roughness and could making hydraulic cylinder barrel directly without further ID processing.

Cold-drawn honed seamless cylinder tube production processing:

Raw Materia - Acid cleaning - Parkerizing - Cold-drawn - stress relieving - leveling - Saw off reject parts - Honing - Anti oil coating - Packing.
