Hydraulic honed tube
Description
Longyue's hydraulic honed tube is produced using our "Suitable To Hone" Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS).
The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes.
Honed tube is ready to use for hydraulic cylinder applications without further ID processing.
