Main use of honed pipes

- Aug 14, 2019-

Main uses of honed pipes: hydraulic and pneumatic cylinders; hydraulic lines; tubes for spinning, textile and printing machines; tubes for automobile shock absorbers; shaft sleeves; piston rods and precision alloy steel tubes. According to the customer's request, it can also provide: fixed length pipe, honing pipe and special heat treatment pipe. The honing pipe is the main body of the hydraulic cylinder, and the inner hole is generally manufactured by precision machining processes such as boring, reaming, rolling or honing, so that the piston, its sealing member and the supporting member can smoothly slide, thereby ensuring the sealing effect and adding wear; The honing pipe is subjected to a large hydraulic pressure and, therefore, should have sufficient strength and rigidity.

 

Unlike honing, the honing process uses a honing head to extend into the hole, and then the machine rotates, reciprocates, and rises out of the grinding bar to stop the cutting process. The machine is a common honing machine. There are vertical and horizontal The vertical type is more suitable for the consumption of shorter parts in large quantities, such as cylinder liners. Horizontal type is more suitable for long-term consumption. Assuming that it is processed cast iron, the consumption efficiency is several times higher than that of internal grinding. However, the honing efficiency of steel parts is worse than that of cast iron, but it is much faster than the internal grinding method. The precision is not the effect, it is more than the inner grinding.

 

A honing pipe is a high-precision steel pipe material that has been cold-drawn or hot-rolled. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure and no leakage, high precision, high brightness, no deformation, cold cracking, flattening, and flattening without cracks, they are mainly used for the consumption of pneumatic or hydraulic components such as cylinders or The cylinder can be a seamless tube. The chemical components of the honing pipe are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
