Datong Hydraulic

honed hydraulic tube  is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g.   Hydraulic Tubes .  During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface. ADVANTAGES OF OUR HONING TUBE 1, High precision tolerances; Our honed steel tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2, Seamless tube with high pressure resistance; We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can ...

The required barrel is a key part of hydraulic cylinder , and sometimes the direct acting component of hydraulic cylinder (when piston rod or plunger is fixed); the barrel, end cover and piston (plunger) form a sealed chamber for containing pressure oil and driving the load for acting; thus the barrel has requirements for strength, rigidity and sealing as below: (1) The barrel should have sufficient strength to prevent permanent deformation under long-term rated operating pressure and short-term dynamic test pressure. (2) The barrel should have sufficient rigidity to prevent bending caused by lateral force imposed by the piston and reacting force during installation. (3) Reliable seal: The grade of dimensional tolerance and accuracy of geometric tolerance of cylinder inner surface, piston seal and supporting ring should be designed rationally to ensure reliable seal and reduce wear. (4) The cylinder barrel to be welded should have good weldability to avoid cracking or excess...
