Honing Seamless Steel Pipe

Honing seamless steel pipes (hydraulic cylinder tube, pneumatic cylinder tube) produced by undergo cold forcing and annealing for a cured tensile strength reaching over 52kg/cm², before the pipes are milled by precision machinery, regulating the tolerance in inner diameter at an H8-H9 level, with surface roughness at between Ra 0.2μm, which helps to extend the life cycle of the cylinder, and reduces the wear and tear of the seal, The maximum inner diameter of the cylinders produced by our factory reaches 1000mm, with maximum buffing reaching ID length 13000mm.
