Our mission is to develop creative products to customers with a good experience for Honed Steel Pipes, ST52 Cold Drawn Hydraulic Cylinder Rod, Induction Hardened With QT Piston Rods. From design to production, to shipment, we will serve every procedure carefully to ensure that the goods are delivered according to the quality and quantity. We can supply custom service too such as Logo, custom size, or custom merchandise, etc that can according to customer's requirement.

Hydraulic cylinder honed tubes is a kind of pipe which the inner hole of cold drawing pipe is machined by honing head with the high speed grinding process, so that the inner hole achieves the tolerance dimension and surface roughness requirements required by customs. They are used in hydraulic cylinders and air cylinders directly and widely used in engineering machinery, metallurgical machinery, mining machinery, road construction machinery, textile machinery and other industries.

Features:

We are a manufacture which can supply products and services from raw material to hydraulic cylinders and machines, including acid pickling, parkerising, saponification, cold drawing, quenching, stress annealing, honing, welding, precision machining and other processing.
