Buy & Import Seamless Steel Pipes Hydraulic Cylinder Tubes from Yishui Guangju Hydraulic Cylinder Manufacturing Co.,LTD - Wholesale Supply

The item is a seamless carbon‑steel tube intended for hydraulic cylinder assemblies where high precision is essential. It is offered in outer diameters from 30 mm to 250 mm, wall thicknesses ranging 3 mm to 35 mm, and standard lengths of 3 m to 5.8 m. Dimensional control follows an h8 tolerance and straightness is limited to 0.5 mm per 1000 mm. The material grades supplied include ST52, ST37, 16Mn and Q345, all meeting DIN, GB, ASTM and API requirements.

In the hydraulic industry, these grades are typical for components that must endure cyclic loading and high pressure, with ST52 providing superior tensile strength. The internal surface is usually honed to a roughness of Ra 0.2 µm, which is standard for reducing fluid resistance. Optional surface treatments such as oil‑based paint, galvanising or chrome plating can be applied to enhance corrosion resistance. Typical pressure capabilities reach 250 bar for lower grades and exceed 350 bar for high‑strength alloys.

Primary users include manufacturers of agricultural machinery, construction equipment and large‑scale fluid‑power systems that require tight bore tolerances. The tubes are packed in bundled units with protective plastic caps and sealed bags, and the supplier states a standard delivery period of 30 days. Payment terms are T/T or L/C, with the possibility to negotiate FOB, CIF or other Incoterms according to the buyer’s freight strategy.
