The product is a seamless carbon‑steel honed tube designed for hydraulic cylinder and precision mechanical applications. It is supplied in outer diameters from 30 mm up to 250 mm with wall thicknesses between 3 mm and 35 mm. Standard lengths run from 3 m to 5.8 m and the dimensional tolerance is class h8, giving a straightness of no more than 0.5 mm per 1000 mm. The tubes are offered in grades 20‑45#, 16Mn, Q345, ST52 and ST37 and conform to DIN, GB, ASTM and API specifications.
These grades are typical carbon‑steel selections for fluid‑power components, providing a balance of strength and weldability. The honed internal surface normally achieves a roughness of Ra 0.2 µm, which is standard for low‑friction hydraulic flow. Depending on the end‑use, the tubes can be finished with oil‑based paint, galvanising or chrome plating, or left as‑is for further processing. Typical pressure ratings reach 250 bar for the lower 20# grade and increase with higher alloy grades.
Buyers such as automotive OEMs, mining equipment manufacturers and hydraulic system integrators frequently specify these tubes for their durability and dimensional accuracy. Orders are normally packed in bundled sets with plastic caps and protective bags to prevent damage during transit. The supplier states a general delivery window of 30 days, accepts T/T or L/C payments (with a preference for T/T), and can discuss Incoterms such as FOB or CIF on a case‑by‑case basis.

Before placing an order, verify the exact outer diameter, wall thickness and length required, and confirm that the chosen steel grade matches the performance needs of your hydraulic system. Request the mill test report and material certification to ensure compliance with DIN, GB, ASTM or API as appropriate.
Discuss logistics early; the supplier normally quotes a 30‑day lead time and can ship under FOB, CIF or EXW terms. Clarify the Incoterm that best fits your supply chain and confirm the preferred payment method, noting that T/T is preferred but L/C can be arranged.
Arrange a third‑party inspection to check dimensional tolerance, straightness and surface finish before loading. Obtain the final inspection certificate, test reports and packing list to satisfy customs and quality assurance requirements in the destination market.
