DIN 7391 Seamless Stainless Steel Tube
The DIN 7391 Seamless Stainless Steel Tube is produced by ARK Steel Tube Company and meets the DIN 7391 standard for precision engineering. The tube is made from stainless steel grades 304 and 316 and is manufactured by cold drawing and cold rolling, delivering a uniform wall thickness and a smooth surface finish. Size specifications listed are outer diameters from 6.0 mm to 650.0 mm, wall thicknesses from 1.0 mm to 65 mm, and a maximum length of 12 000 mm.
Typical industry practice for DIN 7391 tubes includes an outer‑diameter tolerance of ±0.2 mm and a wall‑thickness tolerance of ±0.1 mm, which ensures dimensional consistency for hydraulic and pneumatic systems. Surface roughness is usually Ra ≤ 0.8 µm for stainless grades, supporting high‑pressure applications. The tubes are often supplied in bundled packs on pallets to facilitate handling and storage.
These tubes are bought by OEMs in the automotive, hydraulic, and machinery sectors that require corrosion‑resistant piping with tight dimensional control. ARK Steel Tube Company mentions export experience to markets such as the USA, Europe and Asia, and accepts T/T payment terms. Importers should confirm the exact length, diameter and grade required for their project, as well as any required testing or certification before finalising the order.

Sourcing DIN 7391 Seamless Stainless Steel Tube from ARK Steel Tube Company - China Import Guide
Prior to ordering, request the mill test report and any applicable certifications (e.g., ASTM or DIN conformity) to confirm that the tube meets your material and dimensional requirements. Verify the grade, diameter, wall thickness and length against your engineering drawings, and ask the supplier to provide a drawing package if needed.
Logistics for these tubes usually involve loading from a Chinese port, with the most common Incoterms being FOB or CIF. Confirm the exact port of loading, the expected lead time based on your order size, and the payment method - the supplier lists T/T as the standard term. Discuss freight options early to avoid unexpected delays or extra handling costs.
Quality assurance should include dimensional inspection, wall‑thickness measurement and a pressure‑test where applicable. Arrange a pre‑shipment inspection by an independent inspection agency, and request the final packing list, certificate of origin and the material test report. These documents will support customs clearance and downstream quality verification.
