Permanent Steel Manufacturing Co., Ltd. offers a broad catalogue of seamless pipes that includes carbon‑steel, stainless‑steel 304, stainless‑steel 316 and galvanised variants. The pipes are supplied with outer diameters from 21.3 mm to 508 mm and wall thicknesses ranging between 2 mm and 50 mm. All sizes are produced according to ASTM, API 5L and DIN standards, providing a consistent basis for international projects.
The carbon‑steel option follows the same grade system as the company’s other product lines, while the stainless‑steel 304 and 316 grades deliver enhanced corrosion resistance for chemical‑process and food‑handling environments. Typical tensile strength for stainless‑steel 304 is around 520 MPa and for 316 about 560 MPa, both of which exceed the requirements of most water‑transmission and marine applications. Galvanised pipe receives a zinc coating that meets standard hot‑dip specifications, offering additional protection against atmospheric corrosion.
Clients such as petrochemical plants, water‑utility companies and heavy‑fabrication workshops source these pipes for high‑pressure pipelines, structural frameworks and heat‑exchanger tubing. Shipments are normally arranged in standard 20‑foot containers or as bulk loads, with pricing expressed per metric ton. The public listing does not specify minimum order quantities, lead times or Incoterms; interested buyers should request those details directly from the supplier. Payment conditions are not listed and should be clarified during negotiation.

Importers should first confirm that the pipe dimensions, material grade and applicable standards (ASTM, API 5L, DIN) are documented in a mill test report. Request certificates that verify the stainless‑steel chemical composition and the galvanised coating thickness where relevant.
Logistical arrangements are typically based on 20‑foot container loads or bulk shipments. Because the listing does not provide Incoterms, lead‑time estimates or payment conditions, these details must be negotiated directly with the supplier. Common payment methods include T/T against documents or a confirmed LC, but the final terms should be recorded in the purchase contract.
Quality control commonly involves hydrostatic pressure testing, ultrasonic thickness verification and surface‑finish inspection. Importers are advised to engage an independent inspection agency to review the mill test report, perform a hydrostatic test and confirm the coating weight for galvanised pipe before shipment. Ensure that the shipping documentation includes a certificate of conformity and a detailed packing list that records the outer‑diameter and wall‑thickness of each bundle.
