JIS G 3454 STPG370 Carbon Seamless Steel Tubes
The JIS G 3454 STPG370 carbon seamless steel tubes offered by Botop Steel Pipe CO., Ltd are manufactured to the Japanese JIS G 3454 standard. They are produced from carbon steel grades STPG370 and STPG410 with a maximum carbon content of 0.25 % and manganese between 0.30 % and 0.90 %. Outer diameters are available from 15.0 mm up to 660 mm and wall thicknesses range from 2 mm to 50 mm. Each tube is supplied in a standard 6 m length, with custom lengths cut on request.
The chemical composition ensures adequate strength for high‑pressure service in oil‑and‑gas transmission, petrochemical and mechanical engineering fields. Typical industry practice applies normalising heat treatment and a surface finish that meets the JIS tolerance of ±0.2 mm on diameter and ±0.1 mm on wall thickness. End configurations include plain and beveled ends, allowing flexible installation without additional machining. The product is shipped in bundles that respect the minimum order quantity of five tons per order.
Importers commonly use these tubes for pipelines, pressure vessels and structural frames, where dimensional stability and pressure rating are critical. Trade terms are negotiated per order; buyers should confirm incoterms, payment method and lead time directly with Botop Steel Pipe. The supplier’s address in Cangzhou, Hebei provides a logistical hub for sea freight from nearby ports such as Tianjin. Verify the product certification and request a mill test report before finalising purchase.

Sourcing JIS G 3454 STPG370 Carbon Seamless Steel Tubes from Botop Steel Pipe CO., Ltd - China Import Guide
Before placing an order, importers should request the mill test report, verify compliance with JIS G 3454, and confirm that the chemical composition matches the STPG370 or STPG410 grade. Checking the supplier’s business licence and any available quality certificates helps reduce the risk of non‑conforming material. It is also advisable to request a sample cut to confirm dimensional accuracy before committing to the full volume.
Logistics for steel tube shipments from Cangzhou typically involve loading at the Tianjin port or other nearby facilities. Buyers need to agree on Incoterms such as FOB or CIF, and clarify the expected lead time, which commonly ranges from four to six weeks after order confirmation. Payment terms are usually negotiated as a letter of credit or telegraphic transfer, but the exact conditions should be confirmed with Botop Steel Pipe before signing the contract.
Quality assurance commonly includes third‑party inspection at the factory, visual checks for surface defects, and dimensional verification against the agreed tolerances. Importers often require a certificate of conformity and a coating inspection report for the ends. Ensuring that all documentation, including the mill test report and any relevant certificates, accompanies the shipment will streamline customs clearance and downstream quality checks.
