ERW Steel Pipe JIS G3444
ERW Steel Pipe JIS G3444 from Threeway Steel Co., Ltd. is manufactured to the Japanese Industrial Standard for electric resistance welded carbon steel tubes, with grades ranging from STK 290 to STK 490. The outer diameter spans 33.4 mm to 660 mm, wall thickness from 2.1 mm to 22 mm, and standard lengths range from 0.8 m to 18 m. These pipes are produced using continuous welding processes that ensure consistent seam integrity and dimensional accuracy, meeting the mechanical requirements of JIS G3444 without additional heat treatment.
The material composition conforms to carbon steel with specified manganese, silicon, and carbon limits as defined in JIS G3444. Grades such as STK 400 and STK 490 offer increasing yield strength, suitable for load-bearing applications. Typical industry practice includes surface treatment for corrosion resistance, though no coating is specified in the base standard. Pipes are commonly supplied in plain finish or with protective oil coating to prevent rust during transit. Standard tolerances for OD and WT follow JIS G3444 limits, typically ±1% for diameter and ±10% for wall thickness.
These pipes are widely used in scaffolding, fencing, handrails, structural frameworks, and fluid transport systems in construction and industrial projects. Buyers include engineering contractors, scaffolding distributors, and infrastructure suppliers in Southeast Asia, the Middle East, and Africa. Trade terms are typically FOB China port, with minimum order quantities negotiated per batch. Packaging is usually in bundles secured with steel straps, labeled with grade, size, and heat number. Certifications such as mill test reports are available upon request.

Sourcing ERW Steel Pipe JIS G3444 from Threeway Steel Co., Ltd. - China Import Guide
Before ordering, verify the exact grade (STK 290 to STK 490) and confirm the mill test report includes chemical composition and mechanical test results for the specific heat batch. Request documentation of the welding process used and whether non-destructive testing was applied to the seam. Do not accept generic certificates; ensure each batch has traceable documentation linked to the shipment. Confirm the supplier does not substitute lower-grade material without notice.
Confirm the Incoterms, typically FOB China port, and whether loading charges are included. Lead time is usually 20 to 35 days after deposit, depending on production scheduling and port availability. Payment terms are commonly 30% advance, 70% against copy of shipping documents. Buyers should clarify container loading method, whether pipes are stacked or strapped, and if protective covering is applied. Request a packing list matching the MTR batch numbers.
Upon arrival, inspect for surface defects such as cracks, dents, or excessive rust. Measure wall thickness at multiple points using a digital caliper to verify compliance with ±10% tolerance. Check that labels match the MTR and that bundles are not mixed by grade. Request third-party inspection if the shipment exceeds 10 metric tons. Retain samples from each batch for potential future testing. Ensure all documentation is in English and matches the purchase order specifications.
