Sourcing 631 Stainless Steel Pipe from Jiangsu Steel Group Co., Ltd. - China Import Guide
Before ordering, verify the heat treatment condition (TH, RH, or CH) and confirm it aligns with your application’s mechanical requirements. Request third-party inspection reports or mill certificates to validate the material grade and properties. For aerospace or nuclear use, ensure the pipe meets additional industry-specific standards beyond ASTM A565.
Logistics should be confirmed in detail: the supplier offers FOB Shanghai or CIF terms, so clarify port of discharge, shipping method, and insurance coverage. Lead times vary from 7 to 30 days based on quantity, so plan for production schedules and potential delays. Packaging options include plywood cases, wooden pallets, or bundles, all designed for seaworthy transport.
Quality checks should include dimensional verification (outer diameter, wall thickness, length) and surface finish inspection using a profilometer for Ra values. For critical applications, conduct non-destructive testing (NDT) such as ultrasonic or eddy current testing to detect subsurface defects. Ensure all documentation, including MTCs and compliance certificates, accompanies the shipment.
