FAQ
Q1: How does 316L differ from 316Ti stainless steel pipes?
A: 316Ti adds titanium stabilization to prevent sensitization during welding, ideal for 600–800°C (1,112–1,472°F) applications.
Q2: What welding methods ensure leak-proof joints?
A: Use orbital TIG (GTAW) with ER316L filler and argon back purging for sanitary-grade welds.
Q3: Are pipes certified for offshore oil platforms?
Full compliance includes:
- NACE MR0175/ISO 15156
- DNV-OS-F101
- ASME B31.3 Process Piping
Q4: What’s the minimum order quantity (MOQ)?
Standard stock: 1 ton MOQ.
Custom sizes/tempers: 5 tons MOQ (lead time 35 days).
