Frequently Asked Questions (FAQ)
-
Q: What is the difference between ASTM A106 Gr.B and API 5L Gr.B?
A: Both are carbon steel pipes, but ASTM A106 is specifically designed for high-temperature service, while API 5L is for line pipe transportation. A106 Gr.B has tighter chemical and mechanical requirements for elevated temperature use. -
Q: Can you provide heat treatment certificates?
A: Yes, we can provide a mill test report (MTR) including chemical composition, mechanical properties, and heat treatment details upon request. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 10 tons for standard sizes, but we can negotiate smaller quantities for trial orders. -
Q: Do you offer third-party inspection?
A: Absolutely. We welcome inspections by SGS, BV, or any other accredited third-party agency at your cost. -
Q: How long does delivery usually take?
A: For standard sizes, delivery is 15–20 days after deposit. For custom sizes or coatings, it may extend to 30–45 days. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and sometimes D/P for established clients. -
Q: Is the pipe suitable for sour gas service?
A: Standard ASTM A106 Gr.B is not specifically rated for sour service (H2S). For sour environments, we recommend NACE MR0175 compliant materials. Please contact us for suitable alternatives. -
Q: Can you supply pipes with 3LPE coating?
A: Yes, we offer 3-layer polyethylene (3LPE) and fusion-bonded epoxy (FBE) coatings as optional extras. Please specify your requirements.
