Frequently Asked Questions
-
Q: What is the difference between Seamless and ERW pipe?
A: Seamless pipe is manufactured without a welded seam, making it stronger and more suitable for high-pressure applications. ERW (Electric Resistance Welded) pipe has a longitudinal weld. Our 8-inch Schedule 40 pipe is seamless, ensuring reliability under stress. -
Q: Do you provide a Mill Test Report (MTR) with every order?
A: Yes, every pipe we ship comes with a Mill Test Report that includes chemical composition, tensile strength, yield strength, and other mechanical properties. It is traceable to the heat number. -
Q: What standards does this pipe comply with?
A: Our pipe meets ASTM A106, API 5L, and ASME B36.10 standards. It is manufactured in accordance with ISO9001 quality management system. -
Q: Can I get custom lengths or end preparations?
A: Absolutely. We can supply pipes in custom lengths (e.g., 5.8m, 11.8m) and with plain ends, beveled ends, or threaded ends upon request. Please specify your requirements. -
Q: What is the typical lead time for an order?
A: For standard sizes like 8-inch Schedule 40, lead time is usually 7–15 days depending on quantity. Custom orders may take longer. We offer fast shipping to global destinations. -
Q: Is the pipe suitable for underground or outdoor use?
A: Yes, with proper surface treatment (e.g., black painting or varnish), it can be used outdoors. For buried applications, we recommend additional anti-corrosion coating such as 3LPE or FBE (available upon request). -
Q: What is the warranty coverage?
A: We provide a 1-year warranty against manufacturing defects. This includes issues like cracks, leaks, or dimensional non-conformance found during proper use. The warranty does not cover damage caused by improper installation or external factors. -
