Frequently Asked Questions
Q: What is the difference between Sch40 and Sch80?
A: Sch40 is standard wall thickness, while Sch80 is extra-strong (XS) with thicker walls for higher pressure applications. Both are available in this product range.
Q: Are these pipes suitable for outdoor use?
A: Yes, 304 stainless steel offers good corrosion resistance in most outdoor environments. However, for highly corrosive conditions (e.g., coastal areas), we recommend 316L grade.
Q: Can you provide custom lengths?
A: Absolutely. We can cut pipes to your specified lengths, including random lengths and fixed lengths, with minimal order quantity.
Q: What certifications do you have?
A: Our company is ISO9001 certified. We also provide mill test certificates (MTC) as per ASTM A312 upon request.
Q: Do you offer surface treatment like polishing?
A: Yes, we offer pickling, passivation, and polishing services. Please specify your requirements when ordering.
Q: What is the typical lead time?
A: For standard sizes, lead time is 15-20 days after order confirmation. Custom orders may require 25-30 days.
Q: Can you ship to my country?
A: We export to over 30 countries worldwide. Our main shipping port is Qingdao, and we can arrange FOB, CIF, or DDP terms.
Q: Are these pipes seamless or welded?
A: These are welded pipes manufactured using high-frequency welding. They offer excellent dimensional accuracy and cost-effectiveness compared to seamless.
