Frequently Asked Questions

Q: What is the difference between welded and seamless stainless steel pipes?

Welded pipes are formed from strips and longitudinally welded, ideal for general use. Seamless pipes are produced from hollow billets, offering higher strength and reliability for high-pressure environments.

Q: Which grades of stainless steel are available for these pipes?

We offer Grade 304/304L for general corrosion resistance and Grade 316/316L for enhanced resistance to chlorides and marine environments.

Q: How are the pipe dimensions determined?

Dimensions are nominated by the outside diameter via NPS (imperial) or DN (metric) designators, with wall thickness determined by the schedule number (e.g., Sch 10S, 40S, 80S) per ASME B36.19.

Q: Can you provide pipes with a decorative finish?

Yes, we can supply stainless steel pipes with an abrasive polished finish, specifically designed for high-end architectural and decorative applications.

Q: What standards govern the manufacturing of your austenitic pipes?

Our austenitic pipes are manufactured according to ASTM A312M (Standard) and ASTM A358M (for large diameters).

Q: How do I order non-standard pipe sizes or combinations?

For non-standard requirements, please contact our nearest Service Centre. We will utilize our global supply network of mills and stockists to source the exact specifications you need.
