FAQ
Q: Is TP316L worth the extra cost over TP304L?
A: If your environment contains chlorides (like seawater or salt air), TP316L is essential due to its molybdenum content, which prevents pitting corrosion.
Q: What's the difference between seamless and welded pipes?
A: Seamless pipes offer uniform wall thickness and higher pressure ratings, while welded pipes provide cost-effective solutions for standard pressure applications.
Q: Can you provide custom lengths?
A: Yes, we manufacture pipes in both standard and custom lengths according to your project specifications.
Q: What testing documentation do you provide?
A: We supply mill test certificates, chemical analysis reports, and mechanical property test results with every shipment.
