Frequently Asked Questions

Q: What is the difference between API 5L PSL1 and PSL2?

PSL1 is suitable for general applications, while PSL2 has more stringent requirements for chemical composition, mechanical properties, and mandatory testing, making it ideal for high-pressure or critical environments.

Q: Which coating is best for underground pipeline installation?

For underground use, we highly recommend 3PE (3-layer polyethylene) or FBE (Fusion Bonded Epoxy) coatings as they provide superior moisture barriers and corrosion protection.

Q: Can you provide pipes with specific wall thicknesses like SCH80?

Yes, we offer a wide range of wall thicknesses including STD, SCH40, XS, and SCH80 to meet various pressure ratings and structural requirements.

Q: What are the available diameter ranges for your seamless steel pipes?

Our current production range for seamless steel pipes spans from 1/2" up to 24" outer diameter (OD).

Q: Do you offer custom length cuts for large projects?

Yes, we provide both fixed length (up to 12m) and random length options to minimize waste and optimize your logistics.

Q: Are these pipes suitable for transporting petroleum and natural gas?

Absolutely. Our API 5L pipes are specifically engineered for the oil and natural gas industry to handle the chemical and pressure demands of petroleum and gas transport.
