Frequently Asked Questions

Q:What is the product?

A:It is a duplex stainless steel pipe with high strength and corrosion resistance. The balanced microstructure gives you both toughness and durability in corrosive environments.

Q:S31803 vs 316L, what is the difference?

A:S31803 has higher strength and better resistance to chloride corrosion. You can use thinner walls while maintaining the same pressure rating, reducing material costs significantly.

Q:Where is S31803 used?

A:Oil & gas, offshore, and chemical industries. Anywhere you face aggressive corrosive conditions or need high strength-to-weight ratio.

Q:Can you provide custom lengths?

A:Yes. We supply random length, fixed length according to your drawings, or U-bent configurations for heat exchangers.

Q:What documentation do you provide?

A:You receive complete traceability: Material Test Certificates (EN 10204 3.1 or 3.2), Third Party Inspection reports, welding procedure specifications, and ultrasonic or radiographic test reports.
