Frequently Asked Questions

Q:What is the product?

A:It is a super duplex stainless steel pipe built for uncommon erosion resistance and tall mechanical quality. The adjusted ferritic-austenitic microstructure gives predominant execution in forceful situations compared to standard stainless steels.

Q:S32750 vs S31803, which is better?

A:S32750 offers altogether higher quality and way better resistance to setting and cleft erosion than S31803. Whereas S31803 works well in modestly destructive conditions, S32750 exceeds expectations in the most requesting applications including tall chloride concentrations, raised temperatures, or acidic media.

Q:What are the typical applications?

A:The essential employments incorporate seaward oil and gas stages, seawater desalination offices, chemical preparing plants, marine designing frameworks, mash and paper generation gear, and any environment where standard duplex grades do not give satisfactory erosion protection.

Q:Can you provide custom lengths and finishes?

A:Yes, we accommodate random lengths, fixed lengths, or U-bent configurations. Surface finishes include bright annealed and pickled options. Contact us to discuss your specific requirements.
