Frequently Asked Questions

What is Duplex 2507 stainless steel?

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. It is designed for applications requiring exceptional strength and corrosion resistance.

What are the main advantages of using super duplex steel pipes?

They offer significantly higher strength than austenitic stainless steels, excellent resistance to localized corrosion (pitting/crevice), and high resistance to stress corrosion cracking in chloride-bearing environments.

What standards do these pipes comply with?

Our pipes are strictly manufactured according to international standards such as ASTM A312, A269, A815, and others, ensuring 100% compliance and quality.

In which industries are these pipes commonly used?

They are widely used in desalination plants, oil and gas offshore platforms, chemical processing, marine applications, and pulp/paper manufacturing.

What surface treatments are available?

Options include annealing and pickling, matt finish, satin finish, mirror finish, and wire drawing (hairline finish) depending on your application needs.

What is the typical tolerance for these tubes?

We maintain a high precision tolerance of +/-0.05mm for our seamless tubes, ensuring accurate fit and performance in complex systems.
