Question 1

What are Super Duplex Valves used for?

Accepted Answer

Super Duplex Valves are widely used in offshore, oil & gas, marine, desalination, and chemical processing industries. They are specially designed to handle high pressure and highly corrosive environments, particularly where exposure to seawater and chlorides is common.

Question 2

What grades are available in Super Duplex Valves?

Accepted Answer

The most common grades are UNS S32750 (F53) and UNS S32760 (F55). Both grades offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, with F55 providing slightly higher strength and corrosion resistance.

Question 3

Why choose Super Duplex Valves over standard stainless steel valves?

Accepted Answer

Super Duplex Valves provide nearly double the strength of standard austenitic stainless steels like 304 and 316. They offer superior resistance to chloride induced corrosion, making them ideal for aggressive industrial and marine environments.
