Advantages of Duplex Stainless Steel Check Valves:

1. The yield strength of the duplex steel check valve is more than double that of ordinary austenitic stainless steel, and it has sufficient plasticity and toughness required for forming. The wall thickness of the storage or pressure vessel made of duplex stainless steel is reduced by ordinary austenitic stainless steel. 30-50%, which is conducive to reducing costs.

2. The duplex steel check valve has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has a higher resistance to stress corrosion cracking than austenitic stainless steel, especially in the environment containing chloride ions. Among them, stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.

3. Duplex steel check valves are used in many media. The most commonly used 2205 duplex stainless steel is better than ordinary 316L austenitic stainless steel in corrosion resistance, while super duplex stainless steel has extremely high corrosion resistance. It can even replace high-alloy austenitic stainless steels and even corrosion-resistant alloys.

4. Duplex steel check valve has good local corrosion resistance. Compared with austenitic stainless steel with equivalent alloy content, duplex stainless steel has better wear resistance and fatigue corrosion resistance than austenitic stainless steel.

5. The linear expansion coefficient of dual-phase steel check valve is lower than that of austenitic stainless steel, which is close to that of carbon steel. It is suitable for connecting with carbon steel and has important engineering significance, such as the production of composite plates or linings.

6. Duplex stainless steel check valve has higher energy absorption capacity than ordinary austenitic stainless steel no matter under dynamic load or static load condition, which has practical application value for dealing with emergencies such as collision and explosion. .
