Material selection for high-pressure valves
Thread Content
This post was last edited by kareale88 on 2019-4-9 14:48. In the chemical industry, what are the common materials used for high-pressure valves? For example, what materials are generally used for stop valves of PN150 and above? Is 2205 or above sufficient, or will 316L meet the requirements? Seek guidance from experts
If pipes with a pressure rating of >10 MPa are classified as high-pressure pipes and valves, then valves with a pressure rating of 600 Lb or higher can all be considered high-pressure valves. There are many options available for the material of the valve body; these can include forged or cast valves. The possible materials include ASTM A105, ASTM A216 WCB, ASTM A182 F304, ASTM A182 F304L, ASTM A182 F316, ASTM A182 F316L, ASTM A351 CF8, ASTM A182 F11, ASTM A182 F22, ASTM A217 WC6, and more
Okay, thank you. Regarding high-pressure valves, are there many options available for things like the valve disc and valve stem?
The valve stem is generally made of forged materials; common choices include ASTM A182 F6a CL2+ with hardening treatment, A182 F304, and A182 F316. Common materials for the valve disc include ASTM A276 420, A182 F304, and A182 F316
