Standards and specifications for selecting safety valve springs
Thread Content
The design institute specified 50CrVA for the high-pressure steam springs, with steam parameters of 4.6 MPaG and 440°C. I checked Baidu Baike; 50CrVA is suitable for operating conditions below 300°C. I also checked standards such as GB/T1222, GB/T1239.6, and GB/T12243, all of which mention the temperature requirements for 50CrVA. May I ask which standard provides the specifications for selecting the temperature of springs? Thank you!
