Dear Gurunath,
You have not mentioned to which standard/code that the valve is manufactured, however para 2.6 of ASME B 16.34 permits the multiple grades marking of more than one specification or more than one grade of a specification provided conditions satisfying the requirements of para 4.2.8, and 5.2.2 together with the pressure – temperature rating requirements of the grades are fulfilled. You can refer to this.
Regards,
MANIVANNAN.

Dear Experts,--Dear All,We are having valve with body material requirement as A351 CF8M but we have got a body which is dual certified for A351 CF3M as well as CF8M & it is embossed on the body as A351 CF3M / CF8M.Problem here is TPI is telling us client requirement is A351 CF8M only, so body should be embossed with only A351 CF8M so grind CF3M embossing on the body of all the valves.Kindly please help me with code reference's if available regarding dual certification & acceptable clause. Else please give more information(picture) regarding dual certification & how it came into practice.Thanks in advance for your valuable time.ವಂದನೆಗಳೊಂದಿಗೆ / Best regards,Gurunath Hanamar
