Enlisting all preheat & PWHT requirements
Enlisting all preheat & PWHT requirements
Is there any website having a complete list of all ASME materials with their preheat & PWHT requirements as per all different construction codes?
Re: Enlisting all preheat & PWHT requirements
The charts are readily available to have these temperature ranges however directly looking into the code is recommended.

You can use the following link to know preheat temperature.
I am not sure about the code compliance but a very useful calculator.

ben,
This is a useful one but does not provide the code compliant values for pre-heat & PWHT for all different materials.
As I understand it leads you to the actual requirements (academic) based upon the chemical composition you provide.
Let me know if you find some references, enlisting code values including ASME B31.1, 3 etc.
