Bolt Torquing

[VanniDiCarlo]

Hi there
any body can share a specification for Bolt Torquing, including the values? I have to prepare a specification.
Thank You

From my experience, this is a far too simple question to ask. You need to be more specific in terms of service, material and temperature applications. What you'd do for regular refinery piping and steam piping is vastly different. If it it just standard refinery piping, follow the methods in either ASME PCC 1-10 or API 6A. Either of those is the basis for refinery piping that I've worked on.

Developing a spreadsheet isn't too difficult. The method is explained fully.
