Heat input for welding in pipelines in service
(OP)
What shell be the maximum heat input for welding fittings to pipelines in service? Is it the ones specified in the qualification welding procedure?

In looking at the tank hot-tap procedures, I notice they limit the tank stress when welding is done and prohibit hot tapping tanks under various conditions. I would assume there are similar restrictions in pipe or maintenance codes or company procedures for pipeline work.
