Heat treatment, hydrostatic testing, rework

Thread Content

There is a boiler unit that was subjected to heat treatment followed by a hydrostatic test, during which leaks were detected. Is heat treatment required again after welding to repair those leaks? Or what are the conditions under which patch welding does not affect the previous heat treatment?

After welding, local heat treatment is carried out in accordance with the specification requirements, and a hydrostatic test is conducted after the heat treatment.

It can be implemented in accordance with the requirements of clauses 7.4.3 and 7.4.4 of GB/T 150.4-2011
