Number/ Use of Golden welds
Number/ Use of Golden welds
(OP)
Gentleman,
There is the existing pipeline 8", class600, design pressure 43 barg, design temp -95 C, follow code ASME B31.3. The static mixer will be added to this existing pipeline.
The hydrostatic test seem impraciable due to operation point of view (to avoid freezing of left moisture)
Can I treat those TWO modified joints as golden weld/closure weld?
Does code limit quantity of golden weld joints in one pipeline?
Does code limit number of time for golden weld on one line if there is the modification again?
Thanks for any advise.

You should refer to API 570. The phrase "principles of ASME B31.3" has been employed in API 570, rather than "in accordance with ASME B31.3".
