I already know the answer to this but, it worth throwing it out there for everyone. In Alberta I see tie-ins shown at fittings all the time on piping drawings. I actually learned that way if I’m truthful. I know now years later through field experience the rule of thumb is actually to be a min 1″ or 4 times Wall thickness away from a weld. Other issues like equipment/work space access, safety etc also play important roles as well. Can you guys give us some good reasons why it is better to cut a pipe before your fitting weld a few inches away on the pipe rather than at the fitting weld itself? Alot of people don’t understand why this is done.
Thanks guys
