RE: Steam Sample coolers

Hi!

Looking for an advise based upon your personal experience and sound references. We are planning to hot tap and Hot & Stopple (One Location Hot tap to install a jump-over line and down stream of this Hot tap, put a stopple for the installation in line isolation valve). The run pipe is 42 inch and the Hot tap will be 18 inch. Now the question is as follows; - Due to lack of confidence on the quality of welders we have almost finalized the Mechanical Tee to avoid either burn through or hydrogen cracking.

How many of you guys will approve mechanical tee, in place of welding tee? What are credibility and Integrity issues related to mechanical tee as compared to welding tee?

Regards
