Hot tapping a chilled water system
Hot tapping a chilled water system
(OP)
Looking for info, pitfalls or ? in determining a job involving tapping an 8" supply and return from a central plant for a small job. Approx 2" will be used. Capacity is not an issue.
I am just looking for info like,,, "better have lots of buckets nearby" or need 3' clearance around each pipe. You know if you have done it before. So as I typically read the questions and answers here, I ask you guys.
Thanks,

The most important bit of advice that I can offer is to find a mechanical contractor who has a good deal of experience with hot taps. If they have the proper equipment and know how to use it, hot taps are a great way to create a new branch connection, with virtually no loss of system fluid. If they are trying to get by with a homemade hottap rig, find someone else.
Of great importance is retrieval of the hole saw plug. Make sure that after they drill the pilot hole, they use a spring loaded hole saw arbor, which will capture the plug. Also spec that they turn over the plug to you, as proof that it's not floating through your system. Make sure that they use a 2" weld-o-let, and a 2" full-port ball valve. And yes, the equipment will need about 3' of clearance.

Nevertheless, the number of successes and the time they saved makes hot tapping a realistic option, even for me. I just accept that it is not risk free (but what is?).

You posted a question on the end of an old topic.
You may want to repost as a new thread.
As to your question, I only can offer this; Lots of surface area. Good luck.
