NC Pipe Freeze recently received a call from an area hospital for an immediate freeze plug application. The project initially called for a single ½" pipe isolation to change out a rotten ½" pipe. Upon arrival the NC Freeze techs discovered instead the necessary repair would require a double simultaneous freeze plug on a 2 ½" chill water pipe. With our large inventory of CRYO-LATOR® Chambers and equipment this on-site project scope change was no problem. Please take a moment to review the below thumbnail photos from that recent project. And as always call us if you have any questions and thank you for taking the time on our site.

This project was completed with a set of SC-200 CRYO-LATOR® Chambers using CRYOSTOP Positive Seal Tape guaranteeing no refrigerant leakage during the critical "open line" freeze plug process.

Both SC-200 Chambers set up and ready to establish the double simultaneous freeze plugs. Note the 90° vent stacks. This was done as a safety precaution to minimize the distribution of LN2 vapors to the overhead floors.

The freeze plugs were established in about 15 minutes and ready for the ½" to be changed out.
