Hot Tap
MPR's hot taps allow drilling and cutting into pressurized piping or tanks, and have been                           used extensively for making branch connections into operating heat exchangers, vessels,                        columns, tanks, a pipelines. This procedure is completed in a safe, controlled condition                                and is very cost effective compared to the alternative of a complete shutdown of your system.
