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.

Line Stop
MPR can perform a single or double line stop to pipes from 1/2" up to 36" in diameter and enable pipelines and plant piping systems to be isolated for repairs or additions without causing an interruption in service or loss of products. Our line stop services are used in petrochemical plants, refineries, power plants, municipal water districts, hospitals, steel mills, and pipeline operating companies.
