Hot Tap & Line Stopping Services

Companies are often required to make modifications to their existing process piping systems and containment tank systems for reasons of expansion or maintenance. Historically, this has required shutting down a portion of the system and purging the line to ensure a safe connection. Hot tapping & Line Stopping is a cost & time efficient alternative procedure of making connections to in-service piping systems, tanks and vessels.

Safe from start to finish, Red Flame Industries’ is committed to risk management, through engineering controls, uncompromising standards, and complete hot tap & line stopping services, with custom designed solutions.
