Professional Hot Tapping & Line Stop Services
Barnard EMC, Inc. provides safe, precise hot tapping and pipeline isolation services for natural gas, water, sewer, steam, chemical, and other pressurized systems.
Complete Pipeline Modification & Isolation Solutions
Pipeline systems often require tie-ins, repairs, upgrades, or rerouting. Our specialized hot tapping and line stop procedures allow this work to be completed while systems remain operational.
Barnard EMC, Inc. combines certified personnel, industry-approved equipment, and strict regulatory compliance to ensure every project is performed safely and efficiently.
Our hot tapping and line stop services are commonly used for system expansions, valve replacements, emergency repairs, rerouting projects, and infrastructure upgrades across gas, water, sewer, and industrial process piping systems.
Our Services
Hot Tapping
Hot tapping allows new connections to be installed on live, pressurized pipelines without shutting down service. This method is ideal for system expansions, branch connections, instrumentation additions, and infrastructure upgrades.
All hot taps are performed using engineered fittings and industry-approved equipment designed for live, pressurized systems.
Applications Include:
• Natural gas distribution systems
• Water transmission lines
• Sewer force mains
• Steam and condensate systems
• Industrial process piping
Line Stops (Stop Offs)
Line stopping — also referred to as stop offs — provides temporary isolation of a section of pipeline to allow repairs, valve replacements, relocations, or maintenance. This controlled isolation prevents service disruption to the remainder of the system.
Line stopping is often used in conjunction with hot tapping to create a controlled work zone within active pipeline infrastructure.
Common Uses:
• Valve replacements
• Emergency repairs
• Pipeline rerouting
• Tie-ins to existing infrastructure
Thru-Valve Taps
Thru-valve tapping allows tapping operations to be performed directly through an existing valve, providing additional operational control and flexibility during live system modifications.
Top Stops
Top stop procedures provide efficient isolation when removing or replacing valves on active systems. This method minimizes downtime while maintaining safe operating conditions.
Wet Tapping
Wet tapping is used for pressurized liquid systems where shutdown is not feasible. Our crews perform controlled taps to maintain flow while modifications are completed safely.
