Pipeline Hot Tapping & Line Stopping Services

Fairtex provides turnkey hot tapping, line stopping, and in-service pipeline intervention services for oil & gas, power, petrochemical, and industrial process systems. Our solutions enable modifications, repairs, and tie-ins without interrupting live operations.

We support onshore, offshore, and subsea pipeline systems with engineered intervention solutions designed to minimize downtime, maintain operational continuity, and ensure safe execution under pressurized conditions.

Typical applications: live pipeline tie-ins, emergency bypass systems, valve installation, pipeline rerouting, shutdown avoidance, subsea pipeline modification, process piping interventions

What this service covers

Pipeline Hot Tapping Services

Hot tapping operations allow safe connection to live pipelines and vessels without shutdown, enabling modifications, tie-ins, and expansion activities under pressure.

Line Stopping & Line Plugging

Temporary isolation of pipeline sections using line stopping equipment to facilitate repairs, valve replacement, rerouting, or maintenance where no isolation valve exists.

Emergency Pipeline Bypass Solutions

Rapid-response bypass systems designed to maintain flow continuity during emergency repairs, integrity threats, or planned interventions.

Subsea Hot Tap & Line Stop Services

Execution of subsea pipeline interventions including hot tapping and isolation operations for offshore pipeline infrastructure.

In-Service Welding & Fabrication

Qualified in-service welding procedures for hot tap fittings, branch connections, and live system modifications under ASME compliance requirements.

Pipe Freeze & Pipe Plugging Solutions

Controlled isolation methods including freeze plugging and mechanical plugging for temporary shutdown and repair operations.

Valve Installation & System Modification

Installation of valves, fittings, and associated piping modifications on existing pressurized systems.

Pressure & Temperature Critical Interventions

Capability to execute hot tap and intervention works on systems operating up to 5000 PSI and temperatures up to 700°F.
