Torquing and flange management for mechanical joint integrity

Fairtex provides torquing and flange management services designed to support safe, controlled, and leak-free operation of bolted connections across critical industrial facilities. Our services support pre-commissioning, shutdown turnarounds, maintenance operations, and construction activities within onshore and offshore oil and gas environments.

Using hydraulic torque systems, bolt tensioning equipment, hydrostatic testing tools, and controlled flange management procedures, Fairtex helps maintain mechanical joint integrity across piping systems, wellheads, pressure equipment, manifolds, and rotating machinery. Our experienced technicians support both planned maintenance campaigns and urgent field intervention activities where leak prevention and operational reliability are essential.

Typical applications: LNG facilities, FPSOs, production platforms, refineries, wellheads, subsea systems, BOP stacks, frac trees, manifolds, production trees, pump house flanges, pipelines, bridges, steel structures, and industrial process systems.

What this service covers

Hydraulic bolt torquing and tensioning

Fairtex performs hydraulic bolt torquing, bolt tensioning, and manual torque application for industrial bolted joints requiring controlled preload and uniform gasket compression. Our services support flange connections, pressure vessels, compressors, manifolds, piping systems, and critical process equipment.

Flange management and leak integrity support

We provide flange management services focused on leak prevention, flange alignment, gasket seating verification, and connection integrity restoration. Using hydrostatic test pumps alongside hydraulic torque systems, Fairtex identifies and rectifies leakage paths caused by damaged, loose, or improperly assembled flange connections.

Mechanical joint integrity solutions

Our mechanical joint integrity services include hydraulic nut splitting, flange spreading, bolt replacement support, gasket replacement assistance, and controlled flange separation during maintenance and shutdown activities. Fairtex supports both offshore and onshore maintenance environments requiring safe and reliable bolted joint management.
