Bolting

Online’s skilled technicians perform a variety of techniques including:

Bolt Tensioning – Tightening threaded fasteners uniformly using advanced hydraulic technology. This method ensures the compressibility required by the gasket manufacturer to achieve joint integrity resulting in no leakage. Also, the tensioning method reduces the time required to achieve the final torque value of the joint.

Torque Tightening – using a range up to 80,000 Ft. Lbs. of the latest pneumatically energized hydraulic torque wrenches.

Fastener Breakout – using a range up to 80,000 Ft. Lbs. of the latest pneumatically energized hydraulic torque wrenches in conjunction with standard pneumatic impact wrenches to disassemble bolted joints.

Hot Bolting – On-line torquing of components to prevent or stop leakage.

Engineering Support – providing written torque procedures and bolting patterns specifically designed for a specific application.

With an ever increasing industrial emphasis on safety, economics, and protection of the environment from fugitive emissions has made the elimination of leaks from bolted assemblies a high priority. Online’s bolting techniques are vital in maintaining the optimum performance from repeatable bolt loads and pressure containing joints allowing Online to provide turn-key repair services including: break out, machining, gasket replacement, and reassembly.
