The Gangline

The Gangline Temporary Pipe Restraint System (Gangline™) is a professionally-engineered series of Gangline Restraints designed to limit the movement of pipes in a Temporary Pipeline (Pipeline) in the case of catastrophic failure.

The Gangline is designed specifically for 1502 style Hammer Union pipes with nominal inside diameters of 2 to 3 inches. It is designed for temporary flowlines with recommended maximum pressure up to 15,000 psi (larger Gangline systems are available upon request for pressure pumping jobs in 4″ up to 15,000 psi).

The Gangline has three sizes, each designed to fit a specific combination of inside diameters and pressures of the temporary pipe. It works on flow lines, frack lines, temporary pipelines, frack irons, 1502 irons, swivels, Chicksans® and flow irons. The Gangline also includes assemblies to restrain swivels or Chicksans® within a Pipeline. When correctly installed, the Gangline will restrain each side of the Union of each Pipe Segment through the entire linear series of a Pipeline.

The Gangline consists of only two parts: either restraints and carabiners or restraints and shackles. It offers a lightweight, high-strength installation solution for your peace of mind.
