Pipeline Clamp
For Long Splits or Extensive Corrosion
Model "PL"

     There is nothing like the Skinner-Seal Pipeline Clamp for long splits or extensive corrosion resulting in a series of pitholes. It has the same construction as the Emergency Pipe Clamp except it is double in length. The ample weight of this clamp gives a generous margin of safety for high pressure work.


     With bolts along one side and a hinge along the other, it can be quickly installed under pressure without interruption of service.

The Pipeline Clamp is made of nodular iron, heavily reinforced design throughout, equipped with a crescent-shaped pressure equalizing gasket for each individual pipe size and cemented in place.

Gasket is Buna-N.

Installation Procedure Pipeline Clamp
  1. Thoroughly clean the damaged area of pipe with a wire brush. This will help insure a bubble tight gasket seal.
  2. Place the Clamp around the pipe so that the leak is fully covered by the gasket
  3. Tighten the bolts evenly to the recommended torque (see table below).
  4. Pressure test the completed installation for leaks.
  5. Check for leaks before leaving.
