PLIDCO® Smith + Clamp

Locates and stops pit-hole leaks

So simple and sensible is the PLIDCO® Smith+Clamp design that it can be installed by a blindfolded person…certainly in darkness or on a pipeline submersed in water or oil.

The pilot pin guides the cone point into the pit-hole. Pressure is then applied behind cone by a forcePlidco Smith+Clamp Product Line screw – not by drawing bolts on opposite side of the pipe. The drawbolt at the bottom of the fitting only holds the clamp in place. Exerting pressure directly on the cone eliminates the danger of caving in badly corroded pipe. Line pressure need not be reduced during installation. Available in sizes 1-1/2” through 48”. Special sizes on application.

Requires much lower bolting pressure
Since the point of the PLIDCO® Smith+Clamp cone is centred exactly on the leak, a minimum of force is required to shut-off the leak. For example, a 1/8” diameter hole is 0.012 square inches in area. At a pipeline pressure of 1000 psig only 12 pounds of force is needed to push the cone into the leak.
