Used to ‘prove’ the internal bore of a pipe or duct prior to the installation of a liner or cable. This is our Solid Nylon Proving Pig version. Also see our Steel Dumbbell Style version. We can supply any size of Proving pig. However, the diameter is normally 10% less than the ID of the pipe.
Solid Proving Pig
The Pipe Equipment Specialists Solid Proving Pig is used to prove that the internal dimensions of a pipe or duct, do not fall below a minimum diameter, and that the pipe/duct has a circular profile. The Solid Proving Pig is simply pulled through the pipe/duct.
The Solid Proving Pig is supplied with a towing eye at both ends so that a rope may be pulled in at the same time to allow the pig to be retracted, if necessary, or to act as a cable draw cord.
