T.D.Williamson - Pigging Products
TDW's BiDirectionAll Pig is designed to be used in pipeline construction during the hydrostatic test phase for air or water displacement applications. This pig is bidirectional, which allows the pig to run in either direction. It is designed to allow the user to fill the line with hydrotest water and then displace the water without having to remove the pig. It can be used as a bidirectional cleaning pig by adding optional brushes.
