GRP Pipe Technology

GRP Pipe Technology is using the continuous advancing mandrel process which represents the state of the art in GRP pipe production. Using technology developed by material specialists, a very compressed laminate is created that maximizes the contribution from the three basic raw materials glass-fiber, resin and sand. A sand fortifier is used to provide increased stiffness by adding extra thickness, placed near the neutral axis in the core. With a dual resin delivery system, the equipment has the capability of applying a special inner resin liner for severely corrosive applications while utilising a standard type resin for the structural and outer portion of the laminate. Taking advantage of the winding process, other materials such as a glass veil or a polyester veil can be used to enhance the abrasion, the chemical resistance and the finishing of the pipe.
