Flowtite pipes are manufactured using the continuous advancing mandrel process which represents the state of the art in GRP pipe production.
This process allows the use of continuous glass fibre reinforcements in the circumferential direction. Using this technology developed by material specialists, a very compressed laminate is created that maximizes the contribution from the three basic raw materials. Both continuous glass fibre rovings and choppable roving are incorporated for high hoop strength and axial reinforcement. A sand fortifier is used to provide increased stiffness by adding extra thickness, placed near the neutral axis in the core. With the Flowtite 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. To assure a consistently high level of product quality, it is essential that the method of fabrication be accurately controlled.
