Eissa Fiber Glass procedure used to manufacture GRP pipes involves a continuous filament winding machine that employs the continuously advancing mandrel process. The winder is made up of a steel band that is supported by beams to form a cylindrical mandrel. The beams rotate, causing the band to move around it. A roller bearing allows the band to move longitudinally, causing the mandrel to move in a spiral path towards the end of the machine. During this process, glass fibers, resin, fine graded filler, and surface materials are added in precise amounts, which are controlled by a programmable logic controller and computer. The process is controlled by a preprogrammed process, which provides integrated process control. The thickness of the laminate is measured by another device that rotates the pipe at the cut. The thickness measurements are recorded and displayed on the operator’s computer monitor.  In addition, a release film, surface mat, and other surface liner materials are applied from rolls adjacent to the mandrel. The laminate is heated by steel band and infrared elements, while the saw and calibration unit are in sync with the continuous longitudinal movement of the laminate, resulting in a clean perpendicular cut of the pipe. The pipes can be cut to any length as pre-set. Once cut, the pipe is supported on specially designed lifting tables and moved by conveyor to the hydrostatic pipe tester.
