Elasto polymer processors [gujarat] supplies grp pipes by filament wound method. Filament winding method is pipe fabrication method which utilises continuous glass strand rovings. Some of the hardware features of these grp filament wound pipes include: these glass rovings are pre-saturated in a resin bath and helically wound around a rotating mandrel at a specified winding angle, which is largely 55ºc. The winding process is bidirectional layers until the desired wall thickness is achieved. This winding angle of 55ºc provide optimum 2:1, hoop to axial ratio. The grp pipes are lightweight, corrosion resistant having longer service life, excellent hydraulic efficiency, high resistance to surge pressure, non-toxic with low thermal and electrical conductivity. They are tested with tests, like longitudinal strength test, hop tensile strength test, stiffness test, beam strength test, hydro test, pipe soundness test, etc. Various accessories also are provided with these pipes like: flanges, collars, bends of 45 and 90-degrees, reducers, t-pieces, pipe spools, etc, are also available. The grp filament wound pipes are best suited for potable water and raw water, effluent and sewage water supply, chemical and fertiliser plants, desalination plants, refinery, petrochemical and petroleum plants, power plants, paper, pulp and pringing plants, pharmaceutical and formulation plants, dyes and intermediates, textile, synthetic fibre plants, pickling, metal finishing and metallurgy, food stuffs industries, biotech and biological parks, offshore oil production, etc.
