  • Properties of FRP/UPVC、FRC/CPVC plpelines

    FRP/UPVC and FRP/CPVC composite poise and titttiongs are made with visin UPVCpiping material flttings or chlorinated polyvinyl chloride plping materlas fittings as the lining layer on the Insede, and fibre glass reinforced plasig as the reinforcing layer on the outside, thess materials are joined to each other with interfacial bond and then entwined together with special machines,these plpes feature the anti-erosion property of UPVC and CPVC materials, and the high strength and temperature resiscanec of FRP materials. While ellminating the flaw of UPVC and CPVC materials,namely inferlor ability to resist pressure at a high temperature and high proneness to age when put outdoors,henoe the application range of UPVC,CPVC and FPR pipe products is widened.
    FRP/UPVC and FRP/CPVC composite pipes and fitting are inexpensivek,easy to install and repair, enduring for ues, smooth on liside wall,and feature low frion, good resistance to erosion, temperature,pressure,wear,and are well designable,the interfacial bonding strength of FRP/UPVC,and FRP/CPVC products are strong so shey feature strong resistance to impact in addition,they feacture other advantages like low friction for flulds, no electric of chemical ndustry, machinery, metallurgic, light industry,electriclty etc, bringing good economic returns.
