FRP Pipe

<Characteristic>
·Design and Manufacture with liquid and pressure to use.
·Replace an iron and PVC PIPE because of chemical resistance and heat resistance.
·Use semi-permanently.
·No restriction on where it is installed, because of the easy modification to the existing size and angle of fittings.
