    FRP Pipings


    Zhongyi FRP Co., Ltd manufactures filament wound pipe, pipe fittings and flanges of different diameter in accordance with standards published by ASTM, ANSI, AWWA, ASME . Pipe, pipe fittings and flanges are manufactured from corrosion resistant epoxy vinyl ester, polyester, isophthalic resins.
    Pipes & ducts
    Pipes & ducts are manufactured using the "Dual helix" filament winding process on computer controlled machines. By adjusting the relative speed of mandrel rotation and glass distribution head movement, helical reinforced layers with different angles can be wound. In order to increase the pipe stiffness, especially on large diameter pipes, silica sand can be added to parallel layers of wall.
    Nominal diameter
    Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 20 to 4000 mm.
    Nominal pressure classes:
    Pipes and fittings are classified according to nominal pressure. Standard pressure classes are 4, 6, 10, 16, 20 and 25 bars. Intermediate or higher-pressure classes are considered on request or depending on the design parameters and conditions
    Nominal lengths
    Pipes have a length of six meters up to ND150 and 12 meters for bigger diameters.
    Fittings
    A wide range of fittings as elbows, reducers, tees, caps, flanges etc. is available.
    Fittings are manufactured by the hand lay-up, contact molding and spray-up process. In hand lay-up and contact molding processes veil and alternate layers of mat and woven roving saturated with resin are applied on the mold. In spray-up process continuous strand roving is fed through a chopper gun, combined with catalyzed resin, and sprayed onto the mould surface
    Prefabrication spools
    Prefabricated spools save installation time as well as costs, freeing the designer from being limited to standard fittings and allowing junction sizes shapes to be specified and manufactured as a better alternative to a complex series of joints.
