As convinient coupling way, FRP flanges are widely used in various pipeline systems. 

We have various flanegs include whole flange, lap joint flange, slip-on flange, threaded flange, blind flange, stub flange, duct flange, raised face flange, full face flange, flat face flange, vanstone (van stone, conrac) flange, ect.

Frp flange and frp pipe fitting is 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.

Our pipe fittings include 45 degree elbow, 90 degree elbow, tee, cross, flange, Y-type pipe, adapter pipe, and so on. Some pipe fittings could be processed live, such as elbow, triplet, cross, and so on, in order to easy implementation.
