Frp flange 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.

3 Usage:connecting pipe line and keep its leakproofness,convenient for replacing pipe line .Easy to separate and check the situation of pipe line .easy to seal pipe line .

4 Dimensions: flange, hub, and neck thicknesses meet or exceed ASME Sec. X, ASME RTP-1, ASTM D3299, and PS 15-69.

5 Pressure Rating: Flanges are stocked in 50psi, 100psi, and 150psi. All bolt holes and bolt circles are per ANSI B16.5 150 lb. drilling.

6 Resin Coating: All bolt holes and spot facing are resin coated.
