IGF’s Premium Quality FRP Flanges
 

Monolithic All Hand Lay-up Construction

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

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

Not Machined: The nozzle necks and backs of IGF flanges are not machined. DuPont SW 12 S 6.7.1.1. says, “Overall machine facing of the back of the hand lay-up flange is not permitted.”

Resin: Flanges are stocked in Ashland Hetron 922, both MEKP and BPO DMA cure. We also have a large inventory of Derakane D470 and ISO flanges. Other resins are available upon request. 110 mil Corrosion Liner: C-Veil+Nexus+2 Mat. D470 and BPO flanges are all double nexus construction

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

Abrasion Resistant Flanges: IGF can produce flanges to meet your specific requirements. We have extensive experience in producing abrasion resistant flanges to handle the abrasion problems encountered in the Coal Fired Electric Generation Industry. Fly Ash, Bottom Ash and other abrasive slurries can now be handled through the introduction of fine particles of Silicon Carbide into our standard corrosion barrier.

All IGF flanges are of Type II construction, Mat plus alternating layers if 1 1/2 oz Mat and 24 oz Woven per ASME RTP-1 table 2A2. This makes our flanges 1.7 times stronger in the critical flange and hub area than a typical Type I (all Mat) flange.
