Fiberglass Pipe Flanges for Corrosive Chemicals
- For Use With: Acetic Acid (75%), Alcohol, Calcium Chloride, Chlorine, Fuel Oil, Gasoline, Hydrochloric Acid (37%), Nitric Acid (10%), Oil, Phosphoric Acid, Salt Water (30%), Sodium Hydroxide (50%), Solvents, Sulfuric Acid (70%), Water
- Temperature Range: 32° to 200° F
- Specifications Met: ASTM D4024
Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.
To connect flanges to pipe, first sand the inside of the flange and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8” thick. Repeat this process with the inside of the flange, applying a layer approximately 1/16” thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.
Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

Fiberglass Flange Nuts
These fiberglass flange nuts are chemical resistant, nonconductive, and lightweight. They have a flange that distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Height includes the flange.

High-Temperature Breathable Round Bellows with Flange Ends
These fiberglass bellows withstand temperatures up to 450° F—about twice as much as standard breathable round bellows with flange ends. They also protect against flames and sparks. Slide these bellows over moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.
