Pipe Flanges for Chemicals

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Class 150 flanges.

Fiberglass Pipe Flanges
for Corrosive Chemicals

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 to create an access point within a line.
