Caustic-Service Flanges
Nickel Flanges
Nickel 200 & 201 flanges for caustic soda, food-processing and electronics-industry piping connections.

ASTM / ASME Certified Material
Product Overview
Nickel flanges complete the piping circuit on caustic and high-purity process lines where pure nickel pipe is specified — matched grade-for-grade to avoid galvanic or contamination issues at the joint.
Weld neck and slip-on types are held in both Nickel 200 and 201, machined to ASME B16.5.
