ISO Flange Assembly Instructions

Opyopnal fastener flanges are joined around the periphery with calmps

Double claw clamps are used when a pair of OF flanges are joined. or single claw clamps are used to join an OF flange to a tapped nonrotatable on a pump or gate valves. 

This fasten method allows the OF flange to b erotateforease of component alignment. Additionally, a rotatable bolt ring can be used to a fasten an OF flange to a nonrotatable flange using bolts. 

A retainer ring prevents the OF flange from slipping through the bolt ring. Nonrotatable ISO flanges are assembled with bolts.

They do not allow rotation of bolt holes on mating flanges to align components.
