After machining, the flange is slipped onto the pipe before flaring. After flaring, the cones are located into the pipe. The O-Ring face cone with the O-Ring seal mates with the flat face cone. Both the cones have back-up O-Rings. Bolting the connection together draws the flared pipe and cone in contact with each other providing an elastomer seal at the flare and at the face.
The flanges can be rotated prior to bolting thus eliminating the need to be concerned about the axis of the pipe on which the fitter aligns the flange holes. At times, it also allows the flange cap screws to be installed in more confined spaces. Learn more on how pipe is grooved.
Retain Ring Flange system is used for pipe sizes ranging from 1-1/2” through 10” are available for use with pressures up to 6000 psi. The standard connection styles offered conform to SAE Cd 61 (ISO 6162 -1), SAE Cd 62 (ISO 6162-2), ISO 6164 4-bolt flanges along with TMI® 8-bolt, 9-bolt proprietary flanges. Other flange patterns may also be available. TMI has in-house developed portable Grooving machine
to meet the required standard of grooving needed for retain ring flange system. Grooving machine operator needs basic training to operate the equipment which will be provided by our installation team. Learn more about the grooving machine.
Retain Ring Flange System is extensively used in Hydraulic Applications in Automotive, Locomotive, Aerospace and Seismic Testing.
Select the required bolting hardware from Section R of this catalogue
. Carefully place the ‘o’ ring seal retainer in between the pipe ends. Slide the flanges forward and the ‘o’ ring seal retainer becomes captive within the flanges.
