37° Flare Flange
The flared configuration is based on flaring the pipe ends to 37 degrees and utilizing flanges and internal cones. O-Ring face cone with o-ring seal mating to flat face cone. Both internal cones have back-up o-rings.
Standard flare flanges and pipe are available from 1/2" - 8" and pressures to 6000 PSI. The standard connection styles offered conform to SAE and ISO 4-bolt flanges. Other flange patterns may also be available.
The flange is slipped onto the pipe before flaring. After flaring, the cone is located into the pipe. Bolting the flanges together draws the flared pipes and cones in contact with each other providing a leak-free connection.

Retain Ring Flange
The retain ring configuration uses heavy wall pipe and has a machined butt end face, along with an annular groove on the outside diameter. After machining, the flange is slipped onto the pipe and a retain ring (which consists of a segmented stainless steel ring bound by a spiral wound stainless steel spring) is sprung over the pipe’s outside diameter nesting in the annular groove.
Bolting the flanges together draws them against the retain rings with the o-ring seal retainer captive within the connection. Pipe sizes 1 1/2" through 10" are available for use with retain ring flanges. The standard connection styles offered conform to SAE and ISO 4-bolt flanges along with Tube-Mac® Industries 8-bolt proprietary flanges. Other flange patterns may also be available.
