Emergency Release (ERC) Breakaway Couplings

Collar Release (ERC) Couplings are typically used between a breakaway coupling on a pipe or on a loading arm, the cable minimizes the tensile strengths being exerted. The collar is released by a pneumatic, hydraulic, mechanical or a combination of hydraulic / mechanical system. The collar is released / activated at a predetermined point either by an overextension of the hose or loading arm.

Materials of Construction: Carbon Steel, Stainless Steel, other metals

Seals: Rubber seals, or PTFE

End Connections: Typically flanged ends.

Sizes: 1" to 12"

Emergency Release Collar - Dual / Hydraulic & Mechanical Operation

The Dual Emergency Release Coupling is designed to work as Follows: This is a typical application: When an operator is present at the site and the operator sees a ship drifting away and a stress on the system is about to occur, the operator can intervene directly by pumping the hand pump, which is located at some distance from the coupling, and with 2 or 3 strokes create enough pressure thus moving the hydraulic cylinder on the coupling. The cylinder moves applying pressure on the collar release mechanism thus causing a release and the poppets close. The half of the coupling that falls off is kept from falling into the water by a cable that is attached to the other half of the coupling. If the operator is not present at the site to intervene in case of a ship drifting away, then the mechanical back up cable release takes over.
