CBC Breaking Bolt Type 'Industrial Version'

Installation between a hose assembly or loading arm and a fixed point, e.g. pipe system, rail tanker or road tanker connection.
Release by pull at any angle up to 90 degrees.

Cryogenic Breakaway Coupling with integrated shut-off valves. Used to protect hose assemblies and loading arms against excessive loads, e.g. due to drive / pull away incidents or rapid removal of the mobile tanker in emergency situations.
Designed with breaking bolts; activation at a defined tensile (pulling) force on the transfer line being applied at an angle of up to 90 degrees.
Suitable for the transfer of cryogenic liquefied gases (LNG, nitrogen, oxygen, argon, ethylene etc.). down to -196° C.
Typical applications include container discharge, fuel bunkering truck-to-ship, ship-to-ship, terminal-to-ship, loading / unloading of tank trucks, rail tankers and ships.

CBC Breaking Bolt Type 'Marine Version'

Typically installed between two hose assemblies.
Release by axial pull only.

Cryogenic Breakaway Coupling with integrated shut-off valves. Used to protect hose assemblies against excessive loads, e.g. due to pull away incidents or rapid removal of the vessel in emergency situations.

Designed with breaking bolts; activation at a defined tensile (pulling) force on the transfer line being applied applied axially.
In comparison to the 'Industrial Version' the coupling offers an increased resistance to torsion and bending loads to prevent unwanted separation.

Suitable for the transfer of cryogenic liquefied gases down to -196° C.
Typical applications include container discharge, fuel bunkering truck-to-ship, ship-to-ship, terminal-to-ship.

CBC-C Cable Release Type (with collar)

Installation between loading arms or hose assembly and a fixed point, e.g. pipe system, rail tanker or road tanker connection.
Release by pull at any angle up to 90 degrees.
These couplings are used when very low separation forces are required.

Cryogenic Breakaway Coupling with integrated shut-off valves. Used to protect hose assemblies against excessive loads. Special type, recommended in transfer systems with the combination of high operating pressure and weak piping structure.
Compared with Cryogenic Break Couplings with breaking bolts, CBC-C are designed with a clamp system and an external collar with an attached cable.
The tensile force (pulling force) is not transmitted via the hose or loading arm, but by an integrated cable which is attached to a fixed point.
Release forces are almost independent from the internal pressure (operating pressure).

After the admitted travel limit of the cable is reached (angle up to 90 degrees), only a small pull is sufficient to actuate the separation.
Suitable for the transfer of cryogenic liquefied gases down to -196° C.

CBC-PERC

Powered Emergency Release Coupling with remote controlled release, additionally passive release as safety backup.

Installation between hose assembly or loading arms and a fixed point, e.g. pipe system, rail tanker or road tanker connection.
Release remote controlled, or by pull at any angle up to 90 degrees.

Cryogenic Breakaway Coupling with integrated shut-off valves. Special type, used to protect hose assemblies and loading arms against excessive loads and for manual release in emergency situations.

Two activation methods:
1) Pneumatic, remote-controlled release - MannTek supplies this coupling as a system including control and monitoring system
2) At a defined tensile (pulling) force on the transfer line being applied at an angle of up to 90 degrees.
Suitable for the transfer of cryogenic liquefied gases (LNG, nitrogen, oxygen, argon, ethylene etc.). down to -196° C.
Typical applications include container discharge, fuel bunkering truck-to-ship, ship-to-ship, terminal-to-ship, loading/unloading of ships.
