Mann Tek - Dry Cryogenic Coupling

dry cryogenic coupling 4inches

Dry Cryogenic Couplings (DCCouplings) and Cryogenic Break-away Couplings (CBCouplings) are designed for use wherever it’s beneficial to connect and disconnect hoses and pipelines under pressure, quickly without spillage and additional tools.

Dry Cryogenic Couplings and Cryogenic Break-away Couplings are designed primarily for the use of cryogenic liquefied gases, e.g. LNG (-163ºC) and e.g. Nitrogen (-196º), where safety and reliability are of highest concern.

 

The Dry Cryogenic Coupling consist of a “tank” unit wich is a type of a non-return valve and a “hose” unit with a valve driven by an internal cam curve to open both valves at the same time. Operation is a single action using a straight forward turning motion to connect the couplings and open flow path. An initial push and turn action on the hose unit provides engagement with the tank unit, thus locking and sealing the two units together. Further rotation opening the internal valves, thereby allowing full flow with a minimum of pressure drop.

 

DCC couplings are available from van 1" to 6" in stainless steel with threaded or flange connections. Working pressure 25 bar (6" 16 bar).

 


Cryogenic Break-away Couplings are a further development of the Safety Break-away Couplings which has successfully been used to prevent pull-away accidents in the petroleum, chemical and LPG industry all over the world. The new range of Cryogenic Break-away Couplings can be installed either at fixed points or in the middle of hose strings.
cryogenic breakaway couplings

Industrial cryogene break away, Typically installed into loading arm and hose assemblies, where at least one side of the coupling is attached to a fixed rigid point.

Marine cryogene break away, Marine Cryogenic Break-away Couplings are designed to only release by inline pull and used between two strings of hose.

 

CBA couplings are available from van 1" to 6" in stainless steel with threaded or flange connections. Working pressure 25 bar (6" 16 bar).
