LNG (liquefied natural gas)

Pressure relief valves, cryogenic safety valves and deflagration / detonation flame arresters

CASH, BAILEY, BIRKETT, MARVAC and MARSTON protect LNG storage tanks from atmospheric pressures and over pressurisation. AMAL prevents the propagation of flames to protect pipelines and storage tanks from fire and explosion.

Cryogenic pressure relief

Liquefied natural gas (LNG) is typically stored at very low temperatures in insulated atmospheric pressure storage tanks and turned back to a gas on site, whenever demand is generated. The extreme temperature difference between its cryogenic storage temperature and the changing ambient temperature means that internal pressure needs to be released on a regular basis in order to protect the tank from damage.

Cryogenic relief valves, safety valves and bursting discs from CASH, BAILEY, BIRKETT and MARSTON protect LNG storage tanks from the effects of temperature changes and subsequent over pressurisation, while MARVAC low pressure relief valves and tank blanketing valves allow the tank to breathe, preventing damage and spillage. AMAL Flame arresters can be installed on the tank roof to prevent the propagation of fire into the system

BIRKETT safety relief / pressure relief valves

BIRKETT safety relief / pressure relief valves prevent damage to pipelines due to pressure build up. 

The Birkett Range includes:

BAILEY pressure reducing / regulating safety relief valves

BAILEY pressure reducing / regulating safety relief valves provide pressure regulation to protect from the effects of temperature changes.

The Bailey Range includes:

CASH cryogenic relief valves and bursting discs

CASH cryogenic relief valves and bursting discs protect the dewar from over pressurisation. These include:

MARVAC low pressure tank protection

MARVAC low pressure tank protection products prevent pressure building up and damaging pipes connected to the tanks. 

The Marvac range includes:

AMAL in line & end of line deflagration / detonation flame arresters

AMAL in line & end of line deflagration / detonation flame arresters prevent flames escaping from pipelines if material being carried is ignited. 

The Amal range includes:

MARSTON bursting / rupture discs and explosion vent panels

MARSTON bursting discs relieve dangerous build up of pressure, protecting pipework.

The Marston range includes:
