Cryogenic Vessels are designed for storage and transport of liquid gases at sub-zero temperatures. Manufacturing of such cryogenic tanks requires special technical know how and sophisticated fabrication techniques. Universal has developed the necessary technology and has been manufacturing these cryogenic equipment like cryogenic vessels since last seven years.

STRUCTURE :-
Cryogenic Vessel is essentially a double walled cylindrical tank. Annular space between inner and outer vessel is filled with an insulating material and evacuated to a high vacuum to achieve minimum evaporation losses.

OPERATION :-
Design of cryogenic equipment like vessels is compact, sturdy and easy to operate. Top end liquid filling reduces the pressure inside the tank and pressure increases in bottom filling. Pressurizing system enables operator to increase the pressure during liquid unloading to tanks or gas line vaporizers. By regulating the opening of both top and bottom filling valves, there is no significant change of pressure during liquid delivery. This results in constant liquid supply to vaporizer.

LIQUID GAS :-
Vacuum insulated storage & transport tanks. Automatic cold convertors.

CAPABILITY :-
Storage of temperatures upto (-196°C). ranging from 1000 Ltrs. to 20000 Ltrs. with combination of low and high pressure. Cold convertors are used to allow the supply pressure pipe line networks after gasification in atmospheric heat exchangers. Cryogenic storage vessels supply networks or tanks of smaller capacity for low liquid temperatures.

MAIN FEATURES:-

Minimum evaporation loss due to high degree evacuation and filling interspace with Expanded Powder Insulant. Simple installation, cost effective & easy maintenance Sturdy construction, compact inner vessel of stainless-steel & outer vessel of carbon steel. Fitted with liquid level indicator, safety valves, pressure gauge, vacuum sensor, pressure build up valves & other fittings. Instruments suitably positioned for easy access and operation Suitable for transferring liquid gas as well as vapor gas at preset operating pressures to distribution pipe lines. Thermosiphon system for cryogenic storage vessels are meant for cylinder filling purposes to curb losses. All valves and safeties are in accordance with standard codes and approval is granted from CCE. Entire vessel is epoxy painted-white.
