Cryogenic Vessels are designed for storage
and transport of liquid gases at sub - zero temperatures. Manufacturing
of such vessels requires special technical know how and sophisticated
fabrication techniques.
Cryogenic tanks are used to supply
liquefied oxygen, nitrogen, argon and other liquefied gases. The
tanks have the advantage of low area requirement, safety, simple
operating convenience and are widely used in the field of gas ,
chemical , machinery medical treatment, electronic, mining and
metallurgy.
The tanks can supply cryogenic liquid from
the bottom by connecting it to an outer vaporizer and cryogenic
pump. We can supply the whole system along with the valve system
and piping based on the customer requirement.
Cryogenic Vessel is essentially a double
walled cylindrical tank, annular space between inner and outer vessel
is filled with and insulating material and evacuated to a high vacuum
to achieve minimum evaporation losses. The cold converter is fitted
with pressure building arrangement with automatic pressure build - up
regulator.
Design of vessels is compact sturdy and easy to operate. Top and
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
It has better advantages like are
- Simple tube structure.
- No need to replace the insulation material regularly.
- Excellent insulation and low static evaporation.
- Tank interlayer passes strict leakage test by helium gas spectrometer with a leak rate of less than 1 x 10 ?¹º pa-l/s.
- Convenient system operation and small area requirement.
