Cryeng Group is an experienced manufacturer of cryogenic tanks (cryotanks), cryogenic vessels, cryogenic surge drums, and cryogenic pressure bullets.
Founded in 1965, Cryeng has since designed and fabricated more than 2,000 cryogenic tanks, vessels, surge drums, and pressure bullets, for clients worldwide. We have registered designs for static and dynamic applications, vertical and horizontal configurations, and a range of liquefied mediums included LNG.
The inner vessels of Cryeng’s cryogenic tanks are typically constructed of stainless steel, or low temperature carbon steel for foam insulated vessels. The outer vessels of the cryogenic tanks are fabricated from carbon steel or stainless steel, to provide vacuum insulation for the inner vessel.
Cryeng’s vacuum insulated cryogenic tanks can be designed and manufactured to AS 1210, ASME VIII Pressure Vessel code, and any other applicable Australian & International Standards. Advanced design technologies allow accurate analysis of foreseeable operating conditions, including seismic and cyclonic wind conditions to AS 1170, transportation induced loading, normal & abnormal operating pressures, and the elements.
The cryogenic tanks (cryogenic vessels, cryogenic surge drums, cryogenic pressure bullets) are manufactured to ISO9001 quality control procedures, with the following testing done on all cryogenic tanks fabricated by Cryeng Group:
- Full hydrostatic testing for Class 1, 1H, 1S, ASME VIII Div. 1 and Div. 2 inner vessels
- Helium leak testing to verify vacuum integrity of inner vessel jacket
- Soapy bubble testing of all cryogenic valves and external piping
- Cold shock testing of inner vessels with liquid nitrogen for nozzle and pipe integrity check
