Low temperature operation of pressure vessel with decreasing temperature, the container used steel and its weld will change from ductile brittle state, the compression element in tensile stress under the action of stress levels below the yield strength of the material, or less than the allowable stress under the condition of sudden brittle fracture. After this break, no or only minimal local plastic deformation, but no overall yield, imperceptible in daily life, but often a catastrophic accident, and even pose a great threat to the safety in production. Therefore, compared with the non cryogenic pressure vessel, the design, manufacture and inspection of low temperature pressure vessel are more strict.

With the increase of the scale of petrochemical plant, the volume of the container increases, the pressure vessel is more and more in the field assembly welding, and the blocking of the large diameter nozzle on the container is the difficult point of pressure test.

Test scope: import and export pressure vessel inspection includes the following: pressure vessel design review, operation of pressure vessel quality inspection, pressure vessel installation quality inspection, pressure vessel repair quality inspection, operation of pressure vessel quality inspection. In short, all can affect the safety operation of the pressure vessel project, are the scope of the test.

2003 Guangzhou Huakai liquefied petroleum gas Co., Ltd design and manufacture of 10000m3 butane spheres is the largest domestic spherical tank is designed and made by our company, the manufacturing level identified by the Liaoning provincial economic and Trade Commission "is to design and manufacture of spherical tank in China's largest store of butane, for domestic initiative to fill," China cannot manufacture large spherical tank blank, make a great contribution to national saving foreign exchange.
