Complete list of low-temperature storage tank manufacturing, high-quality products for low-temperature oxygen nitrogen argon storage tanks

Description :

　　Shandong Zhongjie Special Equipment Co., Ltd.'s main low-temperature storage tank series products are mainly used for low-temperature liquid storage of gases such as liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, and carbon dioxide. 1 cubic meter of liquid can replace 130 steel cylinders. It can replace daily transportation with gas cylinders, saving a lot of manpower and material resources.

　　The low-temperature storage tank series products are double-layer vacuum powder insulated storage tanks used for storing liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide, and liquefied natural gas. Beautiful style, compact pipeline valve structure, centralized control, small footprint, easy operation. It has the characteristics of long service life. This product is widely used in gas industry, hospitals, metal smelting and other users with high gas consumption, and is an excellent product for achieving centralized gas supply.

　　Main technical parameters (vertical, horizontal) Product models: 5 cubic meters, 10 cubic meters, 15 cubic meters, 20 cubic meters, 30 cubic meters, 50 cubic meters, 100 cubic meters, working pressure 0.8MPa, 1.6MPa, working pressure of carbon dioxide storage tank 2.2MPa

　　The low-temperature storage tank is a double-layer fixed vacuum powder insulated storage tank (storage tank). The inner liner material is made of stainless steel (with 16MnDR for carbon dioxide storage tanks), and the outer liner material is Q235B or 16MnR. The surface anti-corrosion coating adopts processes such as sandblasting rust removal, blowing, and spraying, and also uses two-component rapid curing liquid coating.

　　This product is a horizontal fixed vacuum powder insulated low-temperature storage tank, mainly composed of the following four parts

　　form.

　　(1) Tank body

　　The tank body consists of an inner container, an outer shell, and an insulation layer. The tank body is a double-layer cylindrical structure, and the inner container and its piping are made of austenitic stainless steel material

　　The shell is made of Q245R material, and the interlayer formed by the outer shell and inner container is filled with pearl sand and vacuumed.

　　(2) Operating System

　　The operating system is located on the side of the tank head. The operating system is equipped with pressure gauges, differential pressure (liquid level) gauges, and various valves for observing the pressure and liquid level inside the tank

　　Operation functions such as liquid supply.

　　(3) Turbocharger and pressure regulating device

　　The pressurization and pressure regulation of the storage tank are uniformly guaranteed by the external system, and the user is responsible for it.

　　(4) Safety device

　　Both the inner container and outer shell of the storage tank are equipped with safety relief devices, and the inner container has a safety valve; The shell has a release device. (Emergency shut-off valve for equipment, to be operated by the user)

　　Reason is an inseparable part of this system.

　　2. Structural characteristics

　　(1) Compact structure and small footprint.

　　(2) The insulation material (pearlite sand) of the storage tank has been strictly treated to give the tank a longer vacuum life. At the same time, the storage tank is equipped with vacuum gauges, which require

　　When needed, connect the thermocouple vacuum gauge to measure the vacuum degree of the interlayer.

　　Safety operating procedures for liquid argon storage tanks:

　　1. Before putting the working liquid argon storage tank into use, it should undergo an air tightness test, blow off treatment, and inspection of valves and instruments.

　　1.1 After the installation of the airtightness test liquid argon storage tank is completed or the inner cylinder is restored to room temperature, a system airtightness test should be conducted before filling with low-temperature liquid. The test pressure is the working pressure of the storage tank, and the test gas is oil-free dry air or dry nitrogen. The test time depends on the size of the storage tank, but should not be less than 4 hours.

　　1.2 After passing the airtightness test, the liquid argon storage tank inner cylinder system needs to be blown off with oil-free dry air or dry nitrogen to remove humid air. After the system is blown away with dry air or dry nitrogen, it should also be blown away with product gas. During the blowing process, lighter gases than air are added from the top of the storage tank through a vent valve, and the bottom is discharged through a liquid inlet and outlet valve. In order to accelerate the removal of moisture from the tank, the blown gas can be heated to 80-1000C. Each pipe valve should be blown separately, especially the liquid level gauge and pressure gauge. Gas should be removed from the joint to remove moisture from the pipeline until the dew point of the exhaust gas from the inner cylinder system meets the requirements before filling can begin.

　　1.3 Inspection of Valves and Instruments Before filling with low-temperature liquid, it is necessary to carefully check whether the valves are in the correct position, whether the instruments are flexible and reliable, and whether the connections of the level gauges are unobstructed.
