Low-temperature storage tank performance:
Low-temperature tanks, also known as liquid nitrogen tanks, low-temperature storage tanks, also known as liquid argon tanks, and liquid oxygen storage tanks, are vertical or horizontal double-layer vacuum-insulated storage vessels. The inner shell is made of Austenitic stainless steel S30408; the outer shell material varies by user region, following national regulations to choose Q235-B or 345R. The inner and outer shell cavities are filled with insulating material pumice and vacuumed. The product has been inspected on-site by the National Technical Supervision Administration and issued with a pressure vessel supervision and inspection certificate. Product specifications range from 5 to 100 cubic meters, with working pressure of 0.8/1.6 Mpa. Nitrogen is a major raw material in the nitrogen fertilizer industry. In the metallurgical industry, nitrogen is primarily used as a protective gas, such as in rolling, galvanizing, plating, heat treatment, and continuous casting. Additionally, blowing nitrogen into the blast furnace can improve the quality of iron. It is widely used in the electronics industry, chemical industry, petroleum industry, and glass industry.
Liquefied Natural Gas (LNG) Storage Tank
Liquefied Natural Gas (LNG) storage tanks are specialized products for storing liquefied petroleum gas, classified as special equipment and third-category pressure vessels. They are made from 06Ni9DR material, and undergo non-destructive testing, hydrostatic and pneumatic testing, as well as on-site inspection by the Technical Supervision Bureau, resulting in a pressure vessel inspection certificate. The manufacturing process also includes external rust removal and painting. The LNG storage tanks undergo rigorous quality assessment for the material of pressure components, appearance dimensions, weld quality, operational quality, installation quality, internal equipment, and safety accessories.
Routine physical and chemical tests for the tank material, such as mechanical properties and chemical composition.
The welding joints, welds, tank heads, and the mutual geometric positions of all pressure elements are rigorously inspected through X-ray non-destructive testing and magnetic particle inspection. Tests are conducted on the product's sealing, pressure resistance, and all technical indicators that could affect the safe operation of the product.
Common structures of LNG tanks include: vertical LNG tanks, horizontal LNG tanks, vertical mother-child tanks, and atmospheric storage tanks.
Liquefied Natural Gas (LNG) Storage Tank
LNG storage tanks are specialized products for storing liquefied petroleum gas, classified as special equipment, third category pressure vessels, made of 06Ni9DR material. They undergo ultrasonic testing, hydrostatic and pneumatic tests, and on-site inspection by the Technical Supervision Bureau, upon which a pressure vessel inspection certificate is issued. The manufacturing process also includes external rust removal and painting. The storage tanks are subject to rigorous quality assessments for the material, appearance dimensions, and weld quality of the pressure components, as well as operational, installation, internal equipment, and safety accessories.
Routine physical and chemical tests for the material of the container, such as mechanical properties and chemical composition.
Rigorous X-ray non-destructive testing and magnetic particle inspection are conducted on the welding joints, welds, tank heads, and the mutual geometric positions of all pressure components. Testing and examination are performed on the product's sealability, pressure resistance, and all technical indicators that could affect the safe operation of the product.
Common structures of LNG tanks include: vertical LNG tanks, horizontal LNG tanks, vertical mother-child tanks, and atmospheric pressure tanks.
Vertical LNG Storage Tank
Volume options include 50, 100, 150, and 200 cubic units.
Horizontal LNG Storage Tank
Volume available in 50 cu and 100 cu.
Vertical mother and child drums
A mother tank is an inner tank composed of multiple sub-tanks connected in parallel to meet large capacity storage needs. Multiple sub-tanks are assembled side by side within a large outer tank. The number of sub-tanks ranges from 3 to 7, generally not exceeding 12. The volume of a single sub-tank should not be too large, usually between 100 to 150 cubic units, with the maximum reaching 250 cubic units. Common sizes include 1000 cubic units, 1750 cubic units, and 2000 cubic units.
