Large-scale oil storage tank, with capacity of more than 100 cubic meters, is a large container for storing crude oil or other petroleum products. Large-scale oil storage tank consists of tank wall, tank top, tank bottom and tank accessories. It has the characteristics of long service life, corrosion resistance, high temperature resistance, high pressure resistance and scale prevention. It is the main equipment of oil depot. Large-scale oil storage tank is mainly used in refineries, oilfields, oil depots and other industries. The oil storage tanks mainly adopt A537CL1, Q345R, 16MnDR, Q370R, S30408, SU30408, A516 grade 70, A516 grade 60 etc. steel grades. Large-scale oil storage tanks are divided into fixed-roof tanks, floating-roof tanks and spherical tanks according to structure.
API 650, API STD 650 Welded Tanks for Oil Storage, is the most widely used standard for global tank construction and procurement. API 650 tank is commonly used for oil, gasoline, diesel, chemical and production water storage. API 650 tanks are located in refineries, docks, pipelines and production facilities throughout the United States. API 650 specifies the design, processing, welding, inspection and installation procedures for storage tanks.
API 620 Design Standard is a specification for design and construction of large, welded, low pressure storage tanks. API 620 tanks are used for products which have high internal pressure such as liquefied natural gas (LNG) and cryogenic tanks. API 620 tanks can store contents at a higher pressure (maximum 15 pounds per square inch (PSI) of gas or vapor storage) and lower temperature (-325 degrees F to 250 degrees F) than API 650.
Our main achievements in large-scale oil storage tanks in recent years are: over 160,000 cubic meters LNG low-temperature tanks - 12 sets ; over 20,000 cubic meters low-temperature tanks - more than 20 sets ; 50,000 - 150,000 cubic meters crude oil tanks - more than 100 sets ; all kinds of chemical storage tanks below 50,000 cubic meters and supporting installation projects, etc. The projects under construction are highly praised by the owners, supervisors and general contractors.
The project consists of four 160,000 cubic meters LPG tanks and supporting projects.
