what's Large-scale oil storage tank

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.

Standards of oil storage tank

API 650

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

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.
