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.
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.
