Welded steel tank apparatuses

The cylindrical steel cylindrical vessels with the volume from 0,001 m3 to 500 m3 work under pressure not more than 50,0 MPa, vacuum with residual pressure not lower than 0,013 Pa or without pressure (under filling). Service life of the apparatuses is not more than 30 years. The apparatuses are designed for reception, storage, heating of liquid and gaseous means with temperature from minus 70 C to 700 C. By purpose and design apparatuses are subdivided into the following types of equipment: drainage equipment; cylindrical capacitive apparatuses for gas and liquid hydrocarbon media; cylindrical horizontal vessels for liquefied hydrocarbon gases propane and butane (above-ground and underground); steel capacitive apparatuses; horizontal steel tanks for light and dark petroleum products (above-ground and underground); collectors; vertical apparatuses with stirring devices; capacitive gummed equipment; air collectors.
