Horizontal cylindrical vessels for liquefied hydrocarbon gases of propane and butane

TU 3615-044-00220302-02 (OKP 36 1510) Cylindrical horizontal vessels are intended for land storage of liquefied hydrocarbon gases of propane and butane at wall temperatures from minus 60 ° C to + 50 ° C, installed at oil refineries, petrochemical, chemical, gas and other related industries, as well as gas-filling bases and stations . It is allowed to use vessels for the storage of other liquefied hydrocarbon gases, the vapor pressure of which at a temperature of + 50 ° C does not exceed the vapor pressure of propane and butane, respectively. Butane vessels should be used to store light gasoline fractions. Vessels can be operated in the conditions of macroclimatic areas of a temperate, cold, tropical climate. Climatic modification "UHL" and "T", product category I according to GOST 15150-69.
