FIELD: storage and delivery of liquefied hydrocarbon gases. SUBSTANCE: tanks includes vessel coming in the form of cylindrical shell and two convex bottoms welded to it, pipe-line with flange to feed and extract liquefied hydrocarbon gases. Vessel is fitted with boss installed on bottom in zone of 10% filling of tank, in point of minimal stresses of isofield of computed equivalent stresses of bottom. Pipe-line to extract liquefied hydrocarbon gases is located outside of vessel, is double wall structure with additional flange put on another end of pipe-line. One of flanges is joined to boss. EFFECT: prolonged service life and increased safety of maintenance of tank. 2 cl, 3 dwg |
