RESERVOIR FOR STORAGE OF EASILY EVAPORATING LIQUIDS Russian patent published in 1995 - IPC

FIELD: reservoirs for storage of easily evaporating liquids. SUBSTANCE: reservoir has bottom and wall made of roll blanks. In mounting the reservoir, lapping portion of end edge of roll blank of the wall are cut forming stepped joint; after welding horizontal sections 6 and vertical sections 7 of mounting joint 5 of lower strake, end edges of upper strake are cut away; initial and final sections of end edges of roll blank 1 are secured for motion under action of forces arising due to deformation in the course of shrinkage of strakes welded beforehand, thus reducing internal stresses in reservoir and preventing its deformation. For welding the horizontal sections of the joint, use is made of templet which keeps the reservoir wall from deformation in the course of welding. EFFECT: enhanced reliability. 2 cl, 2 dwg
