NDT of Weld Seams of Inner Shells of Liquid Ammonia Isothermal Storage Tanks: Carrying out and Results

N. N. Gubarev, G. D. Stenin

Specialists of OAO “AZOT” (Kemerovo) during regular full technical inspection of liquid ammonia isothermal storage tank of 10,000-tone capacity fulfilled by ZAO “GIAP-DISTcenter” (Moscow), have been carried out non-destructive testing of its constructional elements. Basing on the results, some areas of inner shell weld seams were repaired and a section of bottom sheet was replaced. One of the possible variants of a «new» diagnostic scheme is offered for amendment of the current instruction on complex technical inspection of liquefied gas isothermal storage tanks.
