Abstract

The decisive factor in the process of technical verification of cylinders is conditioned by correct choice of the inspection method, in order to attentively catch possible imperfections caused by the wear and tear resulting from long term use. Emphasis is placed on safety conditions of cylinders, which include mandatory minimum technical requirements for periodic inspection of liquefied or compressed gas cylinders. Cylinders are an assembly consisting of: under pressure receptacles with a volume of 0,5 to 150 litres, serving for transport and storage of liquefied or compressed gas; the associated casing, which may be: a filling and drainage device, a security device, a pressure relief device, a measuring device, a valve coupling element, a fastening element fitted on the container, a setting and protection element and a protection to heat device. The current paper presents the optimal method of inspection and verification of cylinders for compressed, liquefied or dissolved under pressure gases, represented by the use of the hydraulic sample stand in accordance with international principles and practices.
