Gases like oxygen and nitrogen are filled in seamless steel cylinders at high pressure ranging from 150 to 200 bar. Such cylinders are also subjected to various weather conditions and handling during use at consumer's place as well as transport, loading and unloading. Essentially, the cylinders are made of a material that has a flexibility of expansion and contraction during pressurization.
For various reasons this flexibility of expansion and contraction begins to deteriorate over a period of time. Similarly, on account of other conditions such as filling, handling, transportation and shop floor conditions, there are chances of weight reduction over a period of times. It may also develop certain other defects normally rendering a cylinder unsafe for use.
lobally such cylinders are required to be periodically tested for visual damages, weight loss and loss of elasticity. In view of the dimension of damages, which can be caused by a dilapidate cylinder, being known, most of the gas industries and users world wide are required to test cylinders periodically.
Universal Welding & Engg Co. offers dual services in the field of testing of cylinders in accordance to the gas cylinder rules 2004 led down by department of explosives.
