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.
Modern Group offers dual services in the field
of testing of cylinders in accordance to the gas cylinder rules
2004 led down by department of explosives. |
