The use of gases is increasing in the factories around the world. As these gases are used for many different reasons such as nitrogen is used for cooling purposes and compressed gas is used in hydraulics known as pneumatics. Carbon dioxide is used for manufacturing fertilizers and even in soda pops. The increasing use of gases has forced the factories to even change their structures and many amendments and new installations have taken place lately to enhance safety and productivity. After some time it becomes necessary to check for tightness of the pipes and the tank by the popularly known method as hatch cover ultrasonic tightness testing for the various reasons as below:

Why gases are used in factories
The exact incident why gases started being used in factories is unknown. It is believed that the use of gases in factories began after it became clear that steam can be used to pushed heavy loads and the first locomotors came into existence. The use of steam made its way into the factories to be used in various ways and today also steam is being used in the fertilizers industry, textile industry, packaging industry and hundreds of other applications.

The commonest gas being used worldwide is the LPG which is used in homes and factories for combustion purposes. However, the gases need to be refilled sooner or later and the refilling process often turns the containers weak. It becomes necessary to for checking the health of the containers by the method known as checking tightness of hatch with ultrasound. Upon checking the tightness it becomes clear if there is anything demanding replacement or retightening. Loose joints can be vulnerable and can put the entire building at risk.
