Tightness Testing Of Gas Tanks

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:

• Smell of gas starts coming in the environment.
• The pipe work is changed, it is either painted or new joints are included. Even when new covers are added it is equally important to check for tightness because screws and nails can create holes unexpectedly.
• After alterations have been done to the pipes or assigning them to new routes.
• Prior to starting the rework on the pipes or the tanks.
• After the fitting work has been completed.
• If the space or facility is rented, the owner would demand a yearly inspection to know that his place is safe from any future accidents or fires.
• After refilling the gas because too much pressure can put a great load on the joints and weaken or loosen them.

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.
