DESC:This complete specification seeks priority from provisional application number 202221044271 filed on 2nd day of August, 2022 with title “PRESSURE TESTING TOOL FOR MISSILE LAUNCHING PNEUMATIC RAM OF SUBMARINE”

FIELD OF DISCLOSURE
[1] The present disclosure generally relates to the field of pressure testing and, more specifically, to a tool and method for pressure testing high-pressure components, particularly pneumatic rams, used in submarines.

BACKGROUND OF THE DISCLOSURE

[2] A pneumatic ram is a critical component installed on the internal doors of weapon launching tubes in submarines, primarily used for deploying missiles. These submarines operate under high pressure, which makes it essential to regularly check the structural integrity of their weapon launching tubes. The pneumatic ram plays a crucial role in ensuring the safe and reliable deployment of missiles in a submarine's operational environment.
[3] Pressure testing procedures are of utmost importance in various industrial applications, including the manufacturing of pipes, tanks, pressure vessels, and fittings. These tests are conducted to ensure the integrity, dependability, and leak-tightness of pressure systems. Two common methods for pressure testing are hydrostatic and pneumatic tests. Hydrostatic testing involves using water as a medium, while pneumatic testing utilizes a compressible gas to achieve the desired pressure. Compared to hydrostatic testing, pneumatic testing poses greater risks and hazards. Pneumatic tests require higher energy to achieve the necessary pressure, which is stored in compressed gas and can lead to explosive releases if the system fails.
[4] Compared to hydrostatic testing, pneumatic testing poses greater risks and hazards. Pneumatic tests require higher energy to achieve the necessary pressure, which is stored in compressed gas and can lead to explosive releases if the system fails. Consequently, pneumatic testing carries a significant risk and necessitates additional safety measures, such as pressure relief mechanisms and higher-rated enclosures. Moreover, these conventional methods of pressure testing are time-consuming and costly, requiring repetitive testing during new equipment installation, repairs, alterations, or routine maintenance.
[5] Thus, in light of the above-stated discussion, there exists a need for an improved tool and method to test the integrity of pneumatic rams before their installation on submarines, addressing safety concerns, reducing risks, and optimizing time and cost efficiency.
