Uncontrolled water can be the most lethal weapon in this world. The power is often displayed by the strong jet of water sprayed to disperse crowds. While the calm waters are soothing to the senses and we often go to the beaches for relaxing, there are certain areas where we never welcome water. For instance on ships and submarines, water is best as long as it is kept outside. If water enters in them then there is no stopping to the catastrophe that follows.

The submarine is one of the most powerful weapons used by the Navy of the United States. The huge fleet of the submarines owned by the country is one of the finest available today. They are not only expensive, but they are also well equipped and have a fair number of crew in them.

Keeping an eye out for anything fishy, these submarines are always present in the depths of the waters. It is a perfect example of strength below the water as long as it is perfectly waterproof. While a submarine may look very cool under the water, it is not an easy job to keep it that way. The constant exposure to water is lurking threat for leakage. If by any chance the paint gets chipped off even in a centimeter, it becomes the only reason for the biggest loss in the Navy. The paint is present to protect the steel beneath so that there is no chance of corrosion.

It is not possible for the paint to never peel off. There are many reasons which can damage the paint and minute holes are formed which make the shell weak. When the submarine dives into the depths of the oceans, the pressure on its shell increases many hundred times. This is when these minute holes become active and let the water to enter. With the hatch cover ultrasonic tightness testing procedure the crew finds these minute holes and keep repairing them whenever they are found.

It is not a tough task with the help of the ultrasonic leak detector at hand. It is a simple task of scanning the body with the ultrasonic leak detector. As soon as a leak comes beneath the sensor, it produces a pulse which indicates to the staff about the presence of a hole. The hole in the body is never missed by the gadget because of the simple rule it follows.

Tightness of hatch with ultrasound is checked daily for every submarine. It is not just a precautionary procedure, but it is also a part of their daily duties. This routine helps the navy to maintain a fleet of submarines that are always ready to participate in a battle no matter when the need arises.
