The characteristics of materials used in the making of Borescopes can be studied with respect to the tensile strength, heat resistance, pressure endurance, rustproof and resistance to the corrosive external elements. These are applicable to the external body structure of the Borescopes. Mostly they are made of steel, brass, copper and their combinational alloys. The manufacturing methods include molding, blowing, casting and sheet drawing processes. The metals are cast into heavy molds in which they get through slow heat treatment. They are cooled at gradually reducing temperature to ensure maximum value for all the characteristics explained above. The treatments of other materials vary depending on their intended purpose and their basic characteristics.
Borescopes Functional Units
- Probing Assembly: – The probing assembly is one of the main functional units of the Borescopes. This is made of soft steel tube with a diameter varying from 0.5mm to 8mm, depending on the model of the Borescopes. This is the unit which houses the objective lens, articulation control, braid and the controlling levers for the probe. At the tip of the probe you might find the connectivity to the CMOS chip of the camera. The images captured from the lens are intelligently transformed into camera readable format and sent to the device. The CMOS chip also performs many other operations like the image formatting, resolution enhancement and brightness increment. The objective lens can work effectively to cover distances over 10 meters depth within the pipes and cylinders. The entire assembly is placed inside a steel chamber made of heat and pressure resistant characteristics.
- Camera Housing: – The camera housing assembly of the Borescopes is made from steel or brass materials. The system is waterproof in nature and it can go to a depth of 150feet and below for the inspection of underwater surfaces. In fact the complete Borescopes assembly is made up of solid steel and brass combination to withstand highest pressure.
- Battery Housing: – The battery housing of the Borescopes is made of water and shock proof materials. They could be made from the combination of steel, fiber and anti-magnetic property materials.
Borescopes LED Protection Shield
The LED protection shield is made of heat absorbing materials which can also protect the assembly from explosion. The characteristics are highly required when the Borescopes is used for inspecting the pipes containing fire and heat sensitive liquids. The heat emitted by the LED is effectively absorbed by the protective layers over the assembly.
Borescopes Cable Protection
The external cable which leads the Borescopes on their way is protected by a thick shield of pressure and corrosion resistant material. When this is extended to more than 250 meters in length the waterproof layer of the cable automatically covers the entire length and diameter. Moreover the flexible cable can hold on to its position in extreme conditions wherein the water velocity is very high. The cable protective layer also has shockproof nature for absorbing the vibrations caused by the water velocity. This will help in keeping the Borescopes stationary during inspection.
