2. Self-sealing fuel tank - Wikipedia

   en.wikipedia.org/wiki/Self-sealing_fuel_tank

   Self-sealing fuel tank. A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber ...

3. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...

4. Wet wing - Wikipedia

   en.wikipedia.org/wiki/Wet_wing

   Wet wing. A wet wing (also referred to as integral fuel tanks[1]) is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. The use of wet wings has become common among civilian designs, from large transport aircraft, such as airliners, to small general aviation aircraft.

5. External floating roof tank - Wikipedia

   en.wikipedia.org/wiki/External_floating_roof_tank

   External floating roof tank. An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level ...

6. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Crimped or pressed connections to use special fittings permanently attached to tubing with a powered crimper. The fittings, manufactured with a pre-installed sealant or O-ring, slide over the tubing to be connected. High pressure is used to deform the fitting and compress the sealant against the inner tubing, creating a leakproof seal. [32]

7. Fuel tank - Wikipedia

   en.wikipedia.org/wiki/Fuel_tank

   Once the soldering, brazing or welding is complete, the fuel tank is leak-tested. [1] In the aerospace industry, the use of Fuel Tank Sealants is a common application for high temperature integral fuel tanks. This provides excellent resistance to fluids such as water, alcohols, synthetic oils and petroleum-based hydraulic fluids. [2]
