Prototype research of LPG tank using GPI standard pipe (J)

Abstract

A prototype LPG tank using GPI standard E10 grade was studied. As a result, when comparing the weight of the steel tank and its own weight, the 10 kg tank was reduced from about 12.1 kg to 3.3 kg (about 1/3), and the 20 kg tank was from 18.9 kg to 5.3 kg (about 1/3). As a result, it was confirmed that the gas filling weight ratio was reduced by about 40%, making handling easier. In addition, compared to metal tanks, production costs are expected to be halved due to the use of GPI standard mass production parts due to the structure of the pipe tank. Regarding safety, it is possible to use the heat softening low melting point safety valve that is always installed in the metal tank, but the GP-LPG tank has adopted a quality assurance program from the RTC8 screw assembly structure for the caps on both ends of the pipe, and the remaining amount of screw is managed. And the pressure-resistant breaker ring interior provides a more secure combustible gas leak and emergency release breaker function. In terms of durability, FRP materials do not suffer from stress corrosion cracking, which is a drawback of metal materials.
