LPG Gas Cylinder Tensile Test
14 August 2024
During the welding process, the material of the liquefied gas cylinder tends to harden, making it unable to adapt to the expansion and contraction after the liquefied gas is injected. Therefore, all welded liquefied gas cylinders are placed into a furnace for heating and softening. After completing this production process, workers will randomly take a sample and cut open the liquefied gas cylinder, slicing at the seam to obtain a piece of metal, which is then subjected to a bending test. If the metal does not break, it indicates that the welded joint meets the standards.
The pressure of a liquefied gas cylinder typically ranges from 0.5 to 1.2 megapascals. When its temperature reaches 40 degrees Celsius and its volume cannot change, the pressure can rise to 1.59 megapascals. For every degree increase in temperature, the pressure increases by 0.04 megapascals. When the pressure reaches 2.1 megapascals, an explosion can occur. Therefore, during daily use, it is important to avoid safety hazards caused by excessive environmental temperatures.
