LPG (Liquefied Petroleum Gas) tank semi trailers are designed to transport propane, butane, and other liquefied petroleum gases safely and efficiently. These trailers are built to withstand high pressure and ensure secure containment of the LPG during transportation. The tanks are constructed from high-strength steel or aluminum to handle the pressurized nature of LPG. These trailers are widely used in industries such as energy, construction, and automotive sectors. They are critical for the transportation of LPG from production plants to distribution points, where it is then used for heating, cooking, and fuel in vehicles. 

The LPG tank semi trailers are equipped with features like vapor recovery systems, pressure relief valves, and safety baffles to minimize the risk of accidents and ensure the secure transport of gas. Additionally, these trailers are designed to comply with international safety standards and regulations, ensuring their use in hazardous environments.
