Application of the liquid propane tank trailer
The propane is the main component for liquid petroleum gas. The propane gas turns into liquid when it is pressured. The pressure vessel is to container the liquid propane, as a liquid propane tank trailer. The tank pressure is different in different countries, the design pressure is around 1.55 Mpa in European countries and American, the design pressure in China is 1.77Mpa. After the tank complete, we will do the pressure test, including the hydro test and air test to test tank welding and strength.
Description of the liquid propane tank trailer
This 49000L liquid propane tank trailer strictly complys with our national fabrication standard for safety issue. On top of the tanker, there is a spring type device. The safety valve can automatically open to discharge gas when tank pressure is higher than the design pressure. When the tank pressure goes back to the normal range, it shut down automatically. The emergency cut-off valve is installed in the bottom of the tanker, gas phase has one valve and liquid phase also has one valve. The function is to quickly cut off the gas phase and liquid phase incase of any emergency within 10 seconds. The operating hand is located in the valve box.
Liquid level gauge
There is a liquid level gauge in rear of tanker. There are ball float type and rotary type.The ball float type is the popular one.
There is a hollow ball which is floating on the surface liquid inside the tank, the rise and fall of liquid surface will rise or down the ball, which will reflect on the gauge outside. This only can read the height of the liquid inside the tank.
The volume and weight
The density of propane normally is 420 kg/M3. The filling capacity in tons= volume X propane desity(0.42). 56.11 m³ taken as an example: the filling in tons:56.11X0.42=23.56Tons. Since LPG is a mixture gas, the purity and density is different in different area. Please refer to actual filling tons is real situation.

Hubei Huilong Special Vhielc Co.,ltd has independent workshop for pressure vessel. There is stress relieving heat treatment room to relieve the extra stress of the tanker after thank complete. The X-RAY machine will check the tank welding seam one by one to ensure there is no welding failure. All our production step and inspection step make sure the 100% qualified products for the pressure vessel.
