Precautions during filling and unloading of LPG tanker
Liquefied gas tanker, also known as LPG carrier, is a special vehicle used to transport liquefied gases such as propane, propylene, dimethyl ether, liquid ammonia, methylamine and acetaldehyde. The safety management of LPG tanker filling and transportation is an important link to determine LPG transportation safety and avoid gas leakage, fire, explosion, personal injury, environmental pollution and other problems. How to correctly and normatively complete the filling of LPG tank cars? Let‘s understand the precautions in the filling and pouring process of LPG tank cars.
1. When pressurizing the tank car, the operator shall not leave his post to prevent the pressure from being too high.
2. When connecting and removing hoses, it is forbidden for two people to operate two vehicles at the same time. One person must be responsible for connection and the other for monitoring and confirmation.
3. It is forbidden to discharge the pressure of the tank car during the liquid guiding process. The liquid guiding must be stopped first, and the vent valve can be opened slowly after the liquid in the tank is stable.
4. Before removing the hose, the pneumatic valve must be closed, and the control button of the pneumatic valve must be turned to the closed state.
5. When a large amount of liquid leaks from the outlet, and the operator can‘t go into the rear compartment to close the pneumatic valve at that time, Enrico LNG tanker is equipped with an emergency pneumatic control valve in the middle of the tanker, which can close three pneumatic valves in the rear compartment at the same time to block the leakage of liquid.
Standardized and reasonable operation and inspection in strict accordance with steps and regulations can effectively ensure the safety of LPG transportation and filling and avoid accidents. Safety production specifications for liquefied gas tank cars:
1. Strict quality inspection: 100% radiographic inspection for class A and B welds, class II qualified; 100% magnetic particle inspection for class C and D welds, class I qualified;
2. The anti-corrosion coating on the surface of the liquefied gas tank car adopts advanced processes such as sand blasting, rust removal, spraying and purging, so that the paint on the tank surface is durable and not easy to corrode!
3. The structure is reasonable, safe and reliable, easy to operate and easy to maintain. Strictly adopt scientific and advanced construction technology to ensure the lowest shrinkage and the highest dimensional stability under low temperature.
4. The tank body is equipped with traction pins, traveling mechanisms, legs, safety valves, liquid level meters, emergency shut-off valves, valve boxes, side rails and other accessories. In order to facilitate user loading and unloading, valve boxes are set on both sides of the tank car, and users can carry out loading and unloading operations on both sides of the car according to actual needs.
The design and manufacturing process of liquefied gas tank cars determine the quality and service life of tank cars. Choosing LPG tank cars with excellent performance can also save time, money and worry for your transportation business. Therefore, it is very important to choose powerful manufacturers with perfect quality assurance system. Chengli special purpose vehicle Co., Ltd. is your best choice because of its strong technical force and advanced and complete production equipment.
