Common Problems Existing in the Inspection of Hazardous Chemical Atmospheric Tank Trucks

May. 11, 2022

In recent years, the number of atmospheric pressure tankers for dangerous goods in my country has been increasing, and all kinds of accidents caused by tank trucks are also increasing rapidly. During the inspection of tank trucks, relevant departments should carefully review the relevant documents of various atmospheric tank trucks, carefully check the safety of various parts of the atmospheric tank truck, etc., to ensure the safety of hazardous chemicals during the transportation of atmospheric tank trucks.

(1) Lack of complete original data

At present, my country has issued relevant regulations on the transportation of hazardous chemicals. Various documents require users to provide various transportation materials such as product quality certificates and transportation tank safety certificates to the unit responsible for inspection when entrusting inspections. However, in the actual inspection process, many users can only provide the driver's own driving license, etc., and cannot provide complete information about the atmospheric tank truck. Most of the units responsible for inspection use various information on the driving license and nameplate to ensure that the data of each inspection item in the inspection results are consistent with the cargo of the atmospheric tank truck.

(2) Cracks appear in the tank body of the atmospheric tank truck

Another common problem in the inspection of hazardous chemical atmospheric tankers is cracks, but most of this occurs on one side of the tank body of the atmospheric tanker. This is because the welding of the tank body and the tanker When the bottom frame is not fully welded or undercut, it will cause cracks in the tank; and there is a big difference between the total load of the Chemical Tank Trailer and the total load of the tank truck, and some users often appear "large tank and small tank" when loading. The phenomenon of "marking" occurs, and the problem of overload occurs, so that the connection between the tanker and the tank body needs to bear a large stress load. Therefore, when inspecting the atmospheric pressure tanker of hazardous chemicals, it is necessary to carefully check the volume, size, and weight that can be carried on the atmospheric tanker, and the method of "water volume" should be used during the inspection process. At the same time, it is necessary to clearly state the maximum load capacity of the atmospheric tank truck.

(3) The safety accessories of the atmospheric tank truck lose their original effectiveness

For hazardous chemical atmospheric tank trucks, if you want to ensure the normal and safe operation of the vehicle, it is necessary to ensure that the safety accessories are intact. In many cases, the atmospheric tank truck needs to operate in a high temperature or humid environment, and it has to bear the damage of the alternating load. Therefore, it may cause problems such as leakage or loosening of the safety accessories. If the breathing valve is installed on the tank top or manhole cover of the tanker, the breathing valve is used to adjust the pressure difference between the inside and the outside of the tank. This method can adjust the air pressure in the tank to a balanced state, and can also block the volatilization of the medium. In the process of inspection, there will be problems that the quality of the breathing valve does not meet the requirements. If you encounter

In case of sudden problems, the staff should cut off the breathing valve as soon as possible, so that it can achieve the purpose of protecting the tank.
