Liquid ammonia is a special, irritating and toxic gas. It is very easy to cause explosion and spontaneous combustion in the process of liquid transmission, which will cause environmental pollution, casualties and property losses. As early as 2008, the state issued instructions for this type of transportation of hazardous chemicals, requiring the suspension of the use of hoses to transport a series of chemical liquids and gases such as liquid ammonia. The use of liquid ammonia universal joints for the loading and unloading of liquid ammonia can meet the various angles of steering during the loading and unloading process, and the liquid ammonia loading universal joints (crane tubes) are made of metal materials to ensure the loading and unloading of liquid ammonia There will be no leakage accidents in the middle, which improves safety. Therefore, nowadays, in order to prevent dangerous accidents during transportation, the universal joint (crane tube) of liquid ammonia loading truck plays an important role.
The universal joint for liquid ammonia loading is one of the crane pipes. The crane pipe is a very important equipment in the petrochemical storage and operation industry. It is connected in series with the pipeline by a rotating joint with flexible rotation and good sealing. Between the truck and the trestle bridge storage and transportation pipeline, the liquid medium is transferred, and the universal joint is one of the elbows. A universal joint is very similar to a human joint, and can be changed within a prescribed range by the angle between the pipes or other elbows connecting the universal joint.
