The bending of cryogenic pipes is usually caused by the following reasons:
Pipe Turning Design and Layout
This is one of the main reasons for pipe bending and laying. During the design and placement of piping systems, piping turn design may be required to accommodate specific terrain, building structures, or other equipment needs.
Undulation of terrain
Undulating terrain is another cause of curved laying of pipes. In complex terrain such as mountains, hills, or rivers, in order to maintain the continuity and stability of pipelines, it is necessary to bend and lay pipelines according to terrain changes.
Pipeline expansion and contraction problems
Due to the special properties of pipeline materials, pipelines will have expansion and contraction problems when they expand and contract in hot and cold contraction. When the pipeline is affected by high temperature, low temperature, thermal cycling, etc., it may elongate or shorten, which will lead to a certain bend in the pipeline.
Factors in the manufacturing and installation process
During the manufacturing and installation process, the pipe may be subjected to forces such as stretching and twisting, resulting in bending of the pipe. In addition, it can also cause pipes to bend if they are not properly aligned and secured during installation.
The bending of cryogenic tubing can have an impact on the entire fluid transfer system. First, bending changes the direction and velocity of the fluid in the pipe, resulting in increased resistance. Secondly, bending will cause the fluid to rotate, and the rotation will increase the energy consumption of the fluid, so that the efficiency of transmitting energy will decrease. Finally, bending can easily accumulate sediment, damage pipes, affect conveying quality, and even cause system failure.
In order to ensure the normal operation of the cryogenic fluid transfer system, the bending of the pipeline should be avoided as much as possible. If bending is necessary, a design with a small bending angle and a large bending radius should be chosen, and the internal cleaning and maintenance of the pipeline should be strengthened. During installation and use, it is also necessary to pay attention to controlling the changes in parameters such as temperature and pressure to avoid excessive stress on the pipeline.
