Water pipes are something we often encounter, and force transmission joints are equipment connected to the pipeline to maintain the normal operation of the pipeline. Force transmission joints also play an important role in city gas pipelines. When choosing a power transmission joint, the following three questions should be paid attention to:

1. Major issues. Nowadays, many gas companies choose steel power transmission joints, which generally have the advantages of corrosion resistance, strong pressure resistance, and resistance to interference. According to the rules of "City Gas Design Code", this project allows the use of stainless steel power transmission joints, and different power transmission joints can be selected according to the site environment and factors.
2. The settlement of high-rise buildings. Generally speaking, the settlement rate of high-rise buildings is relatively high within 5 years after completion, and then gradually decreases. Gas pipelines are usually installed at the beginning of construction, but they will cause building settlement in the later stages of construction. Because of the weight of high-rise buildings, it is necessary to choose loose-fitting force-limiting nodes with good safety performance and reliable quality when selecting force transmission nodes.
3. Additional head questions. The taller the high-rise building, the longer the gas pipeline, but the density of air and air are different, and a rated pressure head will occur in the pipeline. When some users use gas, they will be greatly shaken. Exceeding the normal shaking range affects the normal operation of the user's burner, resulting in the incomplete combustion of gas. Therefore, controlling and eliminating the influence of the additional pressure head is an important element that must be considered when selecting a force transmission joint.
