Introduction: With the gradual arrival of summer, under the influence of climate temperature, industrial production pipeline, civil drinking water pipeline, waste water treatment pipeline, etc. in high temperature weather, due to the thermal expansion and cold contraction of steel, when the temperature of material block rises, the molecular heat movement is violent, resulting in the expansion and contraction of pipeline

With the gradual arrival of summer, under the influence of climate temperature, industrial production pipeline, civil drinking water pipeline, waste water treatment pipeline, etc. in high temperature weather, due to the thermal expansion and cold contraction of steel, when the temperature of the material block rises, the molecular heat movement is fierce, resulting in the pipeline Expansion joint How can people prevent this kind of problem?
1. Heat resistance mainly avoids cracking and stickiness caused by hot summer temperature and strong direct sunlight. Once the crack is found, the expansion joint products applied on the equipment shall be removed and replaced immediately to ensure the normal operation of the equipment.
2. People's staff need to carry out regular inspection in winter and summer, and remind enterprises and manufacturers that have applied and prepared to apply expansion joints again.
3. In hot weather and high temperature weather, it is necessary to improve the application of expansion joint for water supply and drainage pipeline installation. Try to reduce the sun and sun exposure, and cover the expansion joint as much as possible, such as using shading cloth and sunshade, so as to avoid damage of expansion joint and causing economic loss.
4. In application, the installation length should be adjusted according to the required length. Generally, the length of the expansion joint can be well adjusted by adjusting the upper nut according to the application drawing. Under the condition of achieving the required compensation, the gland bolt and nut on the top can be adjusted to play a good sealing role.
   Telescopic device It is a new product of connecting pump, valve, pipeline and other equipment with pipeline. According to the full bolt, they are connected to make it become a whole, and there is a certain displacement, which is convenient for installation. It can bear the axial working pressure of pipeline. In this way, it can be adjusted according to the size of field installation during installation and maintenance. In the work, it not only improves the work efficiency, but also plays a certain role in protecting the pump, valve and other pipeline equipment.
