Installation process of seismic pipe rack support
The support of seismic pipe gallery is one of the main equipment to improve the urban comprehensive defense ability, which can be widely used in the seismic fortification of electrical engineering and related buildings. The key use of this equipment is also an important task of earthquake prevention and disaster reduction at present; In some buildings or electrical engineering construction, through the use of different types and specifications of pipe rack supports, the pipeline system can achieve the effect of seismic reinforcement.
It is also the importance of the use of pipe rack supports. According to the relevant consumption specifications, the pipe rack supports consumed by manufacturers must be able to pass rigorous tests, so that such supports must be able to pass the performance test and certification by the third party of the relevant profession. Only in this way can this equipment be guaranteed to have the purpose of maintaining the electrical or mechanical equipment of the building stably and reliably in use, In particular, in the application, the pipe rack support needs to be able to accept the force in various degrees and directions. After all, in the practical application environment, it is difficult to estimate the degree and direction of the force in that direction. In order to achieve a good effect of strengthening and stabilizing equipment, the pipe rack support needs to be able to accept the force in various degrees and directions.
In addition, according to the rule 5 in Chapter 8, the first paragraph of the Technical Standards for Urban Pipe Rack Support Engineering, the design and construction of equipment support projects can be stopped according to the main fortification category (Class B), and the requirements can meet the rules of existing national codes; It is not difficult to see from these that the importance, necessity and high demand of using pipe rack supports are proved again. In the future, qualified pipe rack supports will be widely used in various buildings or equipment construction.

Bellows can be connected with non-metallic compensator only after receiving internal pressure
When the bellows is subjected to axial pressure beyond its support, it will suddenly bend and lose the stability of linear form, just like the compression bar or cylindrical spiral spring. This is inevitable. If the internal pressure accepted by the bellows also exceeds a certain pressure value that it can support, instability will also occur. Such problems exist in elastic seals, axial expansion compensators and pneumatic butterfly valves. That is to say, the ability of bellows to accept internal pressure generally depends on its stability. When studying the stability of bellows, we can use the well-known Euler pressure bar formula to calculate its critical load. In this way, the critical load of bellows can be approximately solved by calculation.
In practice, the bellows will accept certain pressure, which requires that the bellows have sufficient pressure resistance ability. In the process of consumption, the bellows will generally be designed and tested to determine reasonable structural parameters to ensure the acceptance ability of the bellows. Therefore, when choosing and applying bellows products, you should carefully understand the critical load Design pressure and other parameters to ensure that the product meets the needs of practical working conditions.
As the projects in cities are carried out more frequently, the demand for relevant accessories is more intense, including non-metallic compensators and other products. As for the product, the completion of its design has created many theoretical foundations such as mathematics and data mechanics. Of course, considering the different uses of details, we naturally pay attention to different points when designing. In order to ensure adequate compliance, relevant performance tests are unavoidable.
Therefore, the non-metallic compensator often stops some detailed tests before stopping the detailed application, mainly including the following contents: First, the stress calculation of the non-metallic compensator is a very important content. The test of this performance is mainly to test its strength characteristics, which is related to whether the future application can be guaranteed. Second, the pressure resistance test is also an important content. The main consideration is what kind of pressure bearing ability the product has in the face of pressure.
