Description

Technical Field

[0002] Currently, in the construction industry, the installation of fire protection pipelines is an important link, which not only relates to the safety of buildings but also directly affects the lives of people in the event of a fire. Traditional fire protection pipeline installations mostly adopt the method of fixed brackets combined with welding or threaded connections. Although these traditional methods can achieve certain functions, they have obvious deficiencies in terms of construction efficiency, convenience of later maintenance, and seismic performance. With the enhancement of social awareness of fire safety and technological progress, how to improve the quality and efficiency of fire protection pipeline installation has become the focus of attention in the industry.

[0003] Specific solutions of the prior art: Fixed brackets plus welding: This method is relatively simple and crude. The pipeline is fixed at a predetermined position through welding, but the welding points are prone to become stress concentration areas, resulting in cracks or even fractures after long-term use, and it is difficult to repair. Threaded connection: Compared with welding, threaded connection is more flexible and convenient for disassembly and assembly. However, due to the design limitations of the thread itself, the connection strength is limited, and there is a risk of leakage, especially for fire protection water pipelines operating in high-pressure environments. Flange connection: Flange connection provides higher sealing performance and connection reliability and is suitable for use in large-scale engineering projects. However, the cost is relatively high, and the installation complexity increases.
