Fire piping
Based on the layout characteristics of fire pipes in parking lots and basements, the core product of cast pipe fittings plays a key role at different nodes:
Bend: At the turning point of the parking lot lane and the avoidance area of the basement beams and columns, 90 degree and 45 degree bends can achieve flexible turning of the pipeline and reduce water flow resistance. For example, when installing sprinkler pipes around columns in underground garages, using large curvature radius elbows can reduce local head loss and ensure the outlet pressure of the sprinkler head.
Tee and cross: used for diverting fire main pipelines to sprinkler branch pipes and fire hydrant branch pipes. In the fire zoning of large underground parking lots, three-way fittings can supply water from the main pipeline to the branch pipes in different zones, while the four principles are applicable to the cross shaped pipeline branch nodes, ensuring the even distribution of fire water in each area.
Reducing pipe: At the connection between the basement fire pump outlet and the main pipeline, or at the transition point of the parking lot main pipeline to the end sprinkler branch, reducing pipes can achieve smooth connection of pipes with different diameters, avoiding water flow disorder and pressure loss caused by sudden changes in diameter.
Flanges and pipe fittings: Flanges are commonly used for connecting equipment such as fire pumps and valves to pipelines, and are easy to maintain and repair in the basement equipment room; Quick couplings can be quickly assembled during temporary fire pipeline laying in parking lots to meet emergency firefighting needs.
Pipe cap and plug: used for sealing the end of pipelines or reserved interfaces to prevent impurities and accumulated water from entering the pipelines in damp underground environments, ensuring that the fire protection system is always available.
