Fire-fighting special steel mesh skeleton composite pipe, quality standards

Core performance indicators of fire composite pipes meeting standards

The quality of the fire-fighting special steel mesh skeleton composite pipe must first meet the special performance requirements of the fire scene. The nominal pressure needs to match the fire water supply pressure standard of the engineering design. The skeleton layer is made of high-carbon steel wire interlaced braided molding, which is closely combined with the inner and outer layers of polyethylene substrates, and there is no risk of peeling between layers. The flame retardant performance meets the requirements of fire protection-related standards. It is not easy to burn when encountering an open flame, and there is no dripping. At the same time, it has excellent corrosion resistance. It can adapt to various laying environments such as buried and humid. Long-term use will not cause rust and leakage of the pipe wall. The impact resistance is up to standard, and it is not easy to crack when it is collided by external forces in a

Selection and adaptation points of fire pipes

When selecting a project type, it is necessary to screen and adapt the specifications according to the laying scene, working pressure and other parameters. For buried pipelines, choose a model with wall thickness that meets the requirements of buried depth load. For overhead laying pipelines, consider UV resistance to avoid long-term sun aging. When selecting a model, choose products with formal test reports first, check whether the performance parameters meet the fire protection pipeline use standards, and do not choose non-standard products for cost reduction to avoid safety hazards such as pipe bursts and leakage in later pipe network operation.

Compliance construction guarantee performance landing

Qualified products also need to cooperate with standardized construction to give full play to their performance advantages. Fire-fighting special steel mesh skeleton composite pipes are preferentially connected by electric melting. During construction, the heating temperature and duration are strictly controlled to avoid virtual welding and over-welding problems. Before laying, sharp stones and metal debris in the trench need to be cleaned to avoid scratching the pipe wall. After construction is completed, the water pressure test is carried out in accordance with the acceptance specifications for fire pipelines. After the segmented pressure test is qualified, the overall pressure test is carried out to confirm that there is no leakage and no deformation, and then the acceptance is completed. The relevant test records are retained for subsequent operation and maintenance.
