There are advantages such as unparalleled lifespan compared to cast iron pipes; In construction, it has the characteristics of light weight, easy handling and installation, and simple connection. A-type ventilation caps are widely used in civil building drainage and sewage, chemical drainage and sewage, rainwater drainage and other fields.
Characteristics of A-type ventilation cap:
1. The surface hardness and tensile strength of the pipe are excellent, and the pipeline coefficient is high.
2. Good performance, with a normal lifespan of over 50 years.
3. Pipelines have excellent performance in handling inorganic acids, alkalis, and salts, and are suitable for industrial wastewater discharge and transportation.
4. The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.
5. The material has a high oxygen index and self extinguishing properties.
6. The coefficient of expansion of the pipeline is small, at 0.07mm/m ℃, and the deformation is less affected by temperature. The thermal conductivity and elastic modulus are small, and compared with cast iron drainage pipes, the frost resistance is excellent.
7. Pipes and fittings can be connected by bonding, with simple construction methods, easy operation, and high installation efficiency.
Application scope of A-type ventilation cap:
Industrial and civil building indoor and outdoor drainage pipeline engineering, continuous discharge of domestic sewage temperature not exceeding 40 ℃, instantaneous discharge of sewage temperature not exceeding 80 ℃; Industrial wastewater that does not corrode pipes can also be used.
