Because of the advantages of material saving, large drainage flow and other advantages, the special single riser system makes up for the shortcomings of the common single riser and common double riser. This is the power of science and technology is also the inevitable social development, excellent system to replace and eliminate backward systems, the prospects of the special single pipe system will contribute to the construction of social urbanization and its due strength.
1, drainage and exhaust pipe. High-rise buildings do not need exhaust riser, a single pipe exhaust and drainage. The inner wall of the pipe fitting is formed into a spiral water flow, and the water flow is pasted on the wall of the pipe to rotate and decelerate to discharge.
2, save cost and space. Because the exhaust pipe is omitted, the cost of the exhaust pipe and the pipe fitting is saved, and the whole drainage system occupies only one space of the drainage pipe. At the same time, the system noise is very low.
3, pressure, shock resistance, corrosion resistance. In addition to the unique drainage technology, as well as good casting and heat treatment process and strict quality inspection, cast iron parts better pressure resistance, more suitable for high-rise buildings. Seismic requirements can be reached around 30 degrees angle, no leakage and leakage. Both inside and outside the surface of the thickness of 0.8mm antirust coating, high acid and alkali corrosion resistance.
4, thin, light weight, long life. Compared with the traditional drainage system, to achieve the same drainage effect when the pipe diameter smaller. Because the pipe diameter is small, no exhaust pipe, drainage system weight light. Because of its excellent corrosion resistance, the service life of the product is longer than that of the cast iron pipe.
5, installation and maintenance easier. Single pipe system installation and maintenance are more simple, but also saves the cost of installation and labor costs. The installation can be layered detection, there is no problem of drainage and exhaust pipe installation with pipe system, each system each layer only need to make a mounting hole, and through pressure testing joint layer layer installation, inspection, installation quality assurance system.
