1, single tube drainage and exhaust. The high-rise buildings do not need exhaust pipe, exhaust and drainage tube to achieve. Through the pipe fitting internal blade to form a spiral water flow, the water flow is attached to the wall of the tube wall rotation deceleration, and the formation of the hollow exhaust.
2, save the cost and space due to the exhaust pipe, so saving the exhaust pipe and pipe cost, but the entire drainage system only accounts for a drainage pipe space. At the same time, the system's noise is very low.
3, pressure, earthquake resistance, corrosion resistance. In addition to the unique drainage technology, as well as good casting and heat treatment process as well as strict quality inspection, cast iron parts, better performance, more suitable for high-rise building. Anti vibration requirements can reach about 30 degrees swing angle, no leakage and leakage. Both inside and outside the surface have a thickness of 0.8mm anti rust coating, has a high acid and alkali corrosion resistance.
4, slender, light weight, long life. Compared with the traditional drainage system, to achieve the same drainage effect when the pipe diameter is smaller. Because the diameter is small, there is no exhaust pipe, drainage system, the weight of natural light. Because of the excellent corrosion resistance, the service life of the product is longer than the ordinary cast iron pipe.
5, installation and maintenance more simple. The installation and repair of single systems are more simple, but also save the cost and the installation of artificial. Installation can be layered detection, two pipe system installed in drainage and exhaust pipe with the problem does not exist, each system each layer only need to play a mounting hole, and through the pressure test port connector installed layer by layer, layer by layer to check and ensure the installation quality of the system
