1, single pipe drainage and exhaust.
High-rise building does not need exhaust standpipe, single pipe to achieve exhaust and drainage. A spiral water flow is formed through the inner blades of the pipe fittings, and the water pipe is connected with the pipe wall to rotate, decelerate and exhaust, and form hollow exhaust at the same time.
2, saving costs and space.
由于省去了排气管系统，所以节省了排气管和管件的成本，减少百分之五十管 道井面积。可有效连接U-PVC，ＨＤＰＥ，铸铁管材，给开发商及代理商更多选 择．
Because the exhaust pipe system is omitted, the cost of the exhaust pipe and the pipe fittings is saved, and the area of the fifty percent pipeline well is reduced. Can effectively connect U-PVC, HDPE, cast iron pipe, to developers and agents more choice
3, to solve the noise, bathroom odor,
Because the water in the standpipe is stuck in a swirling shape, the noise is very small. The utility model can adjust the positive negative pressure in the pipe, and effectively solves the peculiar smell phenomenon in the toilet.
4, slender, light weight, long life.
与传统排水系统相比，要达到相同排水效果时管件直径更小。因为管径小，没 有排气管，排水系统重量自然轻。由于卓越的防腐性能，使产品使用寿命比一 般铸铁管件使用寿命更长久。
Compared with the traditional drainage system, the pipe diameter is smaller when the same drainage effect is achieved. Because the pipe diameter is small and there is no exhaust pipe, the drainage system is light in weight. Because of the excellent corrosion resistance, the service life of the cast iron pipe is longer than that of the common cast iron pipe.
5, installation and maintenance more simple.
单管系统安装和维修都更方面简捷，又节省了安装人工和费用成本。安装时就 可以逐层检测，不存在双管系统安装中排水和排气管道配合的问题，每套系统 每层只需要打一个安装孔，并且可以通过压力检测口接头逐层安装，逐层检查 ，保证系统安装质量。
Single pipe system installation and maintenance are more simple and convenient, but also saves installation costs 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.
6, pressure resistance, seismic resistance, corrosion resistance.
In addition to the unique drainage technology, as well as a good casting and heat treatment process and strict quality inspection, cast iron parts have better pressure resistance, more suitable for high-rise buildings. Shockproof requirements can reach 30 degrees angle, no leakage and leakage. Both inside and outside surfaces have antirust coating with a thickness of 0.8mm, which has high acid and alkali corrosion resistance.
