How to choose pipes for siphon drainage system

We, siphon rainwater drainage installation requires pipes, so we need to be very careful when choosing pipes. Only when the pipes and the drainage system are well matched can the maximum drainage capacity of the drainage system be brought into play. Generally, before installing the siphon drainage, we have to perform a hydraulic calculation first, so that we can determine what kind of pipes need to be installed. Then, below, Yitong Siphon drainage will show you how to choose drainage pipes.

At present, there are many varieties in the pipeline market, but there are not many pipelines that can be used in siphon drainage systems. The most common types are iron pipes, steel pipes, and stainless steel pipes. Before we make a selection, we must first determine what the siphon rainwater bucket looks like. The pipe we choose must be connected to the siphon rainwater bucket. It is best to use the same material pipe, which has a lot of installation. The convenience is also conducive to later maintenance and maintenance. At the same time, we have to choose the pipe material according to the construction requirements and characteristics of the installation of siphon rainwater, taking into account the working pressure and economic efficiency of the system and other comprehensive factors.

Siphon drainage system

When installing siphon drainage pipes on the roof, iron pipes, steel pipes, stainless steel pipes or high-density polyethylene pipes should be used. As we have mentioned above, the pipes and fittings must be made of the same material as the connecting pipe of the siphon rainwater bucket, so as to facilitate installation and later maintenance. In addition. The selection of pipe materials should also meet the characteristics and requirements of the building, and comprehensively consider various factors, such as the working pressure of the system, fire prevention and disaster prevention, noise reduction, ease of installation, and most importantly, economic efficiency. It must also comply with national standards,

There are many precautions for siphon drainage. In the installation process, the cast iron pipe connection is best to use the clamp type, and the stainless steel pipe and the steel pipe connection can be welded, flanged or grooved. Welding and flange connection should be galvanized twice. HDPE pipes and fittings are connected by hot-melt butt welding or electrofusion, and the connection between the pipe and the rainwater bucket should be electrofusion.

When stainless steel pipes are used for the siphon rainwater system, the corresponding rainwater bucket is a stainless steel outlet pipe. When HDPE pipes are selected for the siphon rainwater system, the corresponding rainwater bucket and the outlet pipe bucket are the HDPE pipe outlet pipes. The so-called "a good saddle with a good horse" is actually the truth, the choice of rainwater bucket should have what kind of pipeline to match it.
