Many people can see a drain pipe under the washbasin when they use the toilet at home. Actually, this is a drain pipe. But readers, are you familiar with drainage pipes? In fact, we often come into contact with drainage pipes in daily life, and there are many specifications of drainage pipes. It is also very helpful for us to understand the specifications of drainage pipes. Next, let's get to know each other through Bian Xiao's introduction. So, what are the specifications of the drain pipe?

What is the specification of the drain pipe?

(1) The diameter of the drainage branch pipe connecting the washbasin, washbasin, bathtub and sanitary basin is dn32 (sewer pipe diameter is 32mm), and dn40 (sewer pipe diameter is 40mm) can be used for larger ones.

(2) The diameters of drainage branch pipes connecting urinal and urinal are dn50 (sewer pipe size is 50 mm) and dn75 (sewer pipe size is 75 mm).

(3) The diameter of the drain pipe connected to the toilet is dn 1 10 (the size and diameter of the drain pipe are 1 10 mm).

(4) The diameters of the horizontal drain pipe and vertical drain pipe connected to the urinal should not be less than dn 1 10 (the diameter of the sewer pipe is 1 10 mm).

(5) The diameter of urinal drain pipe or drain pipe connecting more than three urinals shall not be less than dn75 (the diameter of sewer pipe is 75mm).

(6) The drain pipe diameter of sewage pool and washbasin in the hospital is not less than dn75 (the drain pipe diameter is 75mm).

(7) The diameter of the drain pipe of the washing pool and sewage pool in the canteen and restaurant should not be less than dn75 (the size and diameter of the drain pipe are 75mm). * * * canteen, dining room. The diameter of the drainage branch pipe of the public toilet is not less than dn75 (the sewer pipe diameter is 75mm), and the diameter of the main pipe is not less than dn 100 (the sewer pipe diameter 100mm).

(8) The diameter of the indoor drainage riser is not less than dn75 (the size and diameter of the sewer pipe are 75mm).

Material type of drain pipe

1, PE .PE, commonly known as polyethylene, is specially used for building water supply, drainage, gas pipelines, heating, electrical, agricultural and industrial materials. In modern society, PE is mainly used to supply water and drainage to cities. The main characteristics of PE drainage pipe material are chemical resistance, good hygiene, good flexibility, impact resistance, convenient and simple operation, etc.

2. PVC. PVC, commonly known as polyvinyl chloride, is a polymer material. It is also the most unique drain pipe material. Polyvinyl alcohol is a thermoplastic resin formed by polymerization under the action of vinyl chloride initiator. It is one of the largest plastic products on the market at present, with low cost and wide application range. Generally, PVC drainage pipes are made of white or light yellow.

3. PP .PP, formerly known as polypropylene, is a material specially used for drainage pipes. Its main characteristics are high hardness, heat resistance, no aging and relatively low density. The temperature environment used can reach about 100 degrees, but at lower temperature, the material of PP drainage pipe will become brittle. In addition, it has good insulation and electrical properties.

4. Plastic. The material of plastic itself is relatively light, with good impact resistance, corrosion resistance, transparency and wear resistance, so this drainage pipe material also has high practical value in the field of modern construction engineering.

5, stainless steel. Stainless steel, the word must be familiar to everyone! Stainless steel, as its name implies, is a kind of steel pipe that will not rust. It is mainly used to transport fluids, such as water, oil, pure gasoline and natural gas. Moreover, this kind of drainage pipe material is used very frequently in China, and its scope is also relatively wide. It has high torsional strength and light weight.

The above is a detailed introduction to the specifications of the drainage pipe. After reading the above, we know that the drainage tube is effective, and many friends like it very much. Everyone should pay attention to the choice of specifications when purchasing drainage pipes, otherwise it is not worth wasting. But we should also pay attention to the material of the drain pipe and choose the appropriate material of the drain pipe. After reading the article, everyone has a deep understanding of the drainage pipe, and interested readers can rest assured to buy it.
