What is the difference between the material of water supply pipe and drainage pipe?

UPVC, flexible cast iron pipe, PE double wall corrugated pipe, etc. are used for drainage pipes.

PP-R, stainless steel, steel-plastic composite pipe, hot-dip galvanized steel pipe, etc. are used for water supply.

In addition to the characteristics of light weight, corrosion resistance, no scaling, and long service life of general plastic pipes, PP-R pipes also have the following main characteristics: We 1, non-toxic, hygienic. PP-R material only molecular carbon, hydrogen, no harmful and toxic elements exist, hygienic can be *, not only used in hot and cold water pipes, but also used in pure drinking water systems.

Page 2, Insulation. Watt MK's PP-R pipe conducts heat, steel is only 1 200. Page 3, good heat resistance.

Vicat softening point of the PP-R pipe left and right. Up to about 95 degrees of water, built to meet the specifications of the hot water system requires a maximum operating temperature.

4. Long service life. The service life of PP-R pipe can reach more than 50 years under the conditions of working temperature of about 70 and working pressure (PN); Room temperature (around 20)? Up to 100 years of life.

Page 5, easy to install, connection can be *. PP-R has good weldability, pipes, pipe fittings can be melted and fused to connect, easy to install, joints can be *, the strength of its connection parts is greater than the strength of the pipe itself.

6. Can be ** material. PP-R waste is cleaned, crushed and recirculated into pipes, pipe fittings production. **The amount of material does not exceed 10 of the total amount and does not affect the quality of the product.

- The prevalence of PPR pipes, there are also some problems: the long-term use of precipitates that are harmful to health has not yet been determined.

It is understood that the international community is the most commonly used copper pipe. Brass has obvious advantages in terms of high and low temperature resistance, environmental and health resistance. The monopoly of plumbing systems in developed countries or regions.

For example, in Hong Kong, which accounts for about 70% of the copper market, the domestic water system of residential buildings must use brass according to the law. The United Kingdom and other developed countries with a high penetration rate of old copper pipes.

Thin-walled copper pipes, PPR pipes, thin-walled stainless steel pipes, etc.

In the decoration of the house, everyone is most worried about the problem of water supply pipes at home, if you do not choose the right raw materials, there will be water seepage in the future, the water pipe is broken, and it is very inconvenient to maintain it in the middle and later stages. The materials generally used for high-quality water supply pipes are:

1. PPR tube, he has a lot of advantages:

Environmental protection: The main material is random copolymer polypropylene, which is non-toxic and tasteless, and will not pollute the water source.

High temperature resistance: The temperature resistance range is about -15° 95°, which is enough to meet the temperature of household water.

Long life: strong pressure resistance, the working pressure of the water pipe system can be reached, and many brands promise to use it for 50 years.

No water leakage: PPR pipe connection uses hot melt process, hot melt connection technology is reliable, and can always be kept without water leakage.

Cheap: Ordinary PPR pipe** is basically within 10 yuan.

PPR water supply pipes.

2. Copper pipe. In many foreign high-end bathrooms, there are often the shadow of copper pipes, in addition to being expensive, there are almost no shortcomings, but due to the high cost, so the audience is relatively small, and people who have the strength to enjoy are relatively high-end. At present, the PPR copper pipe produced by Poly Pipeline combines the advantages of copper pipe and PP-R pipe, and adopts copper with a purity of more than 100, which is sterilization and antibacterial, and has good hygienic performance. The thermal conductivity is lower than that of copper pipes, and it has excellent thermal insulation performance, which is suitable for high-end residences.

3. PB pipe is recognized as a non-toxic, tasteless, durable pipeline material, and is one of the world's cutting-edge chemical materials, which has been widely used in many countries. Compared to traditional materials such as metals and ceramics, PB tubes are easier to process, can be recycled, and consume less energy throughout their life cycle. PB tube has the advantages of high surface finish and high flexibility.

Key points of purchase: brand, material, pipe diameter specifications, **.

Brands: Generally, imported brands are higher than domestic brands in terms of raw material purity, but they are not necessarily better than domestic brands in terms of key production processes and fineness. As long as it passes the inspection standards, there is no problem with the quality of domestic production, and there is no need to blindly obsess over imported brands.

Pipe diameter specifications. Generally, PP R pipes are used at home, and the normal specifications should be DE2025, 25mm outside, 20mm for good pipes, and about 21mm for the next one.

**Imported brands are generally more expensive than domestic brands:

Domestic brand: 20mm tube is about 7 10 yuan; The 25mm tube is about 15 to 20 meters.

Imported brand: 20mm tube is about 15-20 yuan, 25mm pipe is about 20-25 yuan.

If the pipe + accessories + labor costs are counted, the domestic brand ** is basically within 100 yuan m, and the imported brand is basically more than 100 yuan m.

I think it's useful, give it a thumbs up.

The water used to drink is transported through the water supply pipe, so the material of the water supply pipe is best to choose stainless steel to ensure water safety, my home is Geberit's Mapress water supply pipe, this is the material of medical grade 316 stainless steel, this stainless steel is currently the only health and safety material that can be implanted into the human body in the world, the pipe wall texture is smooth, it is not easy to form a "biofilm", the antioxidant capacity is also better than the general stainless steel pipe, and it is not easy to have bacteria for long-term use. Great recommendation!

When decorating the home, we need to install pipes, but there are different types of pipes and different materials, such as drainage pipes and water supply pipes. If you can't distinguish between them when installing, it may have the opposite effect, so what are the differences between water supply pipes and drainage pipes?

1. Different functions: If you choose a water supply pipe, it is for water supply according to its literal meaning. For household drinking water, it must meet the relevant health indicators, and this water supply pipe must be non-toxic and non-polluting, and can only be used after testing.

If it is a drainage pipe, there is no doubt that it is used for drainage, such as rainwater or community drainage, it must have a certain pressure resistance, and the buried eggplant has a certain flexibility at the same time, and the sealing is also very good, you can choose a PVC drainage pipe.

2. Different materials: The material of the water supply pipe may be some gold water pipes or plastic pipes, but the material of the drainage pipe is mainly made of high-density polyethylene and other components to make plastic pipes.

3. Characteristics: The construction of water supply pipe is more convenient, and the resistance of flowing water is relatively small, and it can also improve the water conservancy in the pipeline. The properties of the drainage pipe are more important, such as corrosion resistance, not easy to block, and it is more convenient for later maintenance.

The above is that I have introduced to you the difference between water supply pipes and drainage pipes, I believe that the big bend finger family has a certain understanding of this, I hope to help you.

First, the material is different.

Water supply pipes: Water supply pipes are made of metal pipes, composite pipes and plastic pipes.

Drainage pipe: The material of the drainage pipe is mainly a new type of seepage and drainage plastic pipe formed by adding high-density polyethylene and other additives.

Second, the characteristics are different.

Water supply pipe: The water supply pipe has the characteristics of no rust, no scaling, low fluid resistance, and can reduce the energy consumption of water supply.

Drainage pipe: Drainage pipe has the characteristics of drainage safety, corrosion resistance, etc.

Third, the use is different.

Water supply pipe: water supply pipe is suitable for domestic water supply and drainage, chemical industry, sewage, waterworks transformation, national water conservancy projects and other fields.

Drainage pipes: Drainage pipes are mainly used for drainage tasks such as rainwater, sewage, and farmland drainage and irrigation.

Encyclopedia - Drain pipes.

1. As the name suggests, it can be seen in the name that it isDifferent uses, one for water supply and one for drainage.

2. Water supply and drainage are different due to their usesThe materials are also differentThere are many kinds of materials commonly used in water supply pipes, such as PE (used in municipal engineering), PPR (the most commonly used pipes for home improvement), metal pipes, etc. Drainage pipes are mostly PVC, PP, etc., and PE can also be used for drainage, but compared with the first two materials, the cost will be more expensive.

1. Different usesPVC water supply pipe is mainly used for: Aindoor water supply and reclaimed water systems for civil and industrial buildings; b.

buried water supply system in residential areas and factories; c.Chenggeqiao City Water Supply Pipeline System; d.water treatment piping system for water treatment plants; e.

mariculture; f.Garden irrigation, well sinking and other industrial dust source processes and other industrial pipes. PVC drain pipe is mainly used for:

Building drainage, domestic sewage drainage.

2. The specifications are differentThere are many specifications and models of PVC water supply pipes in order to meet the requirements of various projects; There are relatively few specifications and models of pulse PVC drainage pipes, because the drainage system itself does not need too many specifications. Even with the same model (outer diameter), the wall thickness of the water supply and drainage pipes is often different.

3. The standards are differentUse GB for PVC drain pipes and GB for PVC water supply pipes.

4. The pressure is differentWater pipes have pressure requirements, while drain pipes usually don't need to consider pressure.
