What are the materials of drinking water pipes? Say what you know!

Do the math how much it will cost you to renovate your home

Water pipes are an indispensable thing for every household, and they are also necessary decoration materials for home decoration. With the improvement of living standards, many people have also paid attention to the safety of drinking water, so what material is generally better for drinking water pipes, let's take a look at the types of water pipe materials. Commonly used water pipes for home decoration can be roughly divided into galvanized pipes and UPVC pipes.

Aluminum-plastic pipes, PPR pipes, copper pipes and stainless steel pipes. 1.Galvanized pipe: Most of the old houses are galvanized pipes, and now the iron pipes used for gas and heating are also galvanized pipes, and the galvanized pipes are used as water pipes.

It not only pollutes the sanitary ware, but also is mixed with bacteria that breed on the uneven inner wall, and rust causes high heavy metal content in the water, which seriously endangers human health. Pipe: In fact, it is a kind of plastic pipe, the interface is generally bonded with glue, and the frost resistance and heat resistance of UPVC pipe are not good, so it is difficult to be used as a hot water pipe, because its strength can not be applied to the pressure requirements of water pipes, so cold water pipes are rarely used.

In most cases, PVC pipes are suitable for wire pipes and sewage pipes. 3.Aluminum-plastic pipe:

Aluminum-plastic composite pipe is a more popular pipe on the market, the current market is more famous Rifeng and Jinde, because of its light weight, durability and convenient construction, its bendability is more suitable for use in home decoration. Its main disadvantage is that when used as a hot water pipe, due to long-term thermal expansion and contraction.

It will cause the pipe wall to be misaligned and cause leakage. Pipe: As a new type of water pipe material, PPR pipe has a unique advantage, it can be used as both cold water pipe and hot water pipe, because of its non-toxic, light weight, pressure resistance, corrosion resistance, is becoming a promoted material.

5.Copper pipe: copper pipe has the advantages of corrosion resistance, sterilization, etc., is the best product in the water pipe, copper pipe interface has two kinds of ferrule and welding, ferrule and aluminum-plastic pipe are the same, there is a problem of aging and water leakage for a long time.

6.Stainless steel pipes.

It is a very expensive water pipe, which is difficult to construct and is rarely used, and its performance is similar to that of copper pipes. The above is an introduction to various materials of water pipes, I hope it will have a certain reference role for you! In addition, a friendly reminder:

If you live on a high floor, the water pressure may be small, it is recommended to change the 6 pipes, so that the water is more cool, and the 6 pipes have a thick wall and good performance. If you are satisfied, please give it a thumbs up, the pro must be my biggest motivation!

Aluminum-plastic pipes, PPR pipes, copper pipes, stainless steel water pipes, now it is PPR and stainless steel water pipes are more people buy, my home is a stainless steel pipe with gold pipes, I see my friend installed this, he said yes, I installed it, several years, the experience is still good.

Product Introduction. PP-R pipes.

PP-R pipe, also known as type III polypropylene pipe, is non-toxic, light weight, pressure resistant, corrosion-resistant, and has good impact resistance and long-term creep performance. It is mainly used in water supply piping systems and can be used in pure drinking water pipelines. PP-R pipes are divided into cold water pipes and hot water pipes.

The interface of the PPR pipe adopts hot melt technology, and the pipes are completely fused together, so once the installation pressure test is passed, there will be no aging and water leakage for a long time like the aluminum-plastic pipe, and the reliability is extremely high. PPR pipe does not scale, has good thermal insulation performance, and has a smooth pipe wall. It is becoming a kind of promotional material.

However, the high temperature resistance of PPR pipe is slightly worse, and the long-term working temperature cannot exceed 70; And it cannot be bent for construction. In terms of comprehensive performance, PPR pipe is currently the most cost-effective pipe, so it has become the preferred material for home improvement water pipe transformation. First, the main features:

1. Non-toxic, hygienic and environmentally friendly. The raw material molecule of PP-R only has carbon and hydrogen elements, and no harmful and toxic elements exist, which is not only used in cold and hot water pipelines, but also can be used in pure drinking water systems.

2. Thermal insulation and energy saving. The thermal conductivity of PP-R pipe is only 1 200 of steel pipe.

3. Good heat resistance. Vicat softening point of PP-R tube. The maximum working temperature can reach 95 °C, which can meet the requirements of the hot water system in the building water supply and drainage code.

4. Long service life. The service life of PP-R pipe can reach more than 50 years under the condition of working temperature 70 and working pressure.

5. Easy to install. PP-R pipe has good welding performance, pipes and fittings can be connected by hot melt and electric fusion, and the strength of the connection part is greater than the strength of the pipe itself. Main.

First, the main.

1. Galvanized pipe.

In order to improve the corrosion resistance of steel pipes, galvanized general steel pipes. However, after a few years of use, a large amount of rust and dirt are produced in the pipe, and the yellow water flowing out not only pollutes the sanitary ware, but also is mixed with bacteria that breed on the uneven inner wall, and the corrosion causes the heavy metal content in the water to be too high, which seriously endangers human health.

2. UPVC pipe.

UPVC pipe is a kind of plastic pipe that uses polyvinyl chloride (PVC) resin as raw material and does not contain plasticizers. With the development of chemical industry technology, it can now produce non-toxic pipes, so it has the performance of general polyvinyl chloride, and has added some excellent properties, specifically it has the advantages of corrosion resistance and good flexibility, so it is especially suitable for water supply pipe network.

3. Aluminum-plastic pipe.

The inner and outer layers of the aluminum-plastic pipe are made of special polyethylene material, which is clean, non-toxic and smooth. It can be used for more than 50 years. The middle aluminium layer is 100% insulated from gas permeation and gives the tube the advantages of both metal and plastic pipes, eliminating the disadvantages of each.

4. PPR pipe.

Also known as type three polypropylene pipes, random copolymer polypropylene pipes or PPR pipes, it has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, long service life, etc., and is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheath, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

5. No embroidered steel pipe.

Stainless steel pipe is a kind of hollow long round steel, which is mainly widely used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial transportation pipelines and mechanical structural components. In addition, it is lighter in weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of machine parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.

Summary. The material of PPR water pipe is relatively good, with hygiene, non-toxic, no rust, no scale, in line with the international standard of drinking water, high temperature resistance, high pressure resistance, heat preservation and energy saving. Low resistance, fast water flow, low noise, using German hot melt technology, easy installation, reliable connection, never leakage.

Hope mine is helpful to you.

What kind of pipes are used for drinking water pipes?

The material of PPR water pipe is relatively good, with hygiene, non-toxic, no rust, no scale, in line with the international standard of drinking water, high temperature resistance, high pressure resistance, heat preservation and energy saving.
