德国STC

Home decoration, for many people who have experienced and are experiencing, is more or less accompanied by a nervous and nervous process. Looking for design, focusing on construction, buying building materials, picking furniture... A series of complex links, a little carelessness, may destroy the new house. 德国STC Xiaobian summarized the ten problems that consumers often face when purchasing PPR pipes in daily sales experience, hoping to help you avoid the open and hidden arrows of home decoration.

1. The water pipe is buried under the wall and can't be seen underground. Is it necessary to use the best water pipe?

Water pipes are the top priority of decoration quality assurance. Visible materials are easy to replace, quality problems are easy to find, and will not cause great losses. The water pipes are buried in the wall or underground. Problems are not easy to find and very difficult to repair. Once problems occur, the impact surface and loss will be great. Therefore, for long-term safety, high-quality water pipes should be selected.

2. Which is the higher cost performance of 德国STC compared with domestic products?

The quality of PPR pipe is ultimately reflected in safety and service life. Imported PPR materials are much better than domestic materials in terms of anti aging, pressure resistance, environmental protection and other indicators, and the service life is much larger than domestic products. Therefore, the price of German STC is slightly more expensive than other water pipes, but from a few decades to a long term, the comprehensive cost performance is higher.

3. Is 德国STC really imported from Germany?

The packaging of each water pipe and each accessory of STC in Germany has a clear origin mark.

4. The outdoor water pipes are very ordinary water pipes. No matter how good they are at home, they are also a waste?

The outdoor water pipes are managed by the municipal or property management department, and the relevant units shall be responsible for any leakage and damage; Indoor water pipe problems can only be borne by themselves. The outdoor water pipes are exposed pipes, so it is relatively easy to repair and find, while the indoor water pipes are concealed, so it is troublesome to repair problems. So we should use good water pipes at home.

5. Which is higher grade, more durable and more economical, copper pipe, stainless steel pipe and PPR pipe?

First of all, copper and stainless steel as metal pipes, their raw materials are non renewable resources, the price will be very high and environmentally friendly. In addition, the connection mode of metal pipeline (clamping or welding) has high technical requirements for installation, and there is a certain hidden danger of water leakage. Thirdly, copper pipes have high requirements for water quality. If the pH of water does not meet the standard, chemical reaction will occur, and copper ions will be released into the water, which is harmful to health. Therefore, the use of copper pipes is prohibited by law in some areas of Germany. The thermal insulation performance of PPR pipe is better than that of metal pipe, and there is no need for thermal insulation layer; The price of raw materials is relatively low; The installation is simple. As long as the installation and pressure test are qualified, there will be no problems and hidden dangers in future use. The PPR raw materials and finished products of STC in Germany have passed a number of international tests and will not have any adverse impact on health.

Therefore, PPR pipe is the mainstream product in the future, which is most suitable for home decoration, regardless of price, durability, installation and use.

6. Can the cold water pipe of the imported PPR pipe be connected with hot water?

Of course, the cold water pipe can take hot water, but the question is how long can the cold water pipe take hot water? You should know that the higher the temperature, the greater the pressure, and the shorter the service life of the pipeline. Take the imported PPR pipeline of STC in Germany as an example, 25 × 2.3 the pipeline (i.e. cold water pipe) can be used for 50 years under 70 ℃ and 4kg pressure. twenty-five × 4.2 the pipeline (i.e. hot water pipe) can be used for at least 50 years under 70 ℃ and 8kg pressure. Therefore, although the cold water pipe can take hot water, it is safer to use the hot water pipe as much as possible.

7. How to distinguish the advantages and disadvantages of imported PPR pipeline

1、 To "see"

High quality imported PPR water pipe: because its material is evenly mixed and has good temperature and pressure resistance, it has soft and bright color and a sense of oil quality;

Poor PPR water pipe: due to the incorporation of more impurities, the color is dark.

2、 To "touch"

The internal and external walls of high-quality imported PPR water pipes are smooth without concave convex cracks. The inner wall of inferior PPR water pipe is rough and concave convex.

3、 To "weigh"

As the high-quality imported PPR metal pipe fittings use brass as raw material, the amount is sufficient and the weight is heavy. Nickel plated copper parts are selected for inferior PPR pipe fittings, with secondary materials and light weight.

4、 To "burn"

High quality imported PPR water pipes are very fine in material selection. Generally, they use 100% of the food grade raw materials of world-famous chemical companies. They have excellent thermal stability and high purity, and will not produce pungent smell after combustion. Poor PPR water pipes: due to the mixing of poor plastic and other impurities, there will be peculiar smell and residue during combustion. It is suggested that when purchasing, you can cut a sheet from the PPR water pipe and burn it with a lighter to identify it.
