Pipeline laying priority is the most important concealed project, pipeline maintenance is also troublesome, if the choice is less than the quality of pipeline fittings is good, there will probably be a lot of trouble later, so you can avoid trouble at home, the next generation is just Jinan pipeline dredging introduced some common sense of the choice of family pipeline fittings for you.
1. The price of PPR pipes, pipe steel models, copper pipes and steel model pipes is relatively high. The price of PPR pipes and fittings is higher than that of steel model pipes and fittings. Copper pipes are the most expensive. The price of PPR pipes is about four times as high as that of steel model pipes.
Home decoration pipes laid should be avoided as far as possible from the ground, preferably from the top or wall straight line, the content of water pipe materials may slightly increase, but it will help the future work of water pipe maintenance smoothly.
3. The wall thickness of hot water pipes is different from that of cold water pipes. Cold water pipes can not be used as hot water pipes. The simple way to distinguish hot water pipes from cold water pipes is to mark hot water pipes with red lines.
4. The standard length of PPR pipe is every 4 meters. When purchasing, you should ask clearly whether the merchant says the price of each pipe or the price of each meter. When sending the pipe, you should remember to check whether the length of the pipe meets the requirements.
5. Family decoration should pay attention to pipe diameter and wall thickness. The general manager should use 6% pipe material, 4% pipe material can be selected to ensure water consumption, and 6% pipe material can also be used.
6. When purchasing pipes for home decoration, attention should be paid to whether the pipe diameter is symmetrical. The asymmetrical pipe diameter will affect the connection of the two interfaces.
7. The Code for Quality of Home Decoration Engineering of the Association of Building and Decoration Industry stipulates the time and pressure of pressure testing: the new water supply pipeline must be tested according to the regulations.
8. Testing pressure of metal pipe and its composite pipe is 0.6 mpa, keeping pressure for 10 minutes. The pressure drop in the pipeline is not more than 0.02 mpa, no leakage; the test pressure of the plastic pipe is 0.8 mpa, and the pressure is stable for 20 minutes. The pressure drop in the pipeline does not exceed 0.05 mpa, and there is no leakage in the pipeline.
Nowadays, the market is full of pipes, consumers are often easily confused in the process of choosing domestic pipe fittings. I hope that Jinan pipeline dredging can help you to choose high-quality pipe fittings. For more information, please visit the website: http://www.lrsuo.com.
