Anonymous users2024-01-304. The inner diameter of the water dividing pipe is millimeters. 4 subdivisions are equal to 1 2 inches, and one inch is equal to millimeters, so the inner diameter of 4 divisions is equal to half of millimeters, that is, the inner diameter of 4 divisions is divided by 2 equals millimeters. "4 points" is the name of the diameter length of the imperial pipe, the international standard for the application of the metal pipeline water supply system is formulated by the British Empire in the heyday of history, the size of this standard is based on inches, and the colloquial language is also used more "four points", "six points", "one inch pipe" and so on.
Introduction of water pipes
Water pipes are pipes for water supply, and there are three types of them, the first type is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes, etc. The second category is plastic composite metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB pipes, PP-R pipes, etc.
When buying water pipes, be sure to choose water pipes with better corrosion resistance. Because tap water generally contains more acid and alkali substances, if the corrosion resistance of the water pipe is not good, the water pipe will be corroded by the acid and alkali substances in the water, thereby reducing the service life of the water pipe.
The color of the water pipe is different for different materials. For example, stainless steel water pipes, the color of stainless steel water pipes is generally silvery-white, if the color is a little black, it is easy to produce dirt during use. The color of the PPR water pipe with better quality is matte milky white and does not have any impurities.
