1, 48 galvanized pipe weight 9-10 fixed length galvanized pipe every 6 meters. The 4 one is 7.92 kilograms per kilogram, about 126 tons per ton. The 6 one is 10.2 kilograms per kilogram, about 97 to 98 tons per ton. The 1 inch tube is 15.1 kilograms per ton, about 66 tons per ton. The 1.5 inch tube is 23.87 kilograms per ton, about 42 tons per ton. The 2 inch tube is 30.33 kilograms per ton, about 33 tons per ton. Reference material: GB GB/T30916 sub galvanized pipe is 20, calculated by ton. According to the above conversion, it should be less than 60 yuan.
The price of 2100 galvanized steel pipes is about 40 yuan /m, and the installation cost is about 20-30 yuan /m. They have good strength, stiffness and impact resistance, have a certain degree of resistance to temperature and pressure, moderate price and price source network. For reference only.
As a water pipe, after several years of use, a large number of rust and dirt are produced in the pipe. The yellow water not only pollutes the sanitary ware, but also is mixed with the bacteria that grow on the unsmooth inner wall.
