Explanation of decoration construction terms (VIII)

water pipe: divided into 6 branches and 4 branches

6 branches: water pipe with an outer diameter of 25mm

4 branches: water pipe with an outer diameter of 20mm

the caliber size of the two is different, and the pipe wall thickness is also different

6 points wall thickness of cold water pipe: generally 2.3mm or 2.6mm, hot water pipe is 4.2mm

4 points wall thickness of cold water pipe: generally 2.3mm, hot water pipe is 3.4mm

the caliber size will have a certain impact on the water flow, According to the height of your floor, the direction of the waterway, and the size of the water pressure will be affected, which will directly affect the water flow. Therefore, 6 branch pipes are usually used as household water supply pipes. The difference in wall thickness has different pressure on the pipes. Generally, household water pressure < 3kg

in terms of pipe selection, cold and heat can be separated, or all can be installed with hot water pipes. After installation, the pressure test is carried out, and the pressure is 10kg for 30 minutes.

gas pipe: Teflon raw material belt, which has the characteristics of high temperature resistance, low temperature resistance, corrosion resistance, good sealing performance, etc. it is suitable for the sealing of screw threads at the valve interface of chemical pipes, water pipes, heating pipes, the sealing of corrosive fluid transmission pipe orifice and valve joint, It is easy to clean when repairing and disassembling.
