What material are the pipes used for domestic water supply in the factory area nowadays? ? Are galvanized steel pipes no longer needed? ? Will you be running it underground or above ground? Do you need to dig a trench? Must the burial depth be below the freezing line? ?
We still use galvanized pipes before and after the water meter.
Different projects and different owners have varying requirements; some involve overhead installations while others use underground ones, buried beneath the permafrost layer. Some buried pipes are made of stainless steel, while others use carbon steel for internal anti-corrosion protection; there are also non-metallic pipes and those with a steel framework ； Above-ground pipelines are generally made of stainless steel pipes or galvanized pipes.
Pipes under 2 inches in diameter should be galvanized pipes.
The plant supervisor can use carbon steel, which can be installed either underground or above ground. Small-diameter branches should preferably use hot-dip galvanized pipes or stainless steel pipes. For indoor water supply in buildings, non-metallic pipes, hot-dip galvanized pipes, thin-walled stainless steel pipes, or copper pipes can be used.
Depending on the project and the materials used, water supply pipes in residential applications are generally made of ball-milled cast iron pipes, galvanized pipes (with anti-corrosion coating), PE, or PPR pipes; indoors, non-metallic pipes are usually used
I see that ductile iron pipes are quite commonly used in municipal engineering. If the pipes in the factory are to be buried, ductile iron pipes can certainly be used as well; one minor issue is that connecting branch pipelines with them is not as convenient as using carbon steel pipes. Cathodic protection should be applied when carbon steel materials are used. Galvanized pipes are not suitable for burial underground; it is said that they were banned in the Shanghai area years ago. Thicker HDPE pipes can also be used.
The main pipes are made of carbon steel, the branch pipes are galvanized pipes, and those with a diameter smaller than DN20 are made of PPR pipes. Install it as overhead as possible
20# carbon steel pipes are used for buried water pipes, while galvanized steel pipes are used above ground
There are many price comparisons for ordinary galvanized products in the factory area
