The pipes used for building water piping are as follows:
Galvanized
These pipes are divided into two categories: galvanized steel pipe and iron galvanized pipe. In the market, these pipes are known as white iron pipes. Usually, there is no difference between these two pipes except that the galvanized steel pipe is lighter than the iron one. Galvanized pipes are mostly used in old buildings. This pipe can be used in situations where it is possible to repair the pipe after some time.
Cast iron
The material of these pipes is cast iron and they differ according to the application, the amount of alloy, the shape and length of the pipe, and the type of connections. This type of pipe is mostly used for sewage and gas piping. These pipes are resistant to pressure and wear less than metal pipes. In addition, the price of these pipes is lower than metal pipes.
◾️ Steel pipe
are made of stainless steel. These pipes are used in areas where corrosion and decay are more likely, such as the bathroom.
◾️ Brass pipes
These pipes are made of a combination of brass and copper. The resistance of these pipes against rust is high.
◾️ Copper pipes
These pipes are among the most resistant pipes against corrosion and damage. These pipes are usually welded together, so additional fittings are needed to connect these pipes together.
◾️ Five -layer pipes
In building plumbing, the issue of corrosion and sediment formation in metal pipes causes a lot of damage and problems. To overcome this problem, many ways have been proposed, such as using different alloys or coating the pipes. Five-layer pipes can solve this problem well. These pipes do not rust and bend easily.
◾️ Plastic pipes
Polymeric pipes made of PVC, PE, PEX and ABS are widely used in construction piping. PVC pipes are mostly used for water and drainage piping. These tubes are not flexible. Thermoplastic or PEX pipes are widely used for building plumbing. These pipes are flexible and easy to bend.
