Galvanized pipe
Galvanized pipes are divided into two types of steel and iron pipes. They are not resistant to acidic substances. They are made of mild steel and are often used as sewer pipes for various places in the structure. In contrast, galvanized iron pipes are light in weight and gray in color. Galvanized pipes have high pressure resistance, but they suffer from corrosion and sedimentation, so they are rarely used for piping in today's buildings. These pipes are dangerous to human health due to the thick smoke that is created during welding. throws and pollutes the environment, they cannot be connected to each other through welding.
Polypropylene pipe
The weight of these pipes is very light. It is resistant to green pipe, which has made its use popular in construction. These pipes have very high strength and are not damaged by acidic and mineral substances. In addition, the resistance of these pipes has made them resistant to impact and made them an ideal pipe in the construction industry. It should be noted that polypropylene pipe is also known as single-layer pipe and PP pipe in the market.
Cast iron pipe
These pipes are made of cast iron and depending on the place of use, they are made in shapes, dimensions, connections and types of alloys. The cast iron pipe has the necessary resistance against the pressures that are applied to it and is less eroded than the iron pipes. This pipe is opened by the air compression device and its clogging is removed. The biggest disadvantage of these pipes is their corrosion due to the presence of chemicals in the sewage, which is inevitable.
