Steel: They are one of the most widely used pipes in the industry and after their production To stay safe from rust, they are placed in zinc solution. Steel pipes are used to transport liquids and gas, but acidic and alkaline materials provide conditions for rusting. These types of pipes are light in weight and last approximately 25 to 50 years.

Copper: the most widely used pipe for water supply and air conditioning are copper pipes, but they have a high price compared to other pipes, the diameter of these pipes is small, and due to their resistance to rust, their life is long, they also show resistance to heat and high temperature, and they are used to transport water Hot and steam are good options and have good plasticity.

Plastic: Plastic pipes are light in weight, which makes them very easy to work with, and they also have the ability to transport liquids and gases, and alkaline and acidic materials (because they are resistant to rust). ) but due to their high expansion coefficient, they do not have the ability to transport and transport hot materials, and due to their smooth inner surface, they get less sediment. In addition, plastic pipes are resistant to electric currents and are flammable in combustion conditions. span>

cast iron: resistance in Against corrosion and useful life (100 years), they have made the type of pipes used in water and sewage systems. Cast iron pipes have a diameter of 5 to 120 cm, and they are also able to withstand variable pressures, and their prices are reasonable.

Galvanized: Material This type of exposed white iron pipe has a diameter of 12 mm to 15 cm and a length of 6 meters. In order for these pipes to be galvanized, they must be placed in a zinc solution after production. This type of pipe is used to transport liquids and gas. They are severely affected by the destructive effects of acidic and alkaline substances. These pipes are produced in two types, light and medium, which are easy to work with and have a useful life of almost 10 years, and their prices are low.

Wrought iron: these pipes are very similar to galvanized pipes and only The difference between them and galvanized pipes is that they are also made without seams, their diameter is from 12 mm to 15 cm, and due to their lightness, it is not difficult to work with them. Wrought iron pipes are generally decorative, but they are also used to transport liquids and gas. They take
