These days, a variety of water pipes and fittings are widely used in buildings and urban facilities, which vary depending on the type of application and location used.
You can find galvanized pipe in the form of galvanized steel pipe or galvanized iron pipe in the market.These two types of water pipes , of course , are known as white iron tubes .of course there is little difference between the two pipes And we can only say that galvanized steel pipe is lighter and more shiny than the iron model.
the most important application of galvanized steel pipes is ventilation . However, it can also be used to drain domestic sanitation. This type of water pipe is less resistant to acid than the iron model In fact, any acid that damages the cast iron is harmful to the galvanized steel pipe.
Work with galvanized iron tubes requires little accuracy and skill Because when making this pipe, galvanized coating or the same as zinc alloy is used If welding is used for its connections, the heat caused by its smoke will damage the respiratory system. The use of this pipe is the same as steel pipe.
Cast iron pipe is also one of the types of water pipes which is made of cast iron. Cast iron pipes vary depending on the type of application, the amount of alloy used in it, the shape and length of the pipe and the type of fittings, and are usually one of the types of utility pipes used in sewage piping.
1.Compared to galvanized water pipes, the possibility of wear in cast iron pipes is less.
2.Cast iron probe has good strength and resistance to pressures on the outer wall.
3.One of the best advantages of cast iron pipe is that it can be easily clogged by an air compressor, which is easily possible.
4.Cast iron pipe prices lower than iron pipe
1.cast iron pipe installation is time consuming than iron pipe.
2.Cast iron pipes are easily corroded by water chemicals and have no resistance.
3.The weight of cast iron pipe is very high and this has made it difficult to install and transport.
Plastic tubes are more applicable to plumbing and installations . As you know, the use of metal pipes in building installations leads to many problems such as decay, sediment and other harmful damages. Therefore, the experts decided to test another model of different types of water pipes by testing different alloys, in which the plastic model was selected as the best model. however , problems such as oxygen diffusion , high temperature tolerance , high expansion coefficient and … . Therefore, a group of scientists cleverly combined the best water pipe for a building under the title of "five-layer pipe". It consists of an aluminum tube , two polymer layers , and two special glue layers . Its superior features include its resistance to corrosion, rust, sediment and decay, as well as its ability to withstand constant heat at high pressures and its impermeability.
1.five - layer pipe does not ring anywhere , precipitate sediment And it never rots.
2.The light weight of the five-layer pipe makes it easy to transport.
3.the five - layer pipe bends easily and this pipes flexible and self - forming.
4.oxygen doesn 't penetrate the this tube As a result, you will never see the water change color.
5.The coefficient of expansion of a five-layer pipe is very small.
6.It is resistant to pressure of this pipe.
7.Due to the smoothness of the surface inside the pipe, the possibility of pressure drop is very small.
8.It can withstand continuous heat.
9.It can be easily used in built-in plumbing and also has a beautiful appearance in surface installation.
Well, as we have seen so far, the best water pipe for the building so far has been the five-layer pipe model Which is located under the plastic pipe assembly , Now let's get acquainted with different types of plastic pipes in water and sewage facilities :
1.PVC plastic pipe
2.PE plastic pipe
3.ABS plastic pipe
4.PP plastic pipe
5.CPVC plastic pipe
1.As compared to other types of water pipes , the PVC tube has simpler connections And its parts are installed faster than other types of water pipes.
2.PVC pipe is very light weight And you can easily use it between false ceilings and any other place that has difficulty accessing.
3.The outer diameter of the PVC tube was less than the size of the tubes And it is easily embedded inside the wall.
4.You will not need to paint when installing PVC pipe surface.
1.one of the disadvantages of the pvc pipe is losing its strength and its form against heat In addition, dry PVC pipe is very brittle against cold.
2.To open the PVC pipe duct, an opening pipe spring should be used because the power of its double skin is low.
3.The resistance of PVC pipe against external forces is low.
1.The first type of polyethylene pipes have low strength resistance along with density And their flexibility is also good .
2.The second type of polyethylene pipes have a medium density And of course , they 're a bit harder than the first It also has higher strength and higher expandability than the first type.
3.But the third type of polyethylene tube is much heavier than the other two samples . has more density And of course they have unique physical properties in terms of strength, expansion, stiffness, roughness and… . Of course, their wide application can be seen in gas supply and water supply.
Keep in mind that to choose the best type of water pipe, you must consider the different characteristics of the pipe, such as fittings, resistance, scale and other factors.
