The first goal of the correct implementation of urban and domestic sewage piping is to remove the polluted sewage from residential areas and transfer it to the settlement house. If the installation of the sewer pipe is not done according to its principles, it will cause wear and tear and shorten the useful life of the building's sewage transfer system; For this reason, it is one of the most prominent stages of construction and even reconstruction of the building.
The benefits of proper implementation of sewage piping
1- Accurate estimation of the amount of materials and materials required for the implementation of the building's sewage piping project, which prevents the purchase of oversize pipes, fittings and other items, which reduces waste and minimizes the cost of implementation. 2- Work mistakes and rework due to the lack of expertise of the sewage system implementation agent are prevented. 3- One of the important parameters in this field is the standard and first-class equipment of sanitary facilities, which will increase the lifespan of the sewage system.
Types of sewage pipes
In the course of time, pipes of different types and quality have been used for sewage piping. In this section, we explain the most important types. Cast iron pipe: is one of the oldest sewer pipes, which has become obsolete due to its heavy weight, high cost, difficult and time-consuming implementation. Plica pipe : This pipe is almost the cheapest type of pipe for sewage, there is no prohibition to use it, but it is not recommended due to the use of Plica granule pipe by some people, which is a kind of recycled and low quality pipe. Galvanized pipe: This pipe is used for sanitation and is resistant to corrosion and rust due to having an insulating layer. Polyethylene pipe: This type of pipe is produced with three types of materials: PE63, PE80 and PE100. PE63 is almost obsolete and standard 4 bar and 6 bar polyethylene pipes are used for sewage piping. Pushfit pipe: The best pipe for sewage piping is Pushfit, which is produced in two models, normal and silent. In the silent model, which has a higher price, when the sewage passes, its sound is not heard in the interior of the building. The connection of push fit pipes is male and female and is sealed inside by a rubber gasket.
Types of sewage piping methods
The method of plumbing is related to the way it is done, and the material and type of pipe can be Plica, Polyethylene or Push Fit.
Sewer piping by tunnel method: Sewer pipes in this method pass through the excavated tunnel. Open sewage piping: In this method, which has been done in the past, the pipes are placed on the floor of the building and covered with materials, hence it is called the traditional method or sleeping floor. under-ceiling sewage piping: in under-ceiling piping, instead of placing the sewer pipes under the floor of the building, they are placed on the roof. Of course, in some projects, a combination of open and under roof methods is done.
