Drainage Pipeline

Keywords:Drainage Pipeline, Sewage Pipeline
Drainage pipeline refers to collection systems that discharge sewage, wastewater and stormwater drainage pipes and ancillary facilities composed. Including dry pipe, manifolds and pipes leading to the treatment plant, or any other place, whether on the streets built, as long as they play the role of drainage pipes, drainage channels should be as statistics. Length of sewer drain by all, trunks, branch pipes and inspection wells, connection length and calculate well as import and export, excluding rainwater drains mouth to the connecting pipe between the pipe and open channel into the household. When calculating a single tube should be calculated, that is, in the same street where two or more side by side drains, drainage channels and should be the length of each calculation.

Pipe Type 
Galvanized iron pipe is currently the largest amount of a material to use, because galvanized iron pipe corrosion caused by high levels of heavy metals in water, affect human health, the government sector in many countries and regions have begun to explicitly prohibit the use of galvanized iron pipes. At present, China is gradually phased out this type of pipe. 

Brass is a more traditional but the price is more expensive pipe material, durable and construction more convenient. In many imported sanitary products, brass is the first choice. Price is the most important reason affecting their usage, in addition to copper corrosion is on the one hand factor. 

Stainless steel tube is a more durable piping material. But its high price, and the construction process is relatively high, especially the strength of the material is hard, very difficult scene processing. Therefore, the probability of the renovation project was selected low. 

Plastic composite pipe is a pipe more popular in the market because of its light weight, durable and easy construction, which can be more suitable for use in bending home improvement. Its main drawback is used for hot water pipes in use, due to thermal expansion and contraction will cause long-term dislocation wall resulting in leakage.
