Sewer pipe materials are the following:

First: the galvanized iron pipes
Galvanized iron pipe is currently the largest use of a material. Because of galvanized iron pipe corrosion caused by heavy metal content in the water is too high, the impact on 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.

Second: Brass
Brass is a more traditional but more expensive pipe material, durable construction and more convenient. In many imported sanitary products, the brass is preferred. The price is the most important reason affecting their usage, while copper corrosion factor is on the one hand.

Third: stainless steel pipe
Stainless steel tube is a more durable piping material. But its price is higher, and the construction process is relatively high, especially in the material strength is hard, on-site processing is very difficult, so the renovation with less.

Fourth: plastic composite pipe

Plastic composite pipe is a pipe on the market are more popular because of its light weight, durability and ease of construction, which may be more suitable for use in the bending of home improvement. Its main disadvantage is that when used as hot water pipes, the thermal expansion and contraction can cause long wall dislocation resulting leakage.

Fifth: stainless steel clad pipe
Stainless steel composite pipe and plastic composite pipe in the structure similar to a certain extent, the performance is relatively close. Also, due to the strength of the steel issue, still difficult construction.

Sixth: PVC pipe
PVC (polyvinyl chloride) plastic pipe is a modern synthetic material pipe. In general, because of its strength is far from meeting the requirements of pipes under pressure, so rarely used in water pipes. In most cases, PVC pipe for wire and pipes and sewage pipes.
