It is an important decision to select suitable drainage pipes, because the selection of pipes is closely related to the quality and reliability of the entire drainage system. Some general principles and basis for selecting drainage pipes will be introduced below.

First, pipes should be selected according to the specific requirements of the drainage system. Drainage system includes indoor drainage system and outdoor drainage system. Therefore, we need to select appropriate pipes according to the specific situation.

For the indoor drainage system, the commonly used pipes are PVC pipes, PVC-U pipes, PP pipes and PE pipes. These pipes have the characteristics of environmental protection, corrosion resistance and high temperature resistance, and are suitable for the drainage system of indoor families, businesses and public buildings. Among them, plastic pipes are the most commonly used. They have the advantages of low cost, convenient installation, long service life, etc.

For outdoor drainage system, the requirements for pipes are higher, and the factors such as its compression resistance, toughness and weather resistance need to be considered. Common pipes include cast iron pipes, ceramic pipes, concrete pipes and reinforced concrete pipes. These pipes have good strength and corrosion resistance, and are suitable for municipal engineering, industrial drainage, agricultural drainage and other fields. At the same time, the pipe diameter and wall thickness of the pipe should also be considered to meet the needs of the drainage system.

Secondly, the economy and cost performance of pipes should be considered. When selecting pipes, not only the price of the pipe itself, but also its service life and maintenance cost should be considered. Generally speaking, although the price of plastic pipes is relatively low, their service life is short and they may need to be repaired and replaced more frequently. In contrast, the price of metal pipes is relatively high, but their service life is long, and the frequency of maintenance and replacement is low.

In addition, the construction and installation requirements of pipes shall also be considered. Different pipes have different construction and installation requirements, such as connection mode, sealing performance, etc. When selecting pipes, construction convenience and installation effect shall be taken into consideration according to the specific situation, so as to select appropriate pipes.

Finally, the environmental protection performance of pipes should be considered. In modern society, environmental protection is an important issue, so the impact on the environment should be considered when selecting pipes for drainage. Some plastic pipes will produce harmful substances during production and use, which will pollute the environment. Therefore, when selecting pipes, non-toxic and environmentally friendly materials should be selected as far as possible to reduce environmental pollution.

In a word, many factors need to be considered when selecting suitable drainage pipes, such as pipe characteristics, economy, construction requirements and environmental protection performance. Only by comprehensively considering these factors can we choose the pipes that meet our own needs, so as to ensure the quality and reliability of the drainage system. Hainan Municipal Pipeline
