Water treatment engineering is a very important part of urban development and infrastructure construction. The selection of steel pipe is a crucial part of the water treatment engineering. In order to ensure the quality of the water treatment engineering and ensure the safety of the engineering and the local people, it is necessary to pay attention to the following issues when selecting steel pipes:

1. Steel pipe material: Steel pipe materials can be divided into carbon steel, alloy steel and stainless steel. Carbon steel has the advantages of low price and good mechanical properties, but it is easy to rust and corrode, and can not be used for long-term; alloyed steel has better mechanical properties and corrosion resistance. However, the price is higher than that of carbon steel; stainless steel has better corrosion resistance and durability, but the price is relatively high. According to the requirements of the engineering, the appropriate steel pipe material should be selected.

2. Steel pipe wall thickness: The wall thickness of the steel pipe should meet the requirements of the engineering design. Generally speaking, the wall thickness of the steel pipe is related to the pressure and temperature of the pipeline. The higher the pressure and temperature of the pipeline, the thicker the wall thickness of the steel pipe will be.

3. Steel pipe bending degree: The bending degree of the steel pipe refers to the curvature of the bend. The larger the bending degree, the more curved the steel pipe will be, and the greater the difficulty of pipe installation. Therefore, the bending degree of the steel pipe should be selected according to the requirements of the engineering design.

4. Steel pipe surface treatment: The surface of the steel pipe should be treated to reduce the corrosion rate of the steel pipe. Generally, it is divided into pickling and rust removal, galvanized and epoxy coating. According to the actual engineering conditions, the appropriate surface treatment should be selected.

In conclusion, when selecting steel pipes for water treatment engineering, we should consider the material, wall thickness, bending degree and surface treatment of the steel pipe according to the actual engineering requirements. Only by selecting the appropriate steel pipe can we meet the requirements of the engineering and ensure the safety of the engineering and the people.
