can carbon steel pipe be used for acidic water?

It is not recommended to use ordinary carbon steel pipes for the transportation of acidic water.

Ordinary carbon steel pipes may encounter corrosion problems when dealing with acidic water, because the acid can erode the inner wall of the metal, resulting in pipe damage. In order to safely transport acidic water, the following types of pipes are commonly used:

Plastic-lined steel pipe: This pipe is based on ordinary carbon steel pipe and lined with thermoplastic with excellent chemical stability, which not only takes advantage of the mechanical strength of carbon steel pipe, but also improves the corrosion resistance by lining the plastic layer.

PE pipe: Polyethylene pipe has good corrosion resistance and long service life, suitable for conveying a variety of chemicals, including acidic water.

Stainless steel pipe: Although the cost is higher, stainless steel pipe has excellent corrosion resistance and is suitable for the transportation of a variety of corrosive fluids.

In addition, when choosing the pipe for transporting acidic water, in addition to corrosion resistance, factors such as the pressure bearing capacity, temperature range and economic cost of the pipe should also be considered. For example, aluminum-plastic composite pipe is also an alternative to cast iron pipe, which combines the advantages of plastic and metal, with good corrosion resistance and high pressure resistance.

In general, ordinary carbon steel pipes are not suitable for direct use in acidic water transportation due to their relatively poor corrosion resistance. In practical applications, the appropriate pipe should be selected according to the specific nature of the conveying medium and the working environment to ensure the safe and stable operation of the system.
