First, the steel pipe can be used as water mains?
Steel pipe can be used as water pipe, but need to pay attention to the following issues:
1. Anti-corrosion treatment
Steel pipe is easily corroded by water, so it needs anti-corrosion treatment. Currently commonly used anti-corrosion treatment methods are hot-dip galvanizing, electro-galvanizing, spraying and so on.
2. Pipe thickening
Compared with the traditional cast iron pipe and cement pipe, the strength of steel pipe is higher, but the modulus of elasticity is smaller, that is to say, the deformation capacity of steel pipe is weaker. Therefore, when using steel pipe as water supply pipe, it is necessary to consider in pipe thickening to ensure its durability and safety.
3. Pipe connection
The connection methods of steel pipe include threaded connection, butt-welding connection, flange connection and so on. However, the sealing of threaded connections is relatively poor, and butt-welding connections and flange connections need to be carried out by professionals. Therefore, the choice of pipe connection needs careful consideration.
Second, the advantages of steel pipe as water pipe
1. High durability
Compared with the traditional cast iron pipe and cement pipe, steel pipe has higher durability and can be used for a longer time.
2. High safety
Steel pipe has good performance in pressure resistance and toughness, and steel pipe is not easy to burn, so it has higher safety.
3. Easy processing and installation
The processing and installation of steel pipe is relatively easy, which can improve the construction efficiency and control the construction cost.
Conclusion
Steel pipe can be used as water pipe, but need to pay attention to anti-corrosion treatment, pipe thickening and pipe connection and other issues. At the same time, steel pipe as water pipe has the advantages of high durability, high safety, easy processing and installation. In the specific application, it is necessary to consider various factors and choose the most suitable piping material.
