The tensile strength of 304 stainless steel water pipe is 2 times that of steel pipe, 3-4 times that of copper pipe, and 8-10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong, collision-resistant, safe and reliable. Safety and reliability is an important requirement for building water supply.
Comparing thermal expansion performance and thermal insulation performance:
The thermal expansion coefficient of stainless steel pipe is similar to that of copper pipe, which is 1.5 times that of ordinary steel pipe. In contrast, stainless steel pipes have the characteristics of slow thermal expansion and cold contraction. Excessive expansion coefficient of plastic pipes is its Achilles heel and is not suitable for hot water pipes. In the case of changes in ambient temperature, plastic pipes are prone to safety risks such as leakage, especially in concealed works. The composite pipe has the problem that the expansion coefficients of the two materials are inconsistent, and the connection of the two materials is easy to crack, causing the water pipe to burst.
Corrosion resistance comparison:
One of the advantages of stainless steel pipe is its excellent corrosion resistance, which is the best among the five types of pipes. Due to the passivation of stainless steel with oxidants, a tough and dense chromium-rich oxide protective film Cr2O3 is formed on the surface, which effectively prevents further oxidation reactions.
