Advantages And Disadvantages Of Copper Pipe And Stainless Steel Pipe?

Advantages and disadvantages of copper pipe and stainless steel pipe?

First, health performance
The sanitary performance of the stainless steel pipe is superior, which eliminates the problem of "red water, blue and green water, and hidden water", no odor, no scale, no harmful substances precipitation, and keeps the water quality pure and harmless to the human body. The copper pipe has the problem of excessive copper, the problem of blue and green water caused by corrosion, the corrosive bitter odor produced, and the phenomenon of scaling.
2. Service life
The aging life of stainless steel can reach more than 80 years and does not need to be replaced, while copper pipes can only be used for a maximum of 50 years.

Three, compressive strength
The compressive strength of the stainless steel pipe is greater than 520MPa, and the compressive strength of the copper pipe is less than 40% of the stainless steel pipe, and it is easier to leak by external force.
Fourth, insulation performance
The thermal conductivity of stainless steel pipe is 1/23 of the copper pipe, the thermal insulation performance of stainless steel pipe is good, especially suitable for hot water transmission, and the copper pipe needs a professional thermal insulation layer, otherwise the heat energy waste is too large.
5. Corrosion resistance
Stainless steel pipes can passivate with oxidizers, forming a protective film on the surface to effectively prevent oxidation, while copper pipes passivating capacity is small copper pipes corrosion resistance is relatively poor, the water flow is large corrosion, aging life and harmful substances precipitation, copper pipe welding on the site can not be solid solution, pickling, and passivation, it is difficult to carry out corrosion prevention of the internal welding pipe. Therefore, the welding joint is easy to corrode and easy to age.
6. Economic performance
The price of stainless steel pipe is lower than that of copper pipe, to this extent, once the stainless steel pipe is used, it is almost zero maintenance, and the service life is consistent with the service life of the building, while the copper pipe replacement, the comprehensive cost will be 2-4 times that of the stainless steel pipe
Therefore, to sum up, stainless steel water pipes due to safety and reliability, energy saving and environmental protection, good economic performance and other advantages, has been widely used in hotels, hospitals, industrial buildings, residential and national government projects, so stainless steel water pipes are known as the 21st century novel water supply pipes, worthy of the name.
