Comparison Of Copper Pipe And Stainless Steel Pipe

Many five-star hotel standards require copper pipes to be used in water supply systems. However, due to cost and market reasons, more and more hotels now accept stainless steel pipes. Today, we mainly compare the physical properties of copper pipes and stainless steel pipes.

Comparison of tensile strength:

Take the commonly used 304 thin-walled stainless steel pipe as an example, its tensile strength is 530-750Mpa, which is twice that of galvanized pipe and three times that of copper pipe. Therefore, the thin-walled stainless steel tube can be thinner than the copper tube (0.6MM), which is in line with the national industrial policy of saving materials, has the guarantee of strength, and can achieve the purpose of reducing the load-bearing of buildings.

Comparison of thermal conductivity:

The thermal conductivity of the thin-walled stainless steel pipe is 15 W/m°C (100°C), which is 1/4 of the carbon steel pipe and 1/23 of the copper pipe. Due to their good thermal insulation performance, thin-walled stainless steel pipes are especially suitable for hot water transportation. Whether it is the thickness of the thermal insulation layer, or the construction and maintenance costs of thermal insulation structures, thin-walled stainless steel pipes have a better economy.

Comparison of thermal expansion coefficients:

The average thermal expansion coefficient of the thin-walled stainless steel pipe is 0.017mm/(m°C), which is close to the copper pipe. Metal pipes should be used for hot water transportation.
