Stainless steel drain pipes and pipe fittings are healthy materials that can be implanted into the human body. Stainless steel materials can be seen in all application fields involving human health. It has been widely used. Stainless steel water pipe is an environmentally friendly material that meets health requirements, can be recycled, save water resources, reduce transportation costs, reduce heat loss, and avoid sanitary ware pollution.

Features:

1. Life
Stainless steel pipes have a long service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes is about 70 years.

2. Corrosion resistance
One of the outstanding advantages of stainless steel drainage pipes and fittings is its excellent corrosion resistance, which is superb among all kinds of pipes. Because stainless steel can passivate with oxidants, a tough and dense chromium-rich oxide protective film, Dr2O3, is formed on the surface, which effectively prevents further oxidation reactions. Other metal pipes, such as galvanized water pipes and copper pipes, have less passivation ability. This is the key reason why the corrosion resistance of galvanized pipes is far less than that of stainless steel pipes.

3. Heat resistance and heat preservation
The thermal conductivity of stainless steel pipe is 1/25 of copper pipe and 1/4 of ordinary steel pipe, which is especially suitable for hot water transportation. The stainless steel commonly used in the water industry is 304 and 316 stainless steel, which can meet most water treatment and customs conditions.

4. Strength
The tensile strength of 304 stainless steel pipe is twice that of steel pipe and 8-10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong and crashworthy. Stainless steel drain pipes and pipe fittings can withstand high water supply pressure, up to 10Mpa or more due to their excellent mechanical properties, and are more suitable for high-rise water supply.

Stainless steel water pipes reduce transportation costs
The inner wall of the stainless steel pipe is smooth, and the water resistance is small, which reduces the pressure loss and reduces the transportation cost. Due to the low thermal expansion coefficient of stainless steel, it effectively reduces the heat loss in hot water pipes. Stainless steel is a recyclable material and will not cause pollution to the environment.
