Stainless steel material is a recognized health material that can be implanted into the human body, almost used in all fields involving human health.  It has been widely used.  
Stainless steel conduit is the material of environmental protection, satisfy healthy requirement, can be recycled 100%, save water resource, reduce transport cost, reduce heat loss, avoid clean to provide the advantage such as pollution. Details are as follows

1. Stainless steel has the longest service life. Use condition analysis from abroad stainless steel, the service life of stainless steel conduit can amount to 100 years, also have 70 years at least, as long as the life of the building.
1.Corrosion resistance One of the most outstanding advantages of stainless steel is its excellent corrosion resistance, which is the best among all kinds of pipes.  Because stainless steel can be passivated with oxidants, forming a tough and dense layer of rich oxide protective film Dr2O3 on the surface, effectively prevent further oxidation reaction.  And other metal pipe material, like galvanized conduit, copper tube passivization ability is very small, which is the key reason that the corrosion resistance of the copper tube of galvanized pipe is far less than that of stainless steel pipe (tube)material.  Stainless steel will not be as uniform as carbon steel corrosion, use without protective coating; The use of stainless steel water pipe, there is no limit to the chemical composition of water, because stainless steel in all kinds of oxygen content, temperature, PH and hardness of water are very good corrosion resistance; Stainless steel water pipes can withstand very high flow rates, even if the flow rate is greater than 40 m/s, still maintain a very low corrosion rate, not more than 0.003 mm/year, especially suitable for high-rise water supply. Stainless steel generally does not have local corrosion, stainless steel can withstand chloride content up to 200ppm, 316 stainless steel can withstand chloride content up to 1000ppm, this conclusion is based on exposure data and has been confirmed by experience. The coefficient of thermal expansion of stainless steel tube and copper tube is about 1.5 times that of ordinary steel tube. Compared with stainless steel tube, it has the characteristics of slow thermal expansion and cold contraction.
2.The thermal conductivity of heat resistant and heat preservation stainless steel is 1/25 of that of copper pipe and 1/4 of that of ordinary steel pipe, especially suitable for hot water transportation.  Stainless steel 316 and stainless steel are the most commonly used stainless steel in the water industry, which can meet most water treatment and transport conditions.  
3.The tensile strength of stainless steel is 2 times that of steel pipe, 8~10 times that of plastic pipe.  The intensity of material decided conduit whether firm be able to withstand collision, safe and reliable.  Safety and reliability is the most important requirement of construction water supply.  Below the circumstance that gets external force bump, the possibility that stainless steel conduit leaks is minimal.  The working pressure of high-rise water supply system is generally greater than 0.6mpa;  High pressure requirements for pipe.  Thin wall stainless steel pipe due to excellent mechanical properties, can withstand high water pressure, up to 10Mpa, especially suitable for high-rise water supply.
