304 stainless steel pipe features and applications

https://writersrebel.com/9186kkub3l Stainless steel is a recognized health material that can be implanted in the human body and is used in almost all areas involving human health. It has been widely used. Stainless steel plumbing is an environmentally friendly material that meets health requirements, can be 100% recycled, saves water, reduces transmission costs, reduces heat loss, avoids sanitary ware pollution and other advantages. The details are shown as follows.


1.Life span https://velvet-avocats.com/nltlql29i Stainless steel pipe has ^ long service life. Analysis of the use of stainless steel from abroad, the life of stainless steel water pipes can reach 100 years, or at least 70 years, as long as the life of the building.

Because stainless steel can be passivated with oxidizing agents, forming a layer of tough and dense chromium-rich oxide protective film Dr2O3 on the surface, effectively preventing further oxidation reactions. Other metal pipes, such as galvanized water pipes, copper pipes passivation ability is very small, which is the galvanized copper pipe corrosion resistance is far less than the key reason for stainless steel pipe. Stainless steel does not occur as uniform corrosion of carbon steel, the use of protective coating is not required; the use of stainless steel water pipe, there is no restriction on the chemical composition of the water, because stainless steel in a variety of oxygen content, temperature, PH and hardness of the water have very good corrosion resistance; stainless steel water pipe can withstand very high flow rate, 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 occur in local corrosion, 304 stainless steel can withstand the chloride content of 200ppm, 316 stainless steel can withstand the chloride content of up to 1000ppm, this conclusion is based on exposure test data and has been confirmed by the use of experience. Stainless steel tube thermal expansion coefficient and copper tube is about the same, is 1.5 times the ordinary steel pipe, compared to the stainless steel tube has the characteristics of slow thermal expansion and contraction.

Heat resistance and insulation The thermal conductivity of stainless steel pipe is 1/25 of copper pipe, is 1/4 of ordinary steel pipe, especially suitable for hot water transmission. Water industry ^ often use stainless steel is 316 and 304 stainless steel, they can meet the majority of water treatment and transmission off conditions.

The strength of the material determines whether the water pipe is strong and resistant to impact, safe and reliable. And safety and reliability is the building water ^ important requirements. In the case of impact by external forces, the possibility of leakage of stainless steel water pipes is very small. High building water supply system working pressure is generally greater than 0.6Mpa; the pipe pressure requirements are high. Thin-walled stainless steel pipe due to the excellent mechanical properties, can withstand very high water pressure, up to 10Mpa or more, especially suitable for high-rise water supply.
