Stainless steel water pipes are very good water supply pipes. According to the actual measurement, in general, the working pressure of the stainless steel water pipe system can reach more than 2.5Mpa. Its low thermal conductivity is 1/25 of copper pipe and 1/4 of iron pipe. Its thermal insulation effect is the best among all metal pipes, and it can be used for a long time in the temperature range of -40℃~120℃. The highest temperature of domestic water is 100℃. Whether it is high temperature or low temperature, the material properties are quite stable; and it has good ductility and toughness. The high strength of stainless steel water pipes greatly reduces the possibility of water leakage affected by external forces, significantly reduces the leakage rate of water, and enables water resources to be effectively protected and utilized.
Stainless steel is a metal material. Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. It is also known as stainless acid-resistant steel. In practical applications, the steel that is resistant to weak corrosive media is often called stainless steel, and the steel that is resistant to chemical media corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel The basic alloying elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements for the structure and properties of stainless steel for various purposes. Stainless steel is easily corroded by chloride ions, because chromium, nickel, and chlorine are isotopes, and the isotopes will exchange and assimilate to form stainless steel corrosion. The corrosion resistance of chemical composition stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, with a maximum of no more than 1.2%, and the wc (carbon content) of some steels is even lower than 0.03% ( Such as 00cr12). The main alloying element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a cr (chromium) content of at least 10.5%. Stainless steel also contains ni, ti, mn, n, nb, mo, si, cu and other elements.Stainless steel is not prone to corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials in construction metal materials. Because stainless steel has good corrosion resistance, it can permanently maintain the engineering integrity of structural components. Chromium-containing stainless steel also combines mechanical strength and high elongation, and is easy to process and manufacture components to meet the needs of architects and structural designers
