Series & mdash; Martensitic precipitation hardening stainless steel.The content of chromium, molybdenum and nitrogen in local corrosion-resistant duplex stainless steel makes it have strong ability to spot corrosion and interstitial corrosion in oxidizing and acidic solutions.The domestic prospect is promising, and there is a large demand for building water supply pipes. According to the 'Ninth Five Year Plan' of construction and the outline of long-term objectives in , the demand for each pipe is ~ km from to , including km of cold and hot water pipes in residential construction areas. Some people believe that the development of stainless steel water pipes is of great significance to improve the grade of modern urban buildings.market price,Decorative stainless steel pipe: usually the outer wall is relatively bright, so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe, the price also varies greatly. The general production process of decorative stainless steel pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product pipe stainless steel product pipe: generally, the surface of stainless steel product pipe is also a bright surface, and a small number of pipes with acid pickling industrial surface. As mentioned above, stainless steel product pipe belongs to the purpose of stainless steel products, because the outer diameter size, mechanical properties, acid, alkali and corrosion resistance of stainless steel pipe are relatively good, Therefore, stainless steel pipes are generally used as anti-corrosion materials or hardware products in large-scale production enterprises. The production process of stainless steel pipes is one-time forming, and nitrogen protection is also added during welding.With the implementation of China's reform and opening up, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity.
