Stainless steel pipe has gradually become a new choice of water supply pipe with the characteristics of safety, sanitation, environmental protection, economy and applicability, and has become the current world trend and development direction. Stainless steel water pipe is called the real green pipe in the st century. With the gradual standardization of stainless steel pipe industry, environmental protection and sanitation for national domestic water, but also win a larger market for stainless steel pipe enterprises. Stainless steel pipe entering the construction and decoration market is an attack in the water pipe industry.

CE--“ Code for design of cold formed stainless steel structural parts & rdquo; And & ldquo; jointly published by nidi and euro inox; Structural stainless steel design manual & rdquo; The design of structural parts for buildings with long service life and good integrity has been simplified.Welcome to inquire,When the addition of chromium reaches %, the atmospheric corrosion resistance of steel increases significantly,Kansas-CityHow much is stainless steel, but when the chromium content is higher, although the corrosion resistance can still be improved, it is not obvious. The reason is that when alloying steel with chromium, you can see the natural luster of the steel surface, which makes the stainless steel have a unique surface. Moreover, if the surface layer is damaged, the steel surface will react with the atmosphere to repair itself re form this passive film and continue its protective effect.The method is that the heated tube blank is placed in a closed cylinder, and the perforated rod and rod move to extrude the part from the smaller die hole. This method can produce steel pipes with smaller diameter.Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)Kansas-City,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.
