904l Steel Pipe Fitting

Stainless steel is one of the metal materials for construction of very high strength material technology, 904L stainless steel elbow With good corrosion resistance, so you can make stainless steel supply water piping structural components to maintain the integrity of the engineering design, chromium-containing stainless steel with high mechanical strength and ductility, easy to process the parts to meet the needs of architects and structural designers. All metals can react with oxygen, unfortunately, ordinary carbon steel iron oxide is easy to oxidize, rust expansion, the formation of holes, but the stainless steel elbow because of the possession of an oxide film surface, does not react with oxygen. Air, steam, water and other weak corrosive media and acids, alkalis, salts and other chemical corrosive media corrosion of steel, also known as stainless corrosion acid-resistant steel, in practice, often weak corrosive media corrosion-resistant steel called stainless steel, and chemical media corrosion-resistant steel known as acid-resistant steel, due to the two in the chemical composition of the former is not resistant to corrosion of chemical media, the latter is generally with the stainless corrosion, stainless steel elbow of corrosion resistance Depends on the alloying elements contained in the steel, chromium is the basic element that makes the stainless steel to obtain corrosion resistance, the steel content reaches 1.2% or so, chromium and corrosion-resistant medium in the role of oxygen. Stainless steel elbow will not produce corrosion, pitting, rust or wear, in the stainless steel piping system, stainless steel elbow is to change the direction of the pipe. According to the angle, there are 45° and 90° and 180° in common use. In addition, according to the needs of the project, there are 60 ° and other non-normal angle elbow, elbow materials are cast iron, stainless steel, alloy steel, fired cast iron, carbon steel, non-ferrous metals and plastics, etc., and the way of connecting with the pipeline is directly welded (commonly used way) flange connection, threaded connection and insertion of the connection, etc., according to the production technology is divided into welded elbows, stamping elbows, casting elbows, etc., commonly used for connecting pipelines in the pipeline installation Used for the connection of pipe elbows, other known as 90-degree elbow, right-angle elbow, etc..
