In the piping system, the piping is to change the direction of the elbow pipe. Divided by the angle of the alloy tube, there are 45 ° and 90 ° 180 ° three most commonly used, according to project needs in addition also includes other non-normal 60 ° angle bend. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics. Way connected with the pipe are: direct welding (the most common way) flange connection, hot melt connection, fused connection, threaded connections and socket type connections. According to the production process can be divided into: welding elbow, pressing elbow, push the system elbow, casting elbow, butt elbow. Other names: 90 degree elbow, right angle bend, bend, etc. love. Austenitic stainless steel elbow Material Classification editor austenite stainless steel substrate with a face-centered cubic structure (γ-phase) based, non-magnetic pipe fittings, mainly through cold working to strengthen it (and may cause certain magnetic) stainless steel. Austenitic - ferritic (duplex) stainless steel substrate of both austenitic and ferritic two-phase structure (the content of which phase is generally less than 15%), with a magnetic steel pipe fittings, strengthening effect can be achieved by cold stainless steel. Ferritic stainless steel substrate to ferrite body-centered cubic crystal structure (α-phase) based, magnetic, generally can not be hardened by heat treatment, but it may be slightly enhanced cold working stainless steel. Martensitic stainless steel matrix to martensite, magnetic, mechanical properties can be adjusted by means of heat treatment of stainless steel. Precipitation hardening stainless austenitic or martensitic matrix organization, and through precipitation hardening (also known as age-hardening) treatment it hard (strong) of stainless steel. Stainless steel 1Cr18Ni9Ti 0Cr18Ni9 00Cr19Ni10 0Cr17Ni12Mo2Ti 00Cr17Ni14Mo2 304 304L 316 316L etc. 3, stainless steel elbow with a certain degree of corrosion (oxidizing acids, organic acids, cavitation), heat and wear resistance. Typically used in power plants, chemical, oil and other equipment and materials. Welded stainless steel elbow poor, should pay attention to the welding process, heat treatment conditions and the appropriate choice of welding.
