Elbow materials are cast iron, stainless steel, alloy steel, calcined cast iron, carbon steel, nonferrous metals and plastics. The connection modes with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, clamp elbow, etc. Other names: 90° elbow, right Angle bend, love bend, white steel elbow, etc.
According to the standard production can be converted into:
1. According to manufacturing standards, it can be divided into national standard, ship standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
2. The production method can be divided into pushing, pressing, forging, casting, etc.
90° stainless steel elbow is mainly used for connecting pipe fittings in pipeline installation, and is used for connecting pipe bends. Connect two pipes of the same or different nominal diameters to make a 90° turn.
Stainless steel
Usually on the basis of carbon steel increased a high proportion of Cr, Ni and other alloys, the proportion of content can reach more than 20%. Common steel types are: 304,304 L, 321,316,316 L, 1Cr18Ni9Ti,0cr18ni9. The first few steel numbers expressed by numbers are the Japanese and American steel numbers, and the last one (1Cr18Ni9Ti) is the domestic steel number.
Stainless steel characteristics: strength, toughness index is the best of all kinds of steel, its most prominent advantage is corrosion resistance, in chemical paper and other corrosive occasions must use stainless steel, of course, the cost is higher!
