In the pipeline system, stainless steel elbow is to change the direction of the line pipe fittings. Points according to the Angle 45 ° and 90 °、 180 ° that three most commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend.
Elbow materials, stainless steel, alloy steel, cast iron can be calcined cast iron, carbon steel, nonferrous metal and plastic, etc. With the pipe connection ways: direct welding (way) of the most commonly used flange connection, hot melt connection, fused connection, threaded connection and socket type connector, etc. According to the production process can be divided into: welding bend, stamping elbow, pushing system bend, casting bend, etc. Other names: 90 degrees bend, right-angle bend, such as love and curved.
Stainless steel elbow from carbon steel elbow is the main material is different, its chemical composition can keep the elbow surface for a long time will not rust, does not corrode. According to the standard production can be turned into: stainless steel elbow
1. By manufacturing standards can be divided into the national standard, the electric standard, water standard, American standard, Germany standard, Japanese standard, the standard and so on.
2. By producing method can be divided into pushing, pressing, forging, casting, etc.
90 ° in the white steel elbow is mainly used in pipe installation, a connecting pipe fittings, used for connection pipe bend. Connect two of the same nominal diameter tube, and make the line to turn 90 degrees.
Stainless steel does not rust, corrosion resistance as the main features, and at least 10.5% chromium content, carbon content does not exceed 1.2% of the largest steel.
