A bend is a pipe that changes the direction of the line. Points according to the Angle 45 ° and 90 ° 180 ° three kinds of commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend. The bent material has cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic etc. The way to connect the pipe is: direct welding (commonly used) flange connection, fusion connection, electric fusion connection, thread connection and socket connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, pushing bend, casting bend, welding elbow, etc. Other names: 90 degrees elbow, right Angle bend, love and bend etc.
