Elbow is a commonly used pipe installed in connection with a pipe connecting two nominal pipe diameter the same or different, so the pipeline for a certain angle turn in the piping system, pipe elbow is to change the direction of the tube components in piping systems used in all the fittings, the largest proportion, about 80% are usually of different materials or thickness of the bend forming process to select a different present, commonly forming process seamless elbow hot pushing, punching, squeezing, etc. in accordance with the production process can be divided into: welding elbow, pressing elbow, push the system elbow, casting elbow, etc. in order to create standards can be divided into standard electricity, water, standard, American standard, Germany standard, Japanese standard, the Russian standard, etc. Our standard virtuous elbow elbow, elbow on standard, American standard elbow, etc. elbow commonly used materials are cast iron, stainless steel, alloy steel, forging iron, carbon steel, non-ferrous metals and plastics, etc. and the pipe coupling ways: direct welding (the most common way), flange connection, hot melt connection, fused connections, threaded connections and socket type connection, etc.
