From the view of kinds of copper elbow, there are 45 ° and 90 ° 180 ° three copper elbows are the most commonly used, in addition, including 60 ° angle elbow.
In the piping system, the copper elbow is to change the direction of the tube line. The materials of copper elbow are as follows: casting iron, stainless steel, alloy steel, forging iron, steel, nonferrous metals and plastics. The ways to connect copper elbow with the pipe: direct welding (the most common way), flange connection, threaded connection, and socket type couplings and so on.
According to the production process, the copper elbows can be divided into: welding elbow, punching elbow, casting copper elbow and so on. The copper elbow has other names, such as 90 ° elbow, right elbow and so on.
Finally, the usage of copper elbows: to connect two same nominal diameter pipes and to make pipe for 90 degree turning.
1. The elbows can be divided by materials into carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, aluminum elbow, plastic elbow and so on.
2. The copper elbow can be divided by production methods into the system, pressing, forging, and casting and so on.
3. The copper elbow can be divided by creating criteria into national standards, electricity standard, the water standard, American standard, Germany standard, Japanese standard, the Russian standard and so on.
