The thick-walled elbow connecting pipe member comprises an arc-shaped elbow, which is characterized in that there is a split-through straight connection on the curved elbow. Thick wall elbows are made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics. According to the production process, it can be divided into: welding elbows, punching elbows, casting elbows, etc. The way in which thick-walled elbows are connected to pipes is: direct welding (commonly used) flange joints, threaded joints, and socket-type joints.
The thick-walled elbow structure is reasonable, the pipe system can be evenly stressed, the pipe system can be simplified, the operation is convenient, the investment can be saved, the pipe resistance can be reduced, the pipe arrangement can be optimized, the operation cost can be reduced, the airflow distribution can be balanced, and the pipe can be reduced. Vibration and ensure safe operation of equipment and piping. According to the production process, it can be divided into: welding elbows, punching elbows, casting elbows, etc.
