Plate Flanges and elbow are common accessories in engineering. Plate Flanges and elbows can be seen in the hardware area or fastener area of many large-scale exhibitions at home and abroad. However, flat flange and elbow belong to different categories respectively. There are great differences between Plate Flanges and elbow in terms of manufacturer, process, shape, standard, purpose and product details. Shanxi Haokun Flanges Group Co., Ltd., as a factory specializing in the production of Plate Flanges, explains various differences for you.
1. They are all used in the pipeline system, but the Plate Flanges is the simplest flange with flat surface and no groove. For connecting pipes, Plate Flanges cannot change the direction of the pipeline. If you need to change the direction of the pipeline, you need to use elbows. According to the classification of different directions, the three main categories are 45 °, 90 ° and 180 °. In addition, according to the needs of the project, it also includes 60 ° and other abnormal angle elbows. This is the main difference from Plate Flanges. This also determines the obvious difference in appearance between Plate Flanges and elbow.
2. Different raw materials. The raw materials of Plate Flanges are mainly carbon steel, stainless steel and alloy steel. Elbows also include cast iron, malleable cast iron, non-ferrous metals and plastics. This is not available with Plate Flanges. Therefore, the chemical properties of Plate Flanges are higher.
3. There are many ways to connect with the pipe: elbow is directly welded (commonly used), flange connection, hot-melt connection, electric fusion connection, threaded connection, socket connection and so on. The Plate Flanges is connected with the pipe, which is directly welded with the pipe to realize the connection.
4. Different classifications: Plate Flanges are classified according to standard materials. Elbows are classified according to different production processes and angles.
5. Different uses: Plate Flanges is mainly used for water treatment, offshore devices and oil and gas engineering, while elbow is mainly used for plumbing installation.
