Advantages: Compared with the flat welding flange or butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines which are not allowed to be welded on site. Alloy steel flange has enough strength, but it is not easy to weld, or welding performance is not good, can also choose threaded flange.
Disadvantages: It is recommended not to use threaded flange to avoid leakage when the pipeline temperature changes rapidly or the temperature is higher than 260 鈩?and lower than - 45 鈩?
