法蘭、法蘭類零件

     法蘭是一種盤狀零件，在管道工程中最為常見，法蘭都是成對使用的。 在管道工程中，法蘭主要用于管道的連接。在需要  法蘭盤連接兩個管道的端頭處，各安裝一片法蘭盤，低壓管道可以使用絲接法蘭，4公斤以上壓力的使用焊接法蘭。兩片法蘭盤之間加上密封墊，然后用螺栓緊固。 　　不同壓力的法蘭有不同的厚度和使用不同的螺栓。 　　水泵和閥門，在和管道連接時，這些器材設備的局部，也制成相對應的法蘭形狀，也稱為法蘭連接。 　　凡是在兩個平面在周邊使用螺栓連接同時封閉的連接零件，一般都稱為“法蘭”，如通風管道的連接，這一類零件可以稱為“法蘭類零件”。

The flange is a discoid parts, in pipeline engineering are the most common, flange are used in pairs. In the pipeline project, mainly used for pipeline flange connection. In need of flangeConnecting two pipe ends, each provided with a flange, pipe can use wire connecting flange, 4 kilograms of above pressure using welding flange. Two ring flanges coupled between sealing pad, and then the bolt fastening. Different pressure flange having different thickness and the use of different bolt. Pumps and valves, and pipeline connection, these equipment locally, also made the corresponding flange shape, also known as the flange connection. In two planes in the peripheral using bolt connection at the same time the closed connecting parts, generally referred to as" flange", such as ventilation pipeline connection, the parts can be called" flange type parts".
