Welding Neck Flanges (RFWN Flange) are easy to recognize. They include a long tapered hub that gradually meets the wall thickness from the pipe or fitting. The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures.

1、法兰SO-RF: SO表示平焊法兰，RF表示密封面形式为突面，即突面密封平焊法兰。 2、法兰WN-RF：WN表示对焊法兰，RF表示密封面形式为突面，即突面密封对焊法兰。 3、法兰BL-RF：BL表示法兰盖，又称 盲板 法兰，RF表示密封面形式为突面，即突面密封盲板法兰。 法兰用于管端之间的连接，也有用在设备进出口上的法兰，用于两个设备之间的连接，如减速机法兰。 法兰连接或法兰接头，是指由法兰、 垫片 及螺栓三者相互连接作为一组组合密封结构的可拆连 …

法兰（Flange），又叫法兰凸缘盘或突缘。 法兰是轴与轴之间相互连接的零件，用于管端之间的连接；也有用在设备进出口上的法兰，用于两个设备之间的连接，如减速机法兰。 法兰连接或法兰接头，是指由法兰、垫片及螺栓三者相互连接作为一组组合密封结构的可拆连接。 管道法兰系指管道装置中配管用的法兰，用在设备上系指设备的进出口法兰。 法兰上有孔眼，螺栓使两法兰紧连。 法兰间用衬垫密封。 法兰分螺纹连接（丝扣连接）法兰、焊接法兰和卡夹法兰。 法兰都是成 …

RFWN Flanges stands for Raised Face Weld Neck Flange. In RFWN flanges the gasket surfaces are raised above the bolting circle face. This helps to concentrate more pressure on a smaller gasket area and thus increase the pressure containment capability of the joint.

What is a RFWN flange? RFWN Flange (Raised Face Weld Neck Flange): A Raised Face Weld Neck (RFWN) flange is a type of flange that combines the features of a weld neck flange and a raised face flange. This specific flange design is widely used in various industries for connecting pipes, valves, and equipment, offering a robust and reliable ...
