锻打法兰(flange)又叫法兰盘或突缘盘。
Flange is also called flange or flange plate.
锻打法兰是在铸钢法兰的基础上所发明成产的，其强度比铸钢法兰要高很多。
Forging flange is invented and manufactured on the basis of cast steel flange. Its strength is much higher than that of cast steel flange.
锻打法兰是管子与管子相互连接的零件，连接于管端。锻打法兰上有孔眼，螺栓使两法兰紧连。锻打法兰间用衬垫密封。锻打法兰管件(flanged pipe fittings)指带有锻打法兰(突缘或接盘)的管件。它可由浇铸而成(图暂缺)，也可由螺纹连接或焊接构成。法兰连接(flange，joint)由一对法兰、一个垫片及若干个螺栓螺母组成。垫片放在两法兰密封面之间，拧紧螺母后，垫片表面上的比压达到一定数值后产生变形，并填满密封面上凹凸不平处，使连接严密不漏。法兰连接是一种可拆连接。按所连接的部件可分为容器法兰及管法兰。按结构型式分，有整体法兰、活套法兰和螺纹法兰。常见的整体法兰有平焊法兰及对焊法兰。平焊锻打法兰的刚性较差，适用于压力p≤4MPa的场合；对焊法兰又称高颈法兰，刚性较大，适用于压力温度较高的场合。
Forging flange is a part of pipe and pipe connected to each other, connected to the end of the pipe. There are holes in the forged flange, and the bolts make the two flanges close together. The forged flanges are sealed with gaskets. Flanged pipe fittings refer to pipe fittings with forged flanges (flanges or joints). It can be cast (drawings are missing), or it can be made of threaded joints or welding. Flange connection (joint) consists of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed fuzhou.89ix.comhaikou.89ix.com shanghai.89ix.comtianjin.89ix.comchongqing.89ix.comxin.75ix.combetween the sealing surfaces of two flanges. When the nut is tightened, the specific pressure on the gasket surface reaches a certain value, and then deforms, and fills the uneven parts on the sealing surface, so that the connection is tight and leaky. Flange connection is a detachable connection. Container flange and pipe flange can be divided according to the components connected. According to the structure type, there are integral flange, looper flange and thread flange. Flat welding flange and butt welding flange are common integral flanges. Flat welding forged flange has poor rigidity, which is suitable for pressure P < 4 MPa occasion; butt welding flange is also called high neck flange, which has high rigidity and is suitable for high pressure and temperature occasions.
