知道不锈钢法兰直径,怎么确定垫片的尺寸(垫片内加强聚乙烯氟) 法兰直径(φ133mm)(φ

数据太不全了,要知道法兰的压力和公称通径才可以判定,而且密封面的形式不同配对的垫片也不一样。 只给出一个外径尺寸来只能看猜测了。

首先对一下标准,看看是否属于标准法兰。如果是非标法兰,就只能按照密封面位置确定垫片尺寸了。垫片内径按照法兰最内侧(最小)孔径确定即可;一般密封面位置中间处都有水纹线,切记垫片上的聚乙烯四氟部分的内外径必须与密封面一致。垫片最外圈直径须较螺栓孔内侧稍小,以便紧固法兰时放入螺栓后垫片顺利就位及准确定位。

查一下法兰对于的是什么通经的,即DN。相同法兰配相同垫片就是。垫片和法兰式相匹配的

应该知道下管道的内径(管子外径-壁厚),与垫子内径一致就可以了,外径就算挡住螺栓孔了,裁一下就好了

不锈钢法兰好多都是外径-5,厚度-3.你给的这些参数,不能确定法兰的大小。垫片就没有办法配了。 一般标准的法兰,与垫片都一一对应的。

如果是化工用法兰,就查GB/T20615-2009,法兰的所有尺寸都能对应查出来,这样再来确定垫片的形式及尺寸。
