孔凸缘与孔仪结合使用以测量由管道输送的油,气体和其他液体的流速。孔凸缘以多种尺寸和材料等级制造给ASME B16.36。
什么是孔板法兰?
孔板法兰用于测量管道通过位于法兰上的流量喷嘴输送的流体的流量。在孔板法兰上加工成对的压力抽头,使得在管壁上不需要单独的抽头。
传统的孔板法兰组件由一对法兰、孔板、螺栓、螺母、垫片、顶螺丝和塞组成。顶压螺丝确保容易拆卸一级流动元件。
孔板法兰可在所有ASTM锻造等级(ASTM A105, ASTM A350, ASTM A694, ASTM 182分别为碳,合金和,不锈钢法兰),尺寸(公称尺寸和组合压力评级)并且,在插座焊接中,螺纹或焊接颈部形状(WN是最常用的)。


表中数据说明:
- 尺寸为毫米(不包括螺栓和螺栓孔)。
- 提供不同的NPT尺寸超过1/2
- 对于nps1到nps12, RF法兰的螺栓长度包括孔口和垫片厚度6毫米(0.25英寸)的余量。对于nps1到nps3,环型连接法兰的螺栓长度允许为15毫米(0.62英寸)。
- 孔(B)必须由买方指定
- 螺柱螺栓长度不含。倒角的高度
