法兰理论重量表
平焊法兰
平焊法兰是指与容器或管道采用角焊缝连接的一种法兰。属任意式法兰。设计时根据法兰环与直筒段连接的整体性程度，分别按整体式或松式法兰校核。法兰环有带颈和不带颈两种。与带颈对焊法兰相比，平焊法兰结构简单，用材省，但刚度及密封性不如带颈对焊法兰。平焊法兰广泛应用于中低压容器和管道的连接。
中文名：平焊法兰
外文名：Flat welding flange
简称：平板
别称：搭焊法兰
焊接方法：快速
结构生产工艺材质原理及特点重量表
概况
板式平焊钢制管法兰，带颈平焊钢制管法兰
平焊法兰适用于压力等级比较低，压力波动、振动及震荡均不严重的管道系统中。平焊法兰优点在于平焊法兰焊接装配时较易对中，并且价格比较便宜，因而得到了广泛的应用。
大型平焊法兰
CB M1001-81
使用压力PN0.25MPa ,PN0.6MPa ,PN1.0MPa,PN1.6MPa ,PN2.5MPa，PN4.0MPa
产品类别全平面板式法兰（FF），突面板式法兰（RF)
制造材料不锈钢(304、316等)、碳钢（20# 25#等）
垫片使用
垫片是一种能产生塑性变形、并具有一定强度的材料制成的圆环。大多数垫片是从非金属板裁下来的，或由专业工厂按规定尺寸制作，其材料为石棉橡胶板、石棉板、聚乙烯板等；也有用薄金属板(白铁皮、不锈钢)将石棉等非金属材料包裹起来制成的金属包垫片；
还有一种用薄钢带与石棉带一起绕制而成的缠绕式垫片。普通橡胶垫片适用于温度低于120℃的场合；石棉橡胶垫片适用于对水蒸气温度低于450℃，对油类温度低于350℃，压力低于5MPa的场合，对于一般的腐蚀性介质，最常用的是耐酸石棉板。在高压设备及管道中，采用铜、铝、10号钢、不锈钢制成的透镜型或其他形状的金属垫片。高压垫片与密封面的接触宽度非常窄(线接触)，密封面与垫片的加工光洁度较高。
