    法兰连接法也是与铸铁管及钢管之间最简单的连接方法,而法兰盲板则可用于检查口的开口上.

      法兰就是两个大口径管道的连接装置,通常是两个法兰片加若干紧固螺栓。碳钢法兰就是碳素钢制成的法兰。低碳钢塑性好强度低,加入适量碳元素后就会变得坚硬,塑性降低强度增强。法兰连接有可能需要承受很高抗拉、抗压、抗扭、抗剪强度,碳钢法兰就是较好的选择。  一般用在管道上,那样的话,松掉螺栓可以旋转两边的管道,再拧紧可以较方便的拆装管道材质是碳钢的法兰叫碳钢法兰。
      法兰连接法也是与铸铁管及钢管之间最简单的连接方法。而对焊法兰则可用于检查口的开口上。另外,法兰连接适用于管径从φ50-315mm的管件连接。其性能特点:非刚性连接、可拆装、抗拉力。法兰连接法通常作为低压输送管线上可拆卸的连接件。
       承插式伸缩短管连接法适用于管径从φ32-315mm的管件连接。其性能特点:非刚性连接、可拆装、抗拉力。安装承插式伸缩短管连接件,必须使用锚固管卡进行固定,以防止在热胀冷缩中承插管位置的移动。在楼板与楼板间的垂竖立管上、长距离的收集管网上以及埋地管道必须至少安装一个承插式伸缩短管。这是因为承插式伸缩短管不仅能消除由于排水过程温度变化引起的热胀冷缩,而且有助于与各个楼面支管的连接,使得管道安装更为简单。
