换热机组管子的翻边与开槽

  换热机组管子翻边能增加管口的抗拉脱力泛亚电竞官网,当管子受压应力时泛亚电竞官网,就不用翻边。一般翻边量约3mm左右,翻边后呈圆锥状,过大的翻边角易形成裂纹,实际中大多采用12°角的翻边泛亚电竞官网。

高效管式换热机组
  换热机组管孔开槽是增加拉脱力最有效的方法泛亚电竞官网,为了提高胀接管抗拉脱能力和密封可靠性泛亚电竞官网,管孔大多采用开槽的结构泛亚电竞官网。不仅增加管子摩擦力,而且增加了密封面积,管孔开环形小槽深为0.4~0.5mm,管板厚度小于30mm时,槽数为1泛亚电竞官网,厚度大于30mm时,槽数为2泛亚电竞官网,强度胀一般开两个槽,厚度板可开更多的槽。
