  厚壁焊管双色球万能缩水加工工艺和成型方法有哪些

  厚壁焊管双色球万能缩水产品不仅类型丰富,而且关于其的加工工艺和成型方法也多式多样。大多数情况下,在成型之后,******一道工序都是对焊接后管坯再进行一次全长扩径,以提高焊接管形质量。也就是说,扩径工艺成为了大口径直缝焊管生产中确保成品管质量的一道重要工序。

  总的来说,在对厚壁焊管产品经扩径加工的过程中,主要可以分为五个阶段。第一是初步整圆阶段:扇形块打开直到所有扇形块都接触到钢管内壁,此时步长范围内钢管内圆管中各点半径大小都几乎一致,钢管得到初步整圆。第二是名义内径阶段:扇形块从前段位置开始降低运动速度,直到抵达要求位置,这个位置是质量要求的成品管内圆周位置。
