    摘要: Invention relates to is a mandrel adjustment assembly for multi-wall pipe made of a coated metal sheet comprising; a bearing positioning an elongated mandrel over a tray by holding; a distance adjustment unit having an adjustment member adjusting a stroke distance of mandrel by changing axial location of bearing; a first support and a second support holding mandrel over a tray such that the mandrel is freely movable between a distal end and an opposite proximal end. A distance adjustment unit is equipped with a display enabling visual access to a stroke distance set by an adjustment arm and the distance adjustment unit move the mandrel over the tray providing a displacement equal to stroke distance.
