A squeeze roll stand includes a combination of a fixed portion installed at a joint position of an electric resistance welded pipe manufacturing line, in which squeeze rolls excluding left and right upper rolls are detachably assembled, and a movable portion overlying the fixed portion, inside which left and right upper rolls are detachably assembled, the movable portion being inclined, taking a back surface downstream side as a fulcrum point, toward a same side from an assembling position on the fixed portion to a retreat position to open an upper part of the fixed portion. The movable portion is driven and reciprocated between the assembling position and the retreat position with cylinder type actuators as a drive mechanism. At the retreat position, the movable portion overlies a bead grinding device arranged on the back surface downstream side of the fixed portion with a front surface facing upward.
