Preferably the apparatus comprises a pair of fittings with pivot mountings receivable in both ends of the pipe section, means for forcing the fittings toward each other in a direction axial of the pipe and for initially applying slight transverse pressure to the pipe section intermediate its ends in a direction radially outward with respect to the desired bend, and parallel planar guides on opposite sides of the pipe section.
