A UNIVERSAL DEVICE TO SUPPORT AND MAINTAIN CONSTANT GAP TO AVOID SHRINKAGE DURING WELDING OF EVAPORATOR PANELS WITH BEND TUBES IN HIGH PRESSURE BOILERS

摘要

The invention relates to a universal device to support and maintain constant gap to avoid shrinkage during welding of evaporator panels with bend tubes in high pressure boilers, comprising; -a handle (01) with a locking pin (04) and a ratchet assembly (05) having outer arms (03) on both sides of the ratchet assembly; and - a plurality of studs (06) welded to a plurality of semicircular clamps (02), wherein the rotation of the handle (01) allows the externally-threaded stud (06) to simultaneously move longitudinally in opposite direction, and wherein the plurality of the clamps corresponding to the movement of the stud (06) firmly grip the work piece (07,08) to maintain a predetermined constant gap.
