Method for coating pipe

Abstract

Abstract A METHOD FOR COATING PIPE WHICH CONSISTS OF TRANSPORTING A PIPE SECTION TO A HEATING STATION BY MEANS OF A FIRST CARRIER DEVICE, ROTATING THE PIPE SECTION DURING THE HEATING THEREOF, TRANSPORTING THE HEATED PIPE SECTION TO A FIRST COATING APPARATUS BY MEANS OF A SECOND CARRIER DEVICE, ROTATING THE HEATED PIPE SECTION AND SIMULTANEOUSLY APPLYING AN INITIAL LAYER OF COATING MATERIAL TO THE EXTERIOR OF THE PIPE IN A LONGITUDINAL DIRECTION THEREALONG, TRANSPORTING THE INITIALLY COATED PIPE SECTION BY THE SECOND CARRIER TO A SECOND COATING STATION, SIMULTANEOUSLY ROTATING THE PIPE SECTION AND APPLYING A SECOND LAYER OF COATING MATERIAL TO THE EXTERIOR OF THE PIPE SECTION IN A LONGITUDINAL DIRECTION THEREALONG, AND PLACING THE COATED PIPE SECTION ON SPECIAL SADDLES AND SUBSEQUENTLY TRANSPORTING THE PIPE SECTION BY A THIRD CARRIER DEVICE THROUGH A POST CURE HEATING STATION, AND ROTATING THE COATED PIPE SECTION PASSING THROUGH THE POST CURE HEATING STATION. ALTERNATIVELY, THE SECOND COATING MAY BE APPLIED WHILE THE PIPE IS STILL SUFFICIENTLY HOT TO EMIMINATE THE SECOND HEATING OPERATION.
