Method for coating pipe
Abstract
Abstract A METHOD AND APPARATUS FOR COATING A PAIR OF PIPE SECTIONS UTILIZES SPACED, PARALLEL, TRACK VEHICLES FOR MOVING THE SECTIONS ON OPPOSITE SIDES OF A CENTRAL COATING STATION. COATING MATERIAL IS ALTERNATELY SUPPLIED FROM THE STATION TO TWO APPLICATORS, WHICH ARE LOCATED ADJACENT AND PERPENDICULAR TO THE RESPECTIVE TRACKS, BY A REVERSIBLE FEEDER BELT. MOVEMENT OF THE SECTIONS IS FORWARD TO THE COATING STATION AND THEN BACKWARD AWAY FROM THE STATION. THE PIPE SECTIONS ARE SPACED APART IN THEIR DIRECTIONS OF TRAVEL SO THAT THEIR PATHS ARE 180* OUT OF PHASE AND ONE OF THE SECTIONS IS AT THE FOWARD END OF ITS PATH OF TRAVEL WHILE THE OTHER IS AT THE BACKWARD END OF ITS PATH OF TRAVEL. THUS, ONE SECTION CAB BE SUBJECTED TO THE COATING STEP WHILE THE OTHER SECTION IS BEING REMOVED FROM THE TRACK VEHICLE. D R A W I N G
