Method for forming and mounting protective material for end of large-diameter steel pipe

Abstract

Abstract PURPOSE:To facilitate production and to reduce cost to a greater extent by using a quick setting type molten resin and executing simultaneously forming and mounting of protecting material for a pipe end. CONSTITUTION:The molten resin of the quick setting type discharged from a resin discharger A is supplied to a discharge gun 5 mounted to a stand 6 via a heater hose 7. A nozzle formed to the shape conforming to the end shape of a steel pipe 3 is provided to the front end of the gun 5. The molten resin supplied thereto is cooled to solidify by the steel pipe 3 of ordinary temp. The molten resin is supplied to the discharge gun while the steel pipe 3 is kept rotated by turning rolls 4 at this time. Then, the molten resin solidifies successively and the mounting of the protective material 1 for the pipe end is completed simultaneously with the formation thereof.
