摘要： PURPOSE:To inhibit the invasion of ultraviolet-curing paint into a pipe, when the pipe passes through a paint liquid-supply means, by properly setting the direction of spraying the paint liquid when the front and rear ends of the pipe go through. CONSTITUTION:When the front end of a pipe 2 goes through a position in front of the heads 4, 4' of a paint liquid-supply means, the angle of the heads 4, 4' is controlled in a manner such that the paint is ejected with an angle theta1 against a pipe-carrying direction so that its velocity component vix along the pipe- carrying direction is larger than the carrying speed (v) at the point where the flying locus 20 of the paint liquid comes in contact with the front end of the pipe 2. While the central part of the pipe 2 is passing through, the angle of the heads 4, 4' is deviated to a reversal direction against the pipe-carrying direction. When the rear end of the pipe 2 goes through the position in front of the heads 4, 4', the angle of the heads 4, 4' is controlled in a manner such that the velocity component v2x along the carrying direction is smaller than the carrying speed (v) at the point where the flying locus 20 comes in contact with the rear end of the pipe 2, and the paint liquid is ejected with an angle theta2. Consequently, coating work is performed without the invasion of the paint into the pipe at its front and rear ends.

摘要： PURPOSE:To obtain a desired temporary corrosion-preventing property without the whitening or peeling of a film, by mixing special synthetic resin powder in polymerisable composition reactive with active energy rays, applying the composition to a pipe or rod article, and curing it with the irradiation of the energy rays. CONSTITUTION:To 100pts.wt. polymerisable composition comprising 30-90wt% a compound containing one polymerisable unsaturated group, which is reacted with active energy rays, per one molecule, 5-30wt% a compound having two or more of said groups and molecular weight above 300 with the proviso that the total of the first and second compounds is at 35-95%, and the balance being styrene (its deriv.), etc., 1-20pts. synthetic resin powder insoluble to the composition at an ordinary temperature, e.g. polyethylene, is compounded. Said composition is applied a a coating agent to a workpiece to be coated such as a pipe or rod and immediately cured with the irradiation of active energy rays by using a high pressure mercury lamp or the like. According to this method, temporary corrosion-preventing treatment which precludes the whitening or peeling of the film caused by contact, etc. during conveyance can be performed.

摘要： PURPOSE:To eliminate uneven paint application with high coating efficiency, by conveying longitudinally a plurality of metal pipes arranged in parallel while rotating the metal pipes, applying rust preventing paint which can be cured with short-time ultraviolet rays irradiation or the like onto the outer surfaces of the metal pipes, and curing the paint. CONSTITUTION:A plurality of metal pipes 1, 1' arranged in parallel are rotated and conveyed longitudinally by a conveying roller 2, and rust preventing paint (e.g. unsaturated acryl ultraviolet-curing paint) which can be cured with the short-time irradiation of ultraviolet or electron rays is applied to the outer surfaces of the pipes 1, 1' by a spray nozzle 4 in a coating chamber 3. Thereafter, ultraviolet or electron rays are immediately applied from the lower and/or upper sides of the pipes 1, 1' by an irradiating lamp 7 in an irradiating chamber 6 so that the paint is cured until the pipes come in contact with the next conveying roller 2''.

摘要： PURPOSE:To inhibit the adhesion of paint liquid to the front end surface of a pipe, by supplying the paint to the outer periphery of the pipe, scrubbing the paint with an elastic body having a special configuration provided with an opening, and then removing the paint liquid ahderent to the elastic body by using compressed air or the like. CONSTITUTION:After ultraviolet-curing paint is supplid to the outer periphery of a pipe, the pipe is passed through a scrubbing means 10 comprising a rubber elastic plate 12 or the like having an opening 11 to uniformly apply the paint to the outer periphery of the pipe. In this case, a plurality of nozzles are provided apart from the elastic body 12 between the paint-supply means and the scrubbing means 10, to blow off excess paint liquid adherent to the elastic body 12 by spraying compressed air to the position where the pipe comes in contact with the elastic body 12, etc. According to this method, the adhesion of the paint liquid to the front end surface of the pipe can be prevented without injuring uniform paint-application to the outer periphery of the pipe.
