摘要： PROBLEM TO BE SOLVED: To certainly and easily prevent the depression, peeling or flaw of an outer surface resin coated metal pipe in a manufacturing method for the outer surface resin coated metal pipe using a feed conveyor and heating.
SOLUTION: In a process for continuously heating a metal pipe 3, a heat- shrinkable resin pipe 2 is externally fitted to the outer surface of the metal pipe by hot air or the like, while feeding the same in the direction crossing the pipe axis of the metal pipe 3 at a right angle to produce the outer surface coated metal pipe 4. An ejector device 30 is arranged on the lateral side of the feed conveyor 10, an ejector fixture 31 having a semicylindrical projected part 31a provided to the upper part thereof is raised by an air cylinder 32, and the outer surface coated metal pipe 4 is rotated in a feed direction along the semicylindrical upper surface by ejection to alter the contact position of the outer surface resin and the feed surface. This process is successively repeated to prevent the generation of a cavity or the like due to surface pressure or the like.

摘要： PURPOSE: To inhibit the exfoliation of a coating film or the formation of scratches, by making a conveyer and a receiving stand for receiving a tubular body sent out from an applicator freely followable to the carrying speed of said tubular body.
CONSTITUTION: A coated tubular body after being coated with an applicator 5 is carried and accepted by a conveyer 6 constituting a let off motion. Hereon, a longitudinal moving speed is set synchronizedly with the carrying speed of said conveyer 6. Hence, any slip between the tubular body 1 supported on a receiving stand through a supporting mechanism and the conveyer 6 does not occur, so that the exfoliation of a coating film, the formation of scratches, etc. can be inhibited.

摘要： PURPOSE:To provide a metallic pipe with a rugged coated film of a synthetic resin, by vibrating a molten synthetic resin or intermittently chaning the feed rate of a metallic pipe when coating the pipe with the resin. CONSTITUTION:An adhesive 3 such as a modified polyethylene resin base adhesive is preliminarily coated on the outside surface of the metallic pipe 2, and a molten synthetic resin 5 is extruded through a circular die 1. The die 1 is fitted with an extra low frequency vibration genrator 4 and is vibrated, whereby a complicated transverse wrinkle form rugged pattern is generated in the resin 5 being extruded, and the rugged pattern remains as it is at the surface of the resin after the resin is coated on the pipe 2. Alternatively, the rugged pattern is formed on the surface of a coated film 5 of the synthetic resin by a method wherein feed rools 6 for the metallic pipe 2 are alternately rotated forwardly and reversely when coating the resin on the pipe 2.
