    • PROBLEM TO BE SOLVED: To provide a coating spray material that, when applied to form a lining on a pipe with a bent portion, can uniformly and efficiently form a rust-preventing coating film on the inside wall of the pipe without requiring any large-scale apparatus or facility.
      SOLUTION: The coating spray apparatus of the present invention is used in a lining method for forming a coating film on the inside wall of a pipe. It is provided with a coating feed part 110 that feeds a coating material used in lining and a tubular coating spray nozzle 120 that sprays a coating material fed from the coating feed part 110. A flow resistor 122 that controls the flow rate in the central part in a flux of a coating material passing the coating spray nozzle 120 is provided in the central part of the inside diameter of the coating spray nozzle 120. The flow resistor 122 adjusts the difference between the flow rates at the peripheral and central parts in a flux of the coating material which passes the coating spray nozzle 120.

    • PROBLEM TO BE SOLVED: To provide an apparatus for coating the inside of a pipe by which the repairing work of the inner surface of a hollow steel pipe can efficiently be performed.
      SOLUTION: The apparatus for coating the inside of the pipe is provided with: a coating unit having a nozzle part 11 having a nozzle formed to spray a liquid, and a supply tube 13 connected to the nozzle part 11 at one end and communicating with a supply device 12 for supplying the liquid at another end; and a suction unit having a suction tube 15 arranged near the nozzle part 11 at one end part and communicating with a suction device 14 at another end part and a hermetically sealing member 16 capable of hermetically sealing the inside of the hollow steel pipe 3 by abutting on the inside surface of the hollow steel pipe 3 and sucking the inside of the hollow steel pipe hermetically sealed with the hermetically sealing member 16. The supply tube 13 and the suction tube 15 are hung into the hollow steel pipe 3 from the upper end opening of the hollow steel pipe 3 to substantially evacuate the hollow steel pipe 3 by the suction unit and to coat the inner surface of the hollow steel tube 3 by a coating unit.
