Apparatus for applying a fluid material to the inner wall of a tube

Abstract

An apparatus for applying a fluid material to the inner wall of a tube (600) comprises a controller (100), a supply device (200), and an operating device (300) located outside the tube (600), and an operating device (400) releasably inserted into the tube (600), wherein the supply device (200) is configured to selectively supply the fluid material to the operating device (400) under the control of the controller (100), the operating device (400) comprises a spray cup (463) on which, when the spray cup (463) is rotated, the fluid material supplied to the spray cup (463) is spun radially outward from the spray cup (463), and the operating device (300) is configured to allow the operating device (400) to be movable within the tube (600) when the operating device (400) is inserted into the tube (600). The fluid material can be easily applied to the inner wall of the tube.
