Abstract

Disclosed is an apparatus for conveniently and rapidly removing chips from the interior of a pipe by discharging chips with a portion of fluid out of the pipe using the difference between the pressure in the pipe and atmospheric pressure. The apparatus includes a fitting mounted to a region adjacent to a hole bored in a pipe, a sandwich valve coupled to the fitting, a chip-removing adapter mounted above the sandwich valve, a suction tube extending to an inner surface of the pipe through the chip-removing adapter in order to remove chips from the pipe, a vertical moving unit for vertically moving the suction tube, a delivery tube connected to an upper end of the suction tube and configured to deliver the chips to a predetermined place, and a strainer mounted to a distal end of the delivery tube in order to separate the delivered chips from the fluid.

Abstract

A double plug head for plugging a pipe. The double plug head includes a primary rubber packing, a roller support, a tube support and a rubber tube. The primary rubber packing is provided on a mounting plate of a plugging machine. The roller support is provided with a plurality of rollers. The tube support is provided between the primary rubber packing and the roller support. A tube seating depression is formed around the circumferential surface of the tube support. A fluid feed path is formed in the tube support. The rubber tube is seated into the tube seating depression and has a nipple connected to an outlet of the fluid feed path. Communication holes which communicate with the fluid feed path are respectively formed in the primary rubber packing and the mounting plate. A fluid hose is connected to the communication hole of the mounting plate.
