摘要： PROBLEM TO BE SOLVED: To collect and recover metallic powder easily and in a short time concurrently with the drilling work for a branch hole. SOLUTION: Metallic powder, produced at the time of drilling in a main tube 1, is attracted by an attracting ring 49 by fitting it, provided with a permanent magnet 48 in an inner side, to the inner peripheral surface of a cylindrical cutter 44. Since the metallic powder can be recovered without shutting off the flow of fluid in the tube 1, providing a drain to a connecting tube 2, etc., as conventionally is eliminated, consequently, the useless flow of the fluid from the drain, and also the flow of flammable fluid are eliminated.

摘要： PROBLEM TO BE SOLVED: To easily cut a fluid pipe without using a closed case, a large cutter, etc., by cutting the fluid pipe by sending a cutting tool inserted from an opening part of one part toward a center of the fluid pipe while rotating a case and closing the opening part of the case by removing the cutting tool thereafter. SOLUTION: A channel of a branch pipe 8 is closed by projecting a gate valve 11 by operating a gate valve device 9 after drawing up a rotating cutting tool 16 above the gate valve 11 by contracting and retreating a hydraulic cylinder 13. Thereafter, an installing part is closed by removing the gate valve device 9 after hermetically closing a flange 8a of the branch pipe 8 by installing a blocking plate on its by removing all of the hydraulic cylinder 13, a rotating actuator 15, etc., with a cylinder bracket 12 from the branch pipe 8. Finally, construction is finished by backfilling the exposed fluid pipe 11 by leaving only a case 3 as an expansion flexible pipe fitting by removing both of left and right support 19, a motor 21, etc., as well as removing a ring gear 18 installed on the case 3.

摘要： PROBLEM TO BE SOLVED: To suppress excessive pressure contact force on a fluid pipe caused by packing so as to prevent stress relaxation by forming a clearance for inducting the deformation of the packing on an outside of a butt joint part of circular arc shaped packings. SOLUTION: When a first joining part 4f and a second joining part 4g are butted against each other to bring them into pressure-contact deformation caused by compression is induced to a first clearance 8 formed by an inclining part 4i. Since it is fitted to a housing recessed part 7 which is protruded and arranged on an outer periphery of the first and second joining parts 4f, 4g and formed on a surface opposed to a flange 3, a butt-joint direction of the first and second joining parts 4f, 4g and a direction for fastening the flange 3 are matched with each other, it is not released in a pipe axial direction when they are brought into pressure-contact with each other, thereby applying fastening force effectively. When a packing is compressed so as to generate deformation, excessive pressure-contact force on a fluid pipe can be suppressed, and also water stop property in the butt-joint surface can be improved.

摘要： PROBLEM TO BE SOLVED: To safely change the auxiliary valve for air valve with the simple operation without surrounding the periphery thereof with a sealing case or the like and without cutting off the fluid inside of the existing pipe. SOLUTION: An auxiliary valve 4 is connected to a connection port 3 of an existing pipe 1, and in an air valve 2 connected to the auxiliary valve 4 through a connecting pipe 5, a divided T-shaped pipe 8 having a branch cylinder B is installed in the connecting pipe 5, and a hole drilling device 10 or a water- stop valve 14 is fitted to the branch cylinder B, and the inside of the connecting pipe 5 is sealed by this water-stop valve 14, and in this condition, a housing case, in which a sealing member 19 having an operating shaft 18 is housed, is connected to the top of the connecting pipe 5 through a working valve 16. The sealing member 19 is lowered from the housing case 17 and inserted into the connection port 3, since the connection port 3 is shielded by the sealing member 19 operated by the operating shaft 18, the auxiliary valve can be changed with a new auxiliary valve in relation to the existing pipe 1 with the simple operation without surrounding the periphery thereof with a sealing case or the like and without cutting off the fluid inside of the existing pipe 1.
