摘要： PURPOSE:To efficiently clean up the inside surface of steel pipe, by providing a plurality of link-type expansion supports around the machine and attaching wheels to the outer ends of the supports and installing an air ejection nozzle to eject air downward to the inside surface of the pipe. CONSTITUTION:When the inner diameter of the cleaned steel pipe 9 changes, the center line of the cleaning machine 3 is automatically positioned on that of the steel pipe 9 and the machine 3 is kept stable in a fixed position simply by simutaneously expanding the link-type expansion supports 4. The machine 3 ejects the air downward to the inside surface of the steel pipe 9 so that spatters, slag, rust, scales, etc. scraped off by a grinder from the inside surface of the pipe 9 are easily blown away. Namely, it is not necessary to separately prepare trucks exclusive for the respective diameters of steel pipes. The machine can be easily and quickly adjusted to the difference in the inner diameter of the steel pipe. The machine is made compact and light. Thereby, the operation of the machine is facilitated.

摘要： PURPOSE:To obtain transfer time suited for pipe laying operation, by making an efficient use of idle time and thus reducing the time required for transforring operation, without increasing the speed of each process. CONSTITUTION:A plurality of short pipes 1B, 1C, etc. are placed on pipe supporting bed 3a of charging means 3, and vertically movable beam 7 is moved upward, together with carrier 8, by expanding cylinders 13, while positioning short pipe 1B correctly upwards of the carrier 8. In case that pipe 1A is on the pipe laying line, the beam 7 is stopped at position 7', and then cylinders 16 incorporated in the carrier 8 are expanded to transfer the short pipe 1B onto pipe supporting bed 15. When the pipe 1B on the bed 15 is raised to position A, driving means 9 is set into operation to move the carrier 8 position B by means of chain or rolls 10a, 10b. When the pipe 1A is removed, carrier 8 is shifted from position C to position E, and bed 15 is lowered, thus completing the pipe transferring operation.

摘要： PURPOSE:To bend a pipe without damaging the surface of the pipe by holding three points of the pipe at equal intervals and giving pressing force to the center and giving reaction force to both sides by extension of a jack. CONSTITUTION:A pipe 11 to be worked is passed through a pipe plunger punch 10 and fitted to pipe receiving dies 7, 9. When a hydraulic jack 1 is extended, jack seats 12, 14 move in the direction to separate from each other and consequently, compression beams 2, 4 turn around pivots 17, 18 in the direction to part from each other. An axis 20 to which plunger punch pulling beams 3, 5 and a cross joint 19 are pivoted moves to approach the hydraulic jack 1. At the same time, the pipe plunger punch 10 is moved to approach the hydraulic jack 1 by the cross joint 19 through clamp arms 21, 22. Thus, pressing force is given to the pipe 11 by the pipe plunger punch 10 and reaction force is given by pipe receiving dies 7, 9, and the pipe 11 is bent.
