|20140183774||METHOD AND DEVICE FOR PRODUCING A PIPE MEMBER - An object of the present invention is to provide a method for producing a pipe, which is capable of reducing the amount of thermoplastic material, without complicating an device for producing a pipe. The present invention provides a method for producing a pipe, comprising a thermoplastic material filling process for filling a die with a thermoplastic material, and a thermoplastic material discharging process for pushing out an unsolidified part of the thermoplastic material in the molding die using pressurized fluid, wherein the thermoplastic material is mixed with a foaming agent, the method further comprises a process for foaming the thermoplastic material filling the molding die, and the thermoplastic material discharging process is a process for pushing out a inner part of the thermoplastic material foamed in the molding die, by using the pressurized fluid prior to solidification of the inner part.||07-03-2014|
|20130154255||PIPE FITTING - A pipe fitting having a main body portion into which a retainer is inserted and which, when inserted over a pipe, a flange provided to the pipe contacts first taper portions formed to a front side of the retainer, pushes out the first taper portions, and passes by the retainer. When the main body portion is pulled off the pipe, the flange contacts second taper portions formed to a rear side of the retainer, pushes out the second taper portions and passes by the retainer.||06-20-2013|
|20130047691||PIPE BENDING PROCESSING APPARATUS - An object of the invention is to provide a compact and inexpensive pipe bending processing apparatus. To attain this object, provided is a pipe bending processing apparatus which positions a pipe with respect to a bending roll in response to the rotation of a rotary shaft, and bends the pipe by moving the pipe along the bending roll while pressing the pipe against the bending roll, wherein an outer cylinder in which a linear slit is formed along a bus line and a circumferential slit extending in a circumferential direction is formed at an upper end of the linear slit is arranged in a machine casing, an inner cylinder formed with a spiral groove is rotatably arranged inside the outer cylinder, the rotary shaft is inserted into the inner cylinder so as to be vertically movable and rotatable, a pin is provided in a protruding manner at the rotary shaft and is inserted into the spiral groove of the inner cylinder and into the linear slit of the outer cylinder, the inner cylinder is linked to an output shaft of a rotary actuator, and the rotary shaft is lifted and is also rotated at an uppermost position by the rotary actuator.||02-28-2013|
|20110011226||METHOD FOR EXPOSING RESIN-COATED METAL PIPE - A method of exposing a metal pipe that is resin-coated by which part of the resin coating layer can be easily removed to expose the metal pipe. Blade tips are advanced into a resin coating layer in a region of the circumferential surface of a pipe with a predetermined spacing in the longitudinal direction of the pipe, and circumferential notches are introduced into the circumferential surface of the resin coating layer by rotating blades with respect to the pipe. A blade tip is advanced into a resin coating layer between the two circumferential notches and by moving a blade in the longitudinal direction, a longitudinal notch is introduced into the circumferential surface of the resin coating layer. A force is caused to act upon an outer circumferential surface of the resin coating layer between the two circumferential notches in the direction opposite that of the longitudinal notch and the resin coating layer is peeled off, thereby exposing a portion of the metal pipe.||01-20-2011|
