A form-rolling device for processing a tubular member may include a shaft rotatable around a first axis, a first grooving portion that protrudes from an outer circumference of the shaft; a second grooving portion that is rotatable around a second axis parallel to the first axis; a flange-shaped tube-end positioning member that is attached to a position of the outer circumference of the shaft nearer to a base end than the first grooving portion, and a supporting member that supports an outer circumference of a ring member held on an outer circumference of the tubular member.

A pipe connection device according to the present invention includes: a connection member including a projection in which an insertion space is formed in the projection and a pipe is inserted through one side and which is bent in a circumferential direction at the other side and a separation preventing unit which is spaced apart from the projection and protrudes in the circumferential direction; and a flange member coupled to the circumference of the connection member between the projection and the separation preventing unit so as to contact the projection and having a joining hole penetrated by a joining member.

A tube and method for sizing the effective inside diameter of the tube to a smaller effective inside diameter is provided. The method uses rollers that apply focused pressure to the tube to create a crease that reduces the effective inside diameter without substantially changing the outside envelope of the tube. The crease may be either a radius or squared. Reducing the effective inside diameter of the tube creates radiused surfaces for a self-tapping screw to cut threads.

In a corrugated plate manufacturing apparatus, each of a plurality of primary forming punches includes a plurality of primary pressable portions that are arranged one after another in a slider reciprocating direction and are pressable by a corresponding one of a plurality of primary sliders. When the primary sliders are sequentially moved toward one side in the slider reciprocating direction, each corresponding one of the primary sliders presses the primary pressable portions of the corresponding one of the primary forming punches to press the primary forming punch against a secondary die.
