A forming system includes: a forming apparatus which supplies gas into a cylindrical metal pipe material having a welded portion to expand the metal pipe material; a supply device for supplying the metal pipe material to the forming apparatus; and a control device for controlling an operation of the supply device, in which in a case where a position where a distance from a center of the metal pipe material is the longest, on a surface of the die, when viewed from an extension direction of the metal pipe material in a state where the metal pipe material is disposed between the dies, is a longest position, the control device includes a control unit which controls supply of the metal pipe material to the forming apparatus such that the welded portion is not located on a straight line connecting the longest position and the center of the metal pipe material.

Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end. An automated installation procedure installs the end fitting through the use of multiple chucks, positioned by servo motors along a fitting table.

The invention relates to a method for induction bend forming a compression-resistant pipe (I) having a large wall thickness and a large diameter. According to said method, in an initial phase t1, an initial tangent (3) of the pipe (I) is heat-treated by pushing the initial tangent (3) through the inductor (20) without the intervention of the bending lock (31). At the end of the initial tangent (3) the advance of the pipe is stopped at a time t2, and the inductor (20) is moved along the pipe (I) counter to the advance direction while the bending lock (31) is closed on the pipe (I). In order to induce the bending process in a phase t3, the movement speed of the inductor (20) is reduced to zero and the latter is moved to its bending position. At the same time, the advance of the pipe (I) is started. In a phase t4, a pipe bend (4) is produced at a constant process advance speed of the pipe (I). In a phase t5, the advance speed of the pipe (I) is reduced and the inductor (20) is accelerated counter to the advance direction while the bending lock (31) is opened. In a phase t6, a final tangent (5) is heated by further advancing the inductor in the opposite direction.
