A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.

A method for the individualized adaptation of the shape of components includes providing a basic material for producing the components. Next at least one unifying production method is selected. The components are then produced with a geometrically identical base shape by the unifying production method. Then at least one individualizing production method is selected. Then the shape of the components is adapted to at least two different final shapes by the individualizing production method that is different from the unifying production method. The final shape of each component differs from its basic shape.

A two-section assembly chamber includes a section S1 (11) and a section S2 (12), whose shapes are selected between cylindrical, where section S1 (11) has a diameter larger than the section S2 (12), and in the shape of a conical frustum, where sections S1 (11) and S2 (12) form a conical frustum, where the conical frustum begins at S1 (11) with the wider part and ends at S2 (12) with the narrower part, both sections S1 (11) and S2 (12) are joined or welded together, and are removable, each having respective caps (21, 22), wherein the assembly chamber has at least one perforation for introducing a pressurized fluid. The assembly chamber is configured so that a tube (30) or a second chamber, which has a larger diameter than the section S2 (12), is assembled within the inner diameter of the section S2 (12).

A forming device includes: a fluid supply unit that is disposed at an end portion of a metal pipe material and that supplies a fluid into the metal pipe material through an opening of the end portion; and a sealing mechanism that performs sealing against leakage of the fluid from the metal pipe material when the fluid is supplied by the fluid supply unit into the metal pipe material that is heated by a heating unit, in which the sealing mechanism performs the sealing by contact between the metal pipe material and a non-resin material, without applying an axial force to the metal pipe material.
