The end shapes can be selected from among the above seven basic shapes (or eight depending on manufacturing methods) and the following special shapes. (But type T&T is not possible)


Closed end O.D of end is almost the same as I.D O.D of type B's end<O.D of end<O.D
O.D of end is almost the same as O.D I.D<O.D of end<O.D of type A's end
Special shapes are combinations of typeA ~ F in the following figure.

Example:C&E combination

* If you don't specify the thickness of metal for the thick part of typeT, we will use our standard thickness.
* As for the thick part of typeT, you can open holes or process it in concavo-convex way.
* Semi-seamless metal bellows are not producible as typeT.
* For typeA,C,E, and F, there are limitations even on the producible thickness, depending on the length and diameter.
