Is there a special kind of hinge for bi-fold doors?

[Fergal]

Hi all

I wish to convert the door of the boiler cupboard in my kitchen into a bi-fold by cutting it down the middle lengthways and joining the two halves back together with some hinges. The cupboard is in the corner and I need to reduce the distance that the door swings out (it is currently 600mm wide) so that I can mount a new cupboard next to it on the adjacent wall.

Is there a special kind of hinge used for joining the two halves of a bi-fold door, or will a normal flap hinge do the job?

Thanks

Fergal

Piano hinge is what I have always used.
