Bellows Expansion Joint
Bellows model
NK-8900 Hinge type Bellows Expansion Joints
Features
Our NK-8900, Hinge type Bellows Expansion Joint absorbs angular displacement on a single level.
As its motive, weight, external force caused by inner pressure of the bellows are supported by hinge-arm and
hinge-pin. This means only force of the angular displacement comes onto the communal area of the anchor of
plumbing and equippments of the machine, which is the most suitable to unstable plumbings.
The installation chart that follows, the expansion of the plumbings can be absorbed properly by one motion of
axial vertical or angular displacements or by countinuous movements with support of two or three hinge type
bellows expansion joints.
