rectangular pipe expansion joint / axial / lateral / angular

Rectangular expansion joints are used in case the duct cross-sections are rectangular instead of circular. The ondulations are higher with a larger width.
The types of rectangular expansion joints are named acording to the corner design as.

RECTANGULAR EXPANSION JOINTS TYPES

ROUNDED CORNER
SINGLE MITER CORNER
CAMERA CORNER

Movement Absorption

Axial shift and slight all-around movement of the expansion joint is possible. Axial expansion joints with two bellows are used to absorb larger movements.

Advantages of Axial Expansion Joints

? Easy to absorb the expansion movements
? No direction changes of the flow
? Minimum application area
? Possible lateral and angular expansion absorption by the additional bellows.
? Low application costs
