WELDLESS CORNERED RECTANGULAR MULTIPLY EXPANSION JOINTS

When the use of rectangular expansion joints is necessary, welded corners are usually produced. The highest mechanical stresses are concentrated in the corners and weldings become the weakest links of the whole structure.

Our expansion joints are manufactured in such a way that no welding appears on the corners, only one appears on the longitudinal side.

Kompaflex is the only manufacturer able to master such technique.

1) Multiply construction
2) Easier welding inspection
3) No welding seams in the critical corner area
3) Higher flexibility and higher movements of bellows
3) Longer life of expansion joints
