Expansion joints manufacturer | Metal Expansion Joints

LBH Metal Expansion Joints are designed and manufacture as single-, or multiply metal bellows.

Designed for use in any application in sizes from DN40.

Bellows are made in stainless steel, nickel alloys or titanium combined with various flanges and pipe designs.

Design calculations are possible acc. to EJMA, EN and ASME
