Expansion joints

Axial expansion joints for the absorption of axial movements, i.e. movements along the expansion joint.

• axial movement absorption of up to approx. 200 mm possible
• low absorption of lateral and angular movements possible
• unanchored: movement on all sides possible. High axial forces in conjunction with high pressure

Universal expansion joints comprise two metal bellows interconnected by a central tube.

• absorption of axial, lateral and angular movements possible
• unanchored: movement on all sides possible. High axial forces in conjunction with high pressure

Lateral expansion joints are suitable for the absorption of lateral movements, i.e. transversely to the pipe axis of the expansion joint.

• absorption of lateral movement
• one-way flexibility with single pivot bolt bracing
• universal flexibility with cardan joint bracing
• bracing for absorbing the axial compressive forces (no axial movement possible)

Angular expansion joints absorb movements in the form of angular movements.

• absorption of angular movements
• one-way flexibility with single pivot bolt bracing
• mobility in all directions with tie rod bracing or cardan joint bracing
• bracing for absorbing axial compressive forces (no axial movement possible)

Standard designs of axial expansion joints for steel, stainless steel and copper pipes in building utilities. The optimal product range for all applications in water and heating circuits and gas installation.

• nominal diameters ranging from DN 15 to DN 250
• provided with screw connections, threaded sockets, threaded nipples, flanges or welding ends

Specially designed for designers, "FLEXPERTE" is a PC software application for dimensioning and presenting expansion joints, metal bellows, flexible metal hoses and pipe supports. The menu-based application aids in the calculation and design of these products.

• intuitive operation
• tailor-made design even of complex load chains
• Rohr2, CAESAR II, PDMS and PDS interfaces
