Metal bellows provide the unique ability to absorb axial, lateral, and angular motions in a small area. Thermal, settlement, and seismic motions can be accommodated along with stress reduction. Vibration reduction at rotating equipment is also provided with laminated bellows technology.

Hyspan designs and manufactures metal bellows expansion joints ranging in diameter from 3/4″ (19mm) NPS through virtually any diameter. Single-ply and multi-ply bellows are provided. Multi-ply bellows technologies include concurrent laminations of 2, 3, 4, 5 or more plies, and 2-ply redundant or testable. Welded assembly of a bellows expansion joints assures a leak-free product at installation without mechanical seals. Internal and external pressure designs are available.

Hyspan manufactures in the United States and Mexico.

Hyspan is the single source for expansion compensation, seismic connections and vibration isolation in heating, ventilation and air conditioning systems. Only Hyspan manufacturers metal bellows expansion joints for axial and offset applications, packed slip expansion joints, ball joints, metal hose assemblies and refrigeration connectors. These products provide an unequaled ability to fill every application with the correct product. Hyspan’s engineering staff is available to help with product selection as well as representation located throughout the world that is staffed with trained application engineers.
