Spool Type Double Arch
Spool Type Double Arch Expansion Joint
The Spool Type Double Arch Expansion Joint by Connectall LTD is designed for superior flexibility and increased movement absorption compared to single-arch types. With two precision-formed arches, it allows greater angular, lateral, and axial movement while reducing spring rate and mechanical vibration in high-performance systems. This joint is ideal for demanding environments such as pumping stations, HVAC systems, and industrial process lines where frequent pressure fluctuations occur.
Available in a range of premium elastomers—including EPDM for high-temperature and chemical resistance, Neoprene for general-purpose durability, Nitrile for oil and fuel service, and Hypalon or Chlorobutyl for specialized chemical and ozone resistance—this expansion joint can be customized for virtually any application.
Connectall LTD’s engineering team evaluates system design factors such as pressure, temperature, and movement range to recommend the optimal double-arch configuration, ensuring maximum system reliability and reduced maintenance costs.
