Hyspan designs and manufactures a comprehensive selection of products for power piping applications. Both equipment and balance-of-plant expansion joints and hoses are supported. Most applications involve thermal expansion or contraction. Other needs require vibration isolation and relative motion compensation for tanks, building and structure settlement, seismic isolation, structural support, and flow measurement.  

For more than a half-century, we have designed, engineered, manufactured, tested, and acquired various expansion joint technologies. This unique and extensive experience provides Hyspan exceptional capabilities in this critical industry.  

Hyspan’s complete line of products includes metal bellows expansion joints, packed expansion joints, ball joints, metal hoses, and accessory products such as pipe guides, strut joints, hydraulic vibration snubbers, and flow measurement venturis.  

Although the product selected can be a standard Hyspan configuration or an adaptation of a standard, many power applications are custom designed to meet specialized requirements and demanding customer specifications. Hyspan can meet challenging engineering problems and manage major contracts.  

Hyspan is an ISO 9001:2015 registered company with a quality system that supports requirements of the piping and boiler pressure vessel codes. These include popular ASME B31.1, ASME B31.3, and ASME Section VIII Division 1 codes. European Pressure Equipment Directive (PED) standards, with CE markings, can be supported in many applications. Canadian Registration Number (CRN) support is available. 

Nondestructive testing and inspections are performed by company personnel including radiography.
