Hyspan designs and manufactures a comprehensive selection of products for industrial pipe motion applications in paper mills, steel mills, cement plants, fluid storage tanks, cryogenic fluid transfer, pharmaceuticals, and other process sites.

Most applications involve absorbing thermal expansion or contraction; however, other applications involve vibration isolation and relative motion compensation for tank and building 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 venturis. Sizes range from 1” (25mm) through 20’ (6m). Complete metal bellows and hose assemblies with flanges, pipe, or tube ends are provided from 321, 304/304L, and 316/316L. Formed metal bellows are also available in Alloy 625, Alloy 718, Alloy C22, Alloy C276, and B265 Grade 2 Titanium.

Although the product selected can be a standard Hyspan configuration or an adaptation of a standard, many industrial applications are custom designed to meet specialized requirements and demanding customer specifications. Hyspan staff 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 ASMEB31.1, ASME B31.3, and ASME Section VIII Division 1 codes. European Pressure Equipment Directive (PED) standards, with CR 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. Quality personnel are certified to the standards of the American Society of Nondestructive Testing (ASNT). Hyspan is a member of the Expansion Joint Manufacturers Association (EJMA ®). A copy of our Hyspan EJMA ® certificate is available.
