Series 320 Hand-Built Pressure Piping Expansion Joint with Tire Industry Technology
Greater performance than other expansion joints on the market because of the polyester tire cord and modified arch construction
- Superior movement capabilities solve piping movement challenges without having to use long and expensive multi-arch products
- Available in a filled arch which eliminates flow turbulence and the collection of suspended solids
- Increased strength, flexibility, and safety compared to traditional hand-built expansion joints
- Precise guidelines for pressure/vacuum capabilities at various temperatures
- Recommended for high flow velocity and high abrasion conditions
- Axial extensions, axial compression, lateral deflection, and angular movement
Series 320EZ Light Weight Expansion Joint (inventory stock item)
Excellent movement in compression, extension, lateral, angular deflection and torsional movements
- Light weight construction for ease of handling and reduction in freight costs, up to 50% less weight
- Saves money and time by requiring a lighter anchoring system and less reinforcement
- Lowest spring rates in the industry; Ideal for FRP Piping
- Reduces stress load with lower reaction force and springs rates which saves money and time
- Recommended for temperatures up to 225°F for Buna-Nitrile and 300°F for EPDM
- Excellent pressure capacity for low, standard and most high pressure designs
- Available in stock at 1 1⁄2” ID through 20” ID and standard face-to-face dimensions with retaining rings
Series 320M Molded Expansion Joint (inventory stock item)
Molded piping expansion joint results in a nicer finished product than hand-built products
- Greater performance than other expansion joints on the market because of the polyester tire cord and modified arch construction
- Available materials: Nitrile, EPDM, Teflon-Lined
- Available in a variety of sizes, 1 1⁄2” to 20” and 24” to 72” diameter, standard face-to-face dimensions
- All sizes will achieve a full vacuum and are supplied with ANSI150# drilled flanges
- Recommended for temperatures up to 300°F
Series 980 Floating Flange Rubber Expansion Joints
