Series 320 Hand-Built Pressure Piping Expansion Joint with Tire Industry Technology

  • Holz 320 pipe expansion joint for high flow velocity and high abrasion conditions

    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)

  • Holz 320 ez light weight pipe expansion joint

    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)

  • Holz 320 molded pipe expansion joint

    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

Holz Pipe Expansion Joints for Piping
