Product Description

Series 6500 Perma-Pax Packed Expansion Joints

Series 6500 Packed Expansion Joints are designed for installations where the principal movement is axial. Standard single and dual designs are available 2″ through 24″ diameter with travels of 4″, 8″ and 12″ compression for single designs, and 8″, 16″ and 24″ compression for dual designs. Service conditions are 150 and 300 psig to 500°F. Welded and flanged end connections are standard, with grooved ends optional.

Technology & Advantages

Series 6500 expansion joints incorporate design features that are not available from other manufacturers. They include a one piece body which eliminates a circumferential weld, line bored aluminum bronze metal inner and outer guides, and an optimized sealing system consisting of carbon fiber graphite impregnated braided packing combined with Grafoil® Flexible Graphite injected packing.

These features combine to provide a standard product with the lowest seal resistance force available, self lubrication, and precision internal metallic guides. Series 6500 products are available from stock and include a Five year full replacement warranty.

Common Applications

Series 6500 expansion joints are designed for installations where the principal movement is axial. Standard single configurations are designed for 4″, 8″ and 12″ of axial compression (pipe expansion) and 1″, 1.5″ and 2″  extension respectively. Dual configurations are designed for 8″, 16″ and 24″ of axial compression and 2″, 3″ and 4″ extension respectively. If the primary movement is extension (pipe contraction), the expansion joint can be preset at the factory. The piping system must include anchors to react the force produced by pressure thrust and the friction force, to react the weight of the pipe and media, and guides to ensure that the pipe alignment is maintained.

Design Data

Note:

(1) Distance measured is from the face of the expansion joint. Recommend distance 10–14 pipe diameters. Tabulated values are based on 12 pipe diameters.
(2) Tabulated values are based on Hyspan Series 6500 friction forces and standard weight carbon steel pipe. Distances are center to center. Pressures are design values. Guide spacing has been calculated for test pressure (1.5 X design.)
(3) Tabulated values are the maximum recommended—source ASME 31.1 Power Piping Code.

Linear thermal expansion of pipe per 100 feet between 70°F and the tabulated temperature.

The tabulated values in Columns 5 and 6 are measured in inches per 100 feet of pipe run.

The Seal Force, Column 3, is the maximum value allowed. Each joint is cycled and the value measured for quality assurance.

Note: Add 1.25″ to the values in Column 3 for injectors with optional 1/4 turn valves.

Note:

(1) Refer to Table 3 for pressure thrust and friction force.
(2) For Type 6505 and 6506 the travel stated is the total. Travel each side of the anchor base is 1/2 of the tabulated value.
(3) Refer to Table 4 for the housing outside diameter, packer clearance, drain port size, centerline height for anchor base models, and anchor base details

Single expansion joints, 6501 and 6502, ordered with anchor based are identified as 6501AB and 6502AB. Anchor bases are standard on dual anchor base joints, 6505 and 6506, and do not require the AB suffix.

Optional features must be specified by a written description accompanying the part number. Options that are available include:

  • Higher rated pressure and temperature
  • Alternate materials
  • Vent or instrumentation ports
  • Factory preset of overall length
  • Service outlets (size and orientation must be specified)
  • Grooved end attachments
  • 1/4 Turn valve on each injector fitting
  • Threaded adjusting rods for field preset
