*Reducing filler flanges are available in carbon steel or stainless steel up to 30" dia.
Note: Rotationally-lined "Complex Shapes" are available lined with Tefzel® ETFE through 30" dia. Housing and flange material can be carbon steel or stainless steel. These include manifolds, branched elbows, reducing laterals, double and triple branch instruments tees, etc, per customer requirements. Tefzel® liner is unpigmented. Check Resistoflex chemical resistance data for max. use temperature of Tefzel® with various media. Liner selection is responsibility of the customer. Contact factory for more information.

6. FITTING REQUIREMENTS - STAINLESS STEEL:
7. LINER REQUIREMENTS:
  • Resin is PTFE or PFA conforming to the requirements of ASTM F1545.
  • Liners are unpigmented. PTFE is white in color; PFA is clear.
Note: Standard fittings are available to provide 450° full vacuum performance if so specified. Some fittings may have a reduced vacuum rating - please refer to the vacuum tables for details.

C.   The minimum outside diameter of the plastic sealing surface per ASTM F1545 is:

Size Minimum Sealing Diameter
(NPS) (Inch) (Millimeters)
1" 1-7/8" 48
1-1/2" 2-11/16" 68
2" 3-7/16" 87
3" 4-5/8" 117
4" 5-15/16" 151
6" 8" 203
8" 10-1/16" 256
10" 12-1/4" 311
12" 14-3/8" 365

D.   The minimum liner flange face thickness is 0.100" (2.54 mm).

8. OPERATING REQUIREMENTS:
  • Service temperature:
     For PTFE (carbon steel or DI housing and flanges):
       -20° F (-29°C) to 450°F (232°C)
     For PFA:
       0°F (-18°C) to 450°F (232°C)
Note 1: PTFE-lined stainless steel fittings can be used at lower temperatures than shown above. Please consult technical services for details.
Note 2: Operating temperature limitations may be encountered depending upon specific chemical environments.

B.   Pressure: The maximum allowable working pressure equals the corresponding ASNI pressure-temperature rating per the designated metallurgy.

C.   Vacuum: 1"-12"fittings are available with full-vacuum capabilities. Consult Resistoflex product publications, web site, or factory for specific temperature/vacuum ratings. Complex Shapes vacuum rating is undetermined. Testing can be provided at an additional charge.

9. STORAGE AND HANDLING REQUIREMENTS:
  • Avoid dropping or impacting fittings with heavy objects or storing near high traffic areas.
  • Uninstalled lined fittings should not be stored or handled at temperatures below 0°F (-18°C).
10. PAINT
Paint is a two component epoxy primer, formulated on proprietary polymer technology, which provides rapid cure and overcoating even under low temperature conditions. The maximum external temperature rating is 212°F (100°C). Note: Stainless steel fittings are not painted.

11. INSPECTION AND QUALITY CONTROL:
  • 100% of PTFE-lined fittings shall pass a 12,500 - 15,000 volt electrostatic test or a 425 psig hydrostatic test. These tests are designed to verify the integrity of the plastic liner. ASTM F1545 specifies that the lined pipe manufacturer may employ either test. Complex Shapes shall receive either a 12,500 volt minimum electrostatic test or a 425 psig hydrostatic test.
  • All parts pass visual inspection.
  • The sealing surface of the liner is free of defects that would impair sealing effectiveness.
  • Wooden or plastic end protectors are used to protect the plastic faces. End protectors should stay in place until immediately prior to installation.
  • Fittings are labeled with a sticker which identifies the plastic liner type and the flange material.
  • Color Band Coding:
    • Fitting liner material is identified by a color band as follows:
  • Products are available impression marked for material traceability.
