1. MATERIAL REQUIREMENTS:
  • Resin
    • PTFE is virgin polytetrafluoroethylene.
    • PVDF is polyvinylidene fluoride homopolymer.
    • PP is a Type I homopolymer polypropylene with 30% E-glass milled fibers.
    • All resins conform to the requirements of ASTM F1545.

  • Liner Colors:
    • PTFE spacers are unpigmented and white.
    • PVDF is pigmented black.
    • PP is pigmented orange.

  • Thickness:
    • The nominal thickness for reducing, standard, blind, and armored full face and ring spacers is 1/2" (13 mm) for 1" through 8" pipe sizes and 3/4" (19 mm) for 10" and 12" sizes.
    • The thickness of single and double taper and orifice full face and ring spacers, and of lined steel ring spacers is produced per customer specifications.

  • PTFE lined steel ring spacers are lined with unfilled PTFE virgin resin.
  • Steel for ring spacers is SAE 1010-1030 or ASTM A516 GR 70 carbon steel plate.
  • Steel for 1" through 8" armored spacers is manufactured from normalized ASTM A513 C-1010 aluminum killed steel tubing with chemical composition conforming to ASTM A587.
  • Steel for 10" and 12" armored spacers conform to ASTM A53, Grade B, Type E.
  • Metal wall thickness of steel armored spacers is 1/4" (6 mm).

2. TEST REQUIREMENTS
  • Service Temperature:
    PTFE: -20°F (-29°C) to 450°F (232°C)
    PVDF: 0°F (-18°C) to 275°F (135°C)
    PP:    0°F (-18°C) to 225°F (107°C)
Note: Operating temperature limitations may be encountered depending upon specific chemical environments.

B.   Pressure: For Class 150 and 300 service, the maximum thickness recommended is 3" (76 mm). The preferred option to spacers is customized pipe spools.

3. INSPECTION AND QUALITY CONTROL:
  • Each spacer sealing surface is visually inspected for defects.
  • Products are impression marked for material traceability.
