1. PIPE REQUIREMENTS
  • Pipe 1" through 8" - Thermalok Style
    • Pipe is manufactured from electric resistance welded carbon steel pipe. Pipe conforms to ASTM A587 in 1" - 4" sizes, and A53 Gr. B in sizes 6" and 8". 1" - 8" pipe conforms dimensionally to Schedule 40.
    • Pipe is also available in stainless steel, type 304 or 316. Stainless steel pipe conforms to ASTM A312.
    • Pipe is vented on the housing by means of small vent holes (1" - 4" = 3/32"; 6" - 8" = 5/32"), allowing permeant vaports to escape. Pipe spools up to 18" in length receive (1) vent hole in the center of the pipe. Pipe spools longer that 18" in length receive (2) vent holes, one at each end, aligned on same side of the pipe.
    • The liner is mechanically locked to the interior of the steel pipe via the Thermalok process. The PTFE liner is first molded oversized, such that it will not fit in the pipe housing. The liner is then drawn through a sizing die into the pipe housing. Next, the liner and pipe are put in an oven, where the liner is thermally relaxed into the pipe housing, causing a tight interference fit. Pipe is available as "factory flared" with locked liner, or "field flare" (at least one plain end) with movable liner.
    • Stainless steel MULTI-AXIS® pipe is available in 1" through 4" sizes.

  • Pipe 1" though 8" - Swaged Style
    • Pipe is manufactured from electric resistance welded (ERW) normalized ASTM A513 C-1010 aluminum killed carbon steel tubing with chemical composition meeting ASTM A587, a diamond picked spiral groove interior and is limited with polytetrafluoroethylene (PTFE) or perfluoroalkoxy (PFA).
    • The diamond picked interior provides a path for permeants to escape at the flange face venting collar.
    • The liner is mechanically locked to the interior of the steel tubing by swaging the steel tubing to nominal pipe size (NPS) dimensions.
    • Finished steel pipe dimensions 1" through 6" are Schedule 40.
    • Finished steel pipe dimensions 8" are Schedule 30.
    • MULTI-AXIS pipe is available in 1" through 4" size.

  • Pipe 10" and 12" - Full Vacuum
    • Pipe is manufactured from ERW ASTM A53, Grade B carbon steel with a smooth interior and is lined with PTFE by the Thermalok process. The metal pipe is Schedule 30 in 10" size, and Schedule 20 in 12" size.
    • Pipe is also available in stainless steel type 304 or 316. Stainless steel pipe conforms to ASTM A312.
    • Pipe is vented on the housing by means of 5/32" dia. vent holes, allowing permeant vaports to escape. Pipe spools up to 18" in length receive (1) vent hole in the center of pipe. Pipe spools longer than 18" in length receive (2) vent holes, one at each end, aligned on same side of the pipe.
    • 10" and 12" pipe with the "Full Vacuum" designation is rated for full vacuum at 450°F.

  • Pipe 10" and 12" - Non-Vacuum
    • Pipe is manufactured from ERW ASTM A53, Grade B, Type E carbon steel with a smooth interior and is lined with PTFE by a reverse swaging process.
    • Four 1/8" diameter vent holes equally spaced are located 1-1/2" from each end of the pipe. On pipe shorter than 18", only one end has vent holes.
    • Finished steel pipe dimensions are Schedule 30.

  • Minimum lengths available are:

  • Pipe 10" and 12" is available in either "Full Vacuum" (up to 450°F) or "Non-Vacuum" styles.

5. STORAGE AND HANDLING REQUIREMENTS:
  • Avoid dropping or impacting pipe with heavy objects or storing near high traffic areas.
  • Uninstalled lined pipe should not be stored or handled at temperatures below 0°F (-18°C).
  • The center of gravity for pipe can be very deceptive. Use extra care in handling, transfer, and storage of the product to avoid sudden load shifting causing possible personal injury and/or product damage.
6. PAINT:
Paint is a two-component primer,formulated on proprietary polymer technology, which provides rapid cure and overcoating even under low temperature conditions. The maximum external temperature rating for the paint is 212°F (100°C).
7. INSPECTION AND QUALITY CONTROL:
  • 1" - 8" swaged-style and 10" and 12" non-vacuum pipe passes a 15,000 volt minimum electrostatic spark test to ensure integrity of the plastic liner. 1" - 8" Thermalok pipe and 10" and 12" Full Vacuum pipe passes either of the following test: a 12,500 volt 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 end protectors are used to protect the plastic faces for flanged pipe. Plastic end caps are used to protect the plastic liner for plain end pipe. End protectors should stay in place until immediately prior to installation.
  • Flanged pipe is labeled with a sticker located on the wooden end protectors which identifies the plastic liner type and the flange material. Plain end pipe is labeled with a sticker located on the pipe which identifies the plastic liner type.
