Jacketed Tubing and Insulated Tubing

Swagelok® jacketed tubing helps provide increased protection against galvanic and atmospheric corrosion. Swagelok insulated tubing is designed for use in applications such as steam supply, condensate return, and gas and liquid transport lines, where weatherproofing and energy conservation are important. Swagelok insulated tubing offers a cost-effective alternative to field-installed insulation of small-diameter tubing systems.

  • Stainless steel tubing available seamless and welded
  • Low-temperature PVC jacket helps protect tubing from external corrosion and abrasion
  • Fibrous glass insulation reduces heat loss and helps protect personnel
  • Insulation contains less than 100 ppm of water-soluble chlorides
  • Marked with part number and batch number
  • Insulated tubing is available with urethane jacket material and in colors other than the standard black
  • Accessories include
    • Bending tool
    • Heat-shrink end-seal boots
    • Silicone sealant
    • Jacket patch kit
    • Caps
    • Weatherproof strip insulation

Jacketed, Pre-Insulated Tubing Bundles—Electric-Traced and Steam-Traced

Swagelok pre-insulated traced tubing bundles provide reliable process temperature maintenance in a variety of analytical and process instrumentation applications, including impulse lines, sample lines, and process lines and provide an economical choice compared to field tracing and insulating. The parallel configuration—process and tracer lines are parallel inside the bundle—allows all tubes to bend together in as little as an 8 in. (20.3 cm) radius in tubing sizes up to 3/4 in. or 12 mm, so the bundle is easier to route and connect in the field than cabled bundles. Also available in multi-jacketed configurations.

  • Water soluble chlorides less than 100 ppm
  • Absorption-resistant fibrous glass insulation
  • Resists wicking
  • Accessories include:
    • Bending tools
    • Heat-shrink end-seal and entry-seal boots
    • Jacket patch kits
    • Center line tool
    • Silicone sealant
    • Controllers and thermostats
    • Electric tracers: power connection, tracer termination, and tracer splice/tee connection kits

Electric-Traced Tubing

Swagelok electric-traced bundled tubing maintains consistent temperatures in long, continuous lengths of impulse and sample lines for freeze protection, temperature maintenance up to 250°F (121°C), or viscosity control

Steam-Traced Tubing

Swagelok light steam-traced bundled tubing is typically used for freeze protection of instrument impulse lines and analyzer transport lines. It can also maintain temperatures in smaller diameter process lines from 50 to 200°F (10 to 93°C).

Swagelok heavy steam-traced bundled tubing is typically used to maintain higher process temperature from 200 to 400°F (93 to 204°C) or for viscosity control. Applications can include impulse, sampling, and process lines.
