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.

Electric-Traced
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
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.
