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.
