Insulated Tubing Gives You Temperature Control

Because it differs from ordinary tubing, so do the installation instructions

There are times when ordinary tubing alone won't get the job done. One of those times is when you need to control the temperature of the fluid inside, or control the surface temperature of the tubing itself. That's when you might want to consider insulated tubing - download the catalogue below.

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. It helps protect personnel from hot process and steam lines, reduces heat loss, and offers a cost-effective alternative to field-installed insulation of small-diameter tubing systems.

Tubing lengths and bends

Because the tubing itself is different, so is the installation procedure.

First consider the length of tubing. You'll want to allow at least 12 inches of straight tubing before connecting it to fittings. For steam-trace tubing bundles, add enough length to connect the tracer to the supply connection and to the return connection. For electric-traced tubing bundles, add enough length to connect to the power supply. Include 6 inches for inside the junction box. Don't forget to include extra length to heat any other devices at the end of the bundle. Also, use the approved power connection and termination kits.

You'll want to use a centerline tool when you are bending tubing bundles to connect them to instrumentation. Start by cutting and removing the jacket and insulation on the tubing, so that you can see the process and tracer tubes. Insert the tube bundle through the seal boot in the tool, unscrew the center nut, and remove the center bend shoe. Now you'll be able to fully insert the tube bundle and gently bend the tubes against the outer shoes.

Install the center bend shoe and tighten the center nut. Bend the tubes against the center shoe until the tubes are parallel. Insert the tube bundle through the seal boot again, and remove the tubing bundle from the tool. To protect the insulation, seal the bundle ends with a heat shrink end seal boot.
