What is a tubing bundle?
A tubing bundle is a small diameter tube or group of tubes packaged in an insulated, weatherproofed jacket. It's steam or electric traced to provide freeze protection or temperature maintenance.

Depending upon the tracer used tubing bundles can be cut to length as required or provided with factory installed process and electrical connections.

O'Brien tubing bundles provide the most economical and dependable solution for permanent installations. O'Brien tubing bundles can also be used to provide a heated flexible hook-up between moving parts of machinery or for product dispensing and unloading. Flexible applications with factory finished ends are often referred to as heated hose.

Whatever your application O'Brien Corporation has the technical solution to meet your needs.

TRACEPAK
Your Complete Package for Process Lines
Pvsc.jpg (4952 bytes) TRACEPAK pre-engineered, pre-insulated systems control freezing, dew point, component drop-out and viscosity in small diameter process lines. TRACEPAK not only saves money and time during the installation process, it also ensures consistent, repeatable performance for your process.

The TRACEPAK total package (tubing, heater, insulation and jacket) replaces costly field tracing and insulating with a permanent solution. With TRACEPAK, your installation times are reduced, and you'll see a lower installed cost. Take a look at the chart below for even more benefits of using TRACEPAK.

Feature

Benefit

Description
Parallel Construction Easy installation which takes less time TRACEPAK's unique parallel construction simplifies field installation, because tubing is not cabled or twisted, allowing for easier, tighter bends and connections.
With O'Brien TRACEPAK there is no need to un-cable tubes and then apply field insulation.
Tubing stays round, providing easy connections. Process and tracer tubes are not twisted together (Cabled) they are kept parallel. With O'Brien's unique construction all the tubes bend together during installation. All the tubes also remain round, making the installation of compression fittings easy.
8-inch Bending Radius
Tightest bending radius available.		 TRACEPAK's parallel construction allows the tubes to bend together, side-by-side, so the bundle can bend to an extremely tight, 8"/200mm bending radius.
Disynchronous Insulation Wrap Uniform insulation with no cold spots. Thermal insulation is spiral wrapped over the process tubes and tracer. The insulation is overlapped an each successive layer is applied in the opposite direction. This maintains insulating properties at bends where the insulation in other products may separate leaving gaps. Insulation gaps cause cold spots in the process tube and hot spots in the jacket.
Non-wicking Insulation Prevents moisture from traveling down the entire length of your bundle. Special insulation construction virtually eliminates wicking.
Urethane Jacket Install down to -40fF

Flexible

Long lasting

 Excellent abrasion and chemical resistance combined with a wide, usable temperature range make TRACEPAK durable and workable.The chloride-free urethane jacket stays flexible enough for installation down to -40°F/°C and has a minimum service temperature of -67°F/-58°C.
In-stock Materials Quick delivery to meet your needs. O'Brien's large stock of raw materials offers a choice of many tubing sizes, types, and metallurgy. In addition, we have an abundant supply of finished TRACEPAK -- ready to ship.
Vast array of tubing materials available to meet your needs. Any material that is available in tube form can be fabricated into an O'Brien TRACEPAK bundle. Materials range from dead soft copper to fluoropolymers to stainless steel to zirconium to silica lined steel. Sizes range from 1/8"/3mm to over 1"/25mm.
Halogen Free Eliminate source of halogens that cause stress cracking in stainless steel. Generally referred to as chloride stress cracking, O'Brien has eliminated the major sources of all halogens that promote stress corrosion in stainless steel tubes.

The urethane jacket contains no halogens, halogen free mylar tapes are used for structural bindings, marking inks for tube identification are free of halogens. Even the insulation contains no free chlorides and water soluble chlorides average less than 50 ppm.
Finite Element Analysis Guaranteed performance TRACEPAK tubing configurations are calculated with a Finite Element Analysis tool to ensure maximum performance. The designs are then tested in our environmental chamber to simulate the most extreme conditions and verify performance modeling tools.
Electric Tracers Durable, reliable heating. Self limiting electric tracers are available to withstand 420fF/215fC while tubing bundle designs can handle blowdown temperatures to 1000fF/540fC. TRACEPAK is approved for use in hazardous areas by FM, CSA, and BASEEFA.
