Our customers are frequently amazed by the exceptional capabilities of Thermoflex. We thought we’d take this opportunity to systematically answer questions and clear up some basic misunderstandings.

 

How long does Thermoflex pipe last?

Standard service life is 20 years or longer, depending on specific operating conditions.

 

Can Thermoflex take the pressure?

Au contraire. One- to 6-inch Thermoflex composite pipe can actually accommodate up to 1500 psi.

 

Can Thermoflex handle volume?

With a lower friction coefficient than steel, Thermoflex composite pipe delivers greater flow with a smaller diameter. Our engineers will happily provide pressure-drop and flow calculations upon request.

 

Has Thermoflex ever failed?

With over 5,000 of miles of Thermoflex installed, there has never, EVER been a catastrophic in-field failure associated with a Polyflow pipe or fitting. If an issue ever occurs, our technicians are on call 24/7.

 

How long does installation take?

Thermoflex is lightweight, flexible, and comes spooled in long, easily connected lengths. This adds up to quick and headache-free field installation. Depending on application, it takes a fraction of the time required for steel installations.

 

Does Polyflow hydro test?

We do and it’s certified. Standard hydro test is at 1.25 X the maximum operating pressure (MOP) for eight hours. For DOT and hazardous material lines, testing I at 1.5 X MOP.

 

Can you tap into the main for future lines?

Yes, you can cut into any original line—regardless of its years of service—and install a fitting that can accommodate new or future lines.

 

Can you connect Thermoflex to steel or HDPE?

Of course. We have numerous fittings that allow for transitions to steel pipe, HDPE pipe, or other components.

 

Do I pay for the reel?

Nope. We ship it and—provided your contractor breaks it down—we pick it up. If you keep it longer than 90 days however, there is a rental charge.

 

Is installing the connections time-consuming?

No, unless you consider 6-10 minutes per fitting to be time-consuming. It’s a quick, one-step process with a portable swaging machine.

 

Is the swaging procedure difficult?

Not at all. No crane is necessary and the equipment can be operated by 1-2 people.

 

Can Thermoflex be above ground?

Thermoflex—which is UV protection—can lay on the surface if the pressure doesn’t exceed 750 psi. Any pressure over that will require burial.

 

Can I use my own team to install Thermoflex?

Sure. We will provide certification and training for operators and contractors—and we’re happy to hang around and oversee the installation.

 

Must a Polyflow technician be on-site during installation?

No. As long as you have a certified operator or contractor installing the pipe, we don’t have to be there.

 

What about pressure surges?

Bring them on. With an aramid-fiber liner for reinforcement, Thermoflex is engineered for excellent stability during cyclical loads.

 

Does Thermoflex require derating for hydrocarbon service?

No. It’s build to withstand the higher pressures and temperatures associated with upstream and midstream applications without derating, permeation, or reduction of capacity.

 

Can Thermoflex pipe be pigged?

Yes. Our fittings happen to be the same outside diameter as the pipe, which makes pigging smooth and efficient.

 

Can Thermoflex be hot-oiled?

Yes, we provide hot oiling as an optional service to further reduce internal friction and minimize the potential of paraffin buildup.
