HomeMy WebLinkAboutFlexwellFlexible, double-wall corrugated pipe system with continuous
interstice for leak detection
General description
The FLEXWELL®-HL pipe system is specifically designed for hazardous
fluids and gases, such as gasoline, ethanol blends, biodiesel, LPG
and other hazardous fluids typically transported in chemical plants.
The pipe is used in gas stations underground as well in above ground
applications such as marinas and bulk facilities. FLEXWELL®-HL can
be operated as a suction or pressure system and can be continuously
monitored via suitable and approved leak detection systems.
Construction
Applications*
• Suction pipes
• Pressure pipes
• Fill pipes
* Subject to compliance with local and national regulations
Sizes and pressure ratings
FLEXWELL®-HL is available with an ID of 1" (ND 25) to 3" (ND 80) for
conventional use at an operating pressure of up to 145 PSIG (10 bar)
and temperatures between – 50 °C (– 58 °F) to + 50 °C (+122 °F). For
FLEXWELL®-HL
Double Wall Stainless Steel Pipe for Above Ground, Below Ground,
Marina and Commercial Fuel Systems
Installation
FLEXWELL®-HL is manufactured in factory lengths up to 3,000 ft.
FLEXWELL®-HL can be laid directly into a trench in one piece following
any directions without necessity of intermediate joints or fittings. The
corrugated design of the primary and secondary pipes assure excellent
impact resistance while at the same time providing a high degree of
flexibility.
Leak detection
The interstital space between the primary and secondary pipes is
designed for leak detection via either pressure or vacuum, depending
on local regulations or operating requirements.

FLEXWELL®-HL is a flexible pipe system made of corrugated 316lL
(1.4404) stainless steel primary and secondary pipes for operating
pressures of up to 145 PSIG (10 bar). The interstitial space between
primary and secondary pipe can be used for leak detection. The pipe is
corrosion protected by a polyethylene jacket. The stainless steel pipe
provides an enduring, impermeable barrier, even with future new fuels
or fuel combinations.
gases such as LPG, FLEXWELL-LPG single-walled pipe can be operated
at up to 360 PSIG (25 bar).
