SYSTEM DESCRIPTION

FLEXWELL® Safety Pipe was specially

designed for the underground transpor

t

of flammable, water-hazardous fluids

.

It can be used as a suction or positive

pressure supply pipe. The FLEXWELL®

Safety Pipe can be permanently moni

-

tored by means of suitable leak detec-

tors.

CONSTRUCTIO

N

FLEXWELL® Safety Pipe is a flexible,

permanently monitorable, double-walled

pipe system. The FLEXWELL® Safety

Pipe consists of a corrugated stainles

s

steel inner medium pipe, a reinforcin

g

band and a corrugated outer contain-

ment pipe made of stainless steel. The

annular gap between the inner and out-

er pipes is a surveillance space for leak

monitoring. External corrosion protec-

tion is provided by a PE casing coverin

g

the outer pipe

.

NOMINAL BORES /

PRESSURE STAGE

S

FLEXWELL® Safety Pipe is available in

nominal bores from DN 12 to DN 150.

It can be operated with positive pressur

e

up to max. 25 bar.

LAYING THE PIPE

S

FLEXWELL® Safety Pipe can be laid

directly into the trench in one piece. It

can be laid either overground in a trac

e

or inside of bulidings. The unique corru-

gated pipe geometry of inner medium

pipe and outer containment pipe ensures

excellent flexibility. It can be cut to the

required length at the construction site,

laid ”endlessly“ and bent through tight

radii thanks to its flexibility.

Monitorable through-connections an

d

T-pieces as well as connectors with

LEAK MONITORIN

G

The surveillance space between the in-

ner and outer pipes can be permanently

or negative pressure leak detectors.

A

wide range of leak detection systems fo

r

different areas of application and lega

l

requirements is available.
