FLEXWELL Safety Pipe is a coaxial double-walled,
flexible and endless piping system supplied ex works
coiled on reels. It is designed for permanent leak
monitoring and approved for the transport of water
pollutant, hazardous and flammable products.
It is available in sizes from DN 15 to DN 100 with
pressure ratings up to PN 25.
Leak monitoring
The annular gap between the primary and outer
containment pipes forms a surveillance space which
enables permanent leak monitoring by approved
leak detectors working on the vacuum or positive
pressure principle.
Type approval
FLEXWELL Safety Pipe with leak monitoring is a
recognized leak detection system within German
regulations.
There a leak detection system is defined as all the
equipment necessary for the detection of leaks (the
monitoring space, the leak alarm, double-walled
piping system, leak detection medium)
– Subject to technical modifications –
Legal basis
- environmental legislation and water protection
requirements
- European standards for leak detection systems
- Product is in compliance with all German environmental and water purity legislation as well as

acts in respect of fire and explosion prevention.
The operation of this system complies with the highest European safety level. Systems of this class show
a leak either above or below the fluid surface in
double-walled safety systems. They are constructed
for safety and ensure that no leaking product can
escape into the environment.
Laying and installation

The safe transport of hazardous substances makes
continually growing demands on the constructors
of fuel depots and industrial plants. In order to
optimize the use of FLEXWELL safety piping, which
already offers a high level of safety anyway due to
its double-walled construction, special flanged pipe
connections, elbows, T-pieces and through-connections with monitored gasket seals are available. They
can be integrated into the leak monitoring system
so that permanent, uninterrupted monitoring of the
entire pipe system from the tank to the user becomes possible.
These double-walled and monitored fittings must be
located where they are clearly visible. It is not permitted to install flanged fittings below ground.
The principle of monitoring gasket seals consists in
having a radial groove extending full circle over the
sealing surface of the flanged fitting that connects
via a drilled port hole to the surveillance space of the
safety pipe.
The complete system comprises the double-walled,
flexible FLEXWELL Safety Pipe, the monitored pipe
fittings and the leak monitoring system.
Due to the flexibility of the pipe, the use of elbow
fittings is unnecessary within certain bending radii,
and the entire pipe length can be laid in one piece.

Leak Detection Systems
LDS
Leak detection
for FLEXWELL safety pipe
3.401
System description
07.04
Leak monitoring
FLEXWELL safety piping is permanently monitored
using pneumatic leak detection equipment/ leak
detectors. These regulate the monitoring pressure in
the surveillance space and register any changes of
pressure which may occur.
The surveillance space is filled with the leak detection
medium (an inert gas) and prevents uncontrolled
spillages of the transported product when leaks
occur. The surveillance space must be so constructed
that the functioning and operative security of the
leak detection system (the leak detector) is assured
at all times when the leak monitoring system is
connected.
If the pipe is damaged the alarm is emitted by acoustic and optical signals.
Definition of leak detection equipment/
leak detector
“Leak detection equipment/leak detector” according
to the currently valid regulations refers to a device
which automatically and under all operating conditions gives warning of leaks in the walls of doublewalled piping in which water hazardous, (flammable
and non-flammable) fluids are transported.
The main components are:
the leak detector/leak detection equipment (LAZ)
the connection between the surveillance space (UR)
and leak detector (LAZ)
double-walled piping
the surveillance space (UR)
a leak detection medium
The use of this system complies with the most stringent European safety standards (Class 1). Systems
of this class give warning of a leak above or below
the fluid level in a double-walled protective system.
They are constructed on the principles of absolute
safety and ensure that spillages of products into the
environment cannot occur.
Leak detection equipment/leak detector (LAZ)
We distinguish two types of differential pressure leak
detection equipment:
Leak surveillance to detect leaks in double-walled
piping on the vacuum principle and on the positive
pressure principle (using an inert gas)
FLEXWELL Safety Pipe with a vacuum leak detector.
FLEXWELL Safety Pipe with a positive-pressure leak
detector.

Leak detection systems on the vacuum principle
Leak detector on the vacuum principle are suitable
for monitoring FLEXWELL Safety Pipes for the transport of:
- water-hazardous, flammable substances
- water-hazardous, flammable substances
<=55°C only in the Ex-variant
- water-hazardous, non-flammable substances
In every case in which the alarm is triggered, the
vacuum pump is automatically switched off. It can
only be switched on again by throwing the toggle
switch mounted on the outside of the leak detector
for this purpose.
Technical basis
The scope of application of the leak detection device
must be limited to fixed maximum pipe lengths due
to the laws of physics. These depend on the diameter of the FLEXWELL safety pipe used and the type
of laying. The methods of laying can be seen from
the worksheets and approval documentation.
Installation/Commencement of operations/
Operation/Function testing
Detailed descriptions can be seen from the approval
documentation of the leak detectors and the worksheets for FLEXWELL safety piping.
The conditions set out in the approval for FLEXWELL
safety piping and the leak detectors used must be
complied with.
Principles of functioning
The vacuum pump installed in the leak detector creates a partial vacuum.
By monitoring this partial vacuum, leaks in the walls
of the piping are automatically detected.
In the event of a drop in the partial vacuum (a rise in
pressure) due to a leak below the lower value of the
monitoring level of partial vacuum, the optical and
acoustic alarm is triggered.
Minimal, unavoidable permeability (not leaks) are
regulated automatically by the leak detector, without
triggering the alarm if they lie between the upper
and lower values of the monitoring partial vacuum.
Subsequent evacuation is carried out by the vacuum
pump in the leak detector.
It therefore goes without saying that the conditions
for operative use have been tested by the competent
authorities and clearly defined and set down in the
documents of approval issued by them.
FLEXWELL safety pipe with leak monitoring is an
approved leak detection equipment/leak detector
system.

Approval/suitability
All leak detection equipment/leak detectors in use
must comply with the basic criteria laid down for
construction and testing standards. All such preconditions which could have a bearing on the functional
and operative safety of the system must therefore be
observed.

Safety Pipes for the transport of :
- water hazardous flammable substances
- water hazardous non-flammable substances
Principles of functioning
The necessary pressure in the surveillance space of
the FLEXWELL safety pipe depends on the actual
operating pressure in the medium pipe (inner pipe)
and is generated:
- by topping up, regulated by pressure changes,
from a stationary nitrogen pressure reservoir
which is constantly connected with the surveillance space

- from a mobile pressure reservoir which is only
connected when the line is put into operation or
during a function test.
Operating mode M
– Subject to technical modifications –
The surveillance space is connected with the leak
detector by means of the connecting leads. The pressure which builds up is measured by the pressure
sensor. If pressure drops to the value set previously
for ALARM ON due to a leak, the optical and acoustic alarm will be triggered.
In stationary operating mode the monitoring pressure is regulated after putting the system into operation by pressure changes which top up from a
stationary nitrogen pressure reservoir which is constantly connected with the surveillance space and
equipped with a pressure reducing valve.
In mobile operating mode the monitoring pressure
(TOP-UP OFF) is set just once when the system is put
into operation by a pressure reservoir which is not
constantly connected.

The sealing element consists of a cross linked polyolefin heat-shrink sleeve, buttressed internally by a
galvanized steel spiral. The outside of the convoluted
surface has a special coating, which forms a longitudinally watertight bond with wet concrete or mortar.
Both ends are coated inside with a plastic sealing
compound. When heated using a gas flame the
ends shrink and the sealing compound melts and is
pressed into any grooves or irregularities.

Wall entry seals type MD for FSR 83/120 and FSR 127/175
The sealing element consists of a cast iron sleeve, a
sealing ring and a collar flange. The sleeve is fitted
with radial grooves which effect the longitudinal
water tightness in the concrete or mortar in similar
fashion to a labyrinth gland. The FLEXWELL Safety Pipe is sealed with a sealing packing, which is
pressed into the sleeve upon tightening of the bolts
of the collar flange.

General note:
The steel manhole and jacket pipe wall entries Type
SSE for FLEXWELL Safety Pipe are designed to fit
sleeves made from standard steel pipe. For standard
sizes refer to table below. The pipe sleeves must be
supplied, set and sealed into the steel manhole or
masonry wall by the client.
Warning !
If FLEXWELL Safety Pipe connecting joints are to be
fitted later, use split collar flanges. Standard collar
flanges are larger in diameter than the pipe sleeves
and won’t fit.
