FLEXWELL® Safety Pipe –

innovative and proven in many

applications

Safety through double-walled

construction

The surveillance space between the

inner and outer pipes enables per-

manent leak monitoring using ap-

proved leak detection devices oper-

ating either on the positive pressure

or vacuum principle. The use of

these systems is compliant with the

highest European safety standards.

The system is constructed with safe-

ty in mind and will detect any leak

above or below the fluid level within

a double-walled protective system.

Safety through permanent

monitoring and remote diagnostic

systems

The leak detector online diagnosis

(LOD) system enables safe and on-

going remote monitoring of a leak

detection device. All operating para-

meters are recorded around the

clock, automatically transmitted to

the LOD server and analyzed there.

Any irregularities which may be de-

tected in the leak detection system

can already be recognized in this

way even before the annual mainte-

nance check is due and can there-

fore be pinpointed more easily and

fixed, thus reducing costs.

When an alarm is given, all relevant

stakeholders are informed by text

message and/or email.

General type approval:

Z-38.4-253

Universal connection fittings

The use of FLEXWELL® Safety Pipe

is designed for the transport of very

diverse media. The demands placed

by these require connection fittings

which are just as reliably tested

and certified. With the GRAPA®-

modular system it is possible to offer

a comprehensive range of different

connections, all based on identical

principles and workmanship.

In the course of technical mod-

ernization and development, the

following joining techniques for the

connections have proved to be the

best:

A graphite with cutting ring

(non-welded)

B graphite with soldered end

C graphite with rubber seal

(non-welded)

D TIG welding/hard-soldering
