In all areas of chemical engineering,
the amount of maintenance required
is comparatively high. This
particularly affects equipment for
the conversion, treatment,
transportation or storage of media,
such as autoclaves, filters, vessels,
tanks, sieves, heat exchangers, and
pipelines. In addition, buildings need
to be maintained.
To solve these often very complex
problems, high-pressure water jets
are used more and more.
High-pressure water jetting is a
technique for a large variety of
applications.
The WOMA high-pressure water jet
systems are suitable for the following
tasks:
|
 |
Surface cleaning. |
|
Removal of coatings and paint from buildings, strucutres and technical equipment. |
|
Derusting of steel surfaces. |
|
Cutting and seperating of materials and composites. |
|
Removal of tenacious residues and incrustations from autoclaves, vessels, heat exchangers, pipelines, etc. |
|
Rubber removal from pipelines and vessels. |
|
Partial demolition of buildings and equipment. |
|
The transportation of critical media
represents another permanent
problem in chemical engineering.
Here, WOMA offers special pumps
for the transport of highly viscous
and pasty media, abrasive media
with different solids loading, and
chemically aggressive media.

Why High-Pressure Water Jets? |
|
There is a wide range of tools available. |
|
Small reaction forces. Therefore, the technique can easily be mechanized and automatized. |
|
No gas, vapour or slag formation. |
|
Minimum vibrations. |
|
High efficiency. |
|
Very careful removal of coatings, dirt and contaminations. |
|
High degree of industrial safety. |
|
Exclusion of chemical agents. |
|
Small tool dimensions and low weight. |
|
No influencing of surface structure or mechanical properties of the parts and materials treated. |
Range of Materials |
|
Using high-pressure water jets, the
following materials can reliably and
efficiently be removed:
adhering multi-layered coatings,
contaminants, dirt, cakes and
incrustations, linings, lacquer
systems, tenacious residues, worn
protective coatings.
Using abrasive ultra-high pressure
water jets, the following materials
can reliably and efficiently be cut:
ceramics, construction steels, fibrereinforced
materials, multi-layered
constructions, pipeline elements,
reinforced concrete.

The Technique |
|
WOMA offers the complete range of
the high-pressure water jet technique.
WOMA’s horizontal plunger pumps,
equipped with central valve heads,
generate water pressures up to 3,000
bar and deliver water flow rates up to
1,679 l/min. The performace range of
the process pumps covers operating
pressures up to 1,000 bar and flow
rates between 17 l/min and 5,000 l/
min.
For complex maintenance
problems, WOMA has developed
complete ultra-high pressure systems
as well as compact hot water jetting
Ecotherm®-Systems. Compact tube
bundle and pipe cleaning units and
vessel cleaning systems are also
available.

programme for application in chemical
engineering comprises the following
tools:
|
|
FlexLanceMaster® for hand-held tube bundle cleaning. |
