Pipeline repair in a potash mine

When I visited a potash mine, I noticed this "cemetery"
of used pipe parts for the hydraulic potash extraction.
There are around 200 pipe parts of different diameters,
lengths, angles and radius. All parts that were specially
manufactured for this production. The pipe parts are all
lined with cast basalt and have a 3-component
anti-corrosion coating. On average, these new pipe parts
cost EUR 700.00 / piece. So there is a value of at least
EUR 140,000.00. Since the pipe parts show more or less
wear damage, all should be disposed of. The disposal
costs amount to at least EUR 12,000.00. The new price
for the pipe is approx. 156,000.00 EUR and the delivery
time is at least 3-4 months.

I explained to the plant management that we can repair
all the pipe parts. We would remove the existing and
partially worn cast basalt lining and replace it with a
new UHPC wear protection lining. I calculated the
budget costs for this at EUR 66,000.00. The repair work
takes approximately 2 months. Here, however, we could
orient ourselves according to the wishes regarding the
installation sequence to the customer and always repair
the pipe parts that he needs at short notice.

Our customer decided on a new lining instead of a new
production and saved 90,000.00 EUR and at least 1-2
months delivery time.

Today there are no more "cemeteries" for used pipeline
parts in his plants.

UHPC Security projects in south of Europe

Two new UHPC security projects are
scheduled for the coming year. Both
projects are to be carried out in Europe.



The first project is a concept for securing
private property. In a former mine in the
Alps, securing rooms of the highest security
class are to be installed in former tunnels
on different levels of this mine. In order to
maintain this safety class by insurance
companies, investors have specified the
extension of the tunnels and individual
rooms using UHPC concrete.
In the first stage, about 8000 tons are to
beinstalled.



The second project also applies to the
protection of private property. In this
concept, a former military nuclear bunker
is being rebuilt. Again, most of the new
structural alterations are planned with
UHPC.
For both projects, UHPC concrete is just
one part of the backup work. We have
developed a new UHPC material quality
for both projects, which can be optimally
processed in very large quantities in both
very different locations.
