UHPC lined hydraulic conveyor pipelines for brine in salt mines

More than 14 years ago, a high-pressure-safe

(loadable up to max. 100 bar / 1450 psi) brine

hydraulic transport pipeline with UHPC wear

protection was installed as a test for other lines.

The pipe installation took place underground. In

addition to the extreme pressure, the line

should be highly wear-resistant and highly

corrosion-resistant.

After all these years, we had the opportunity

to check this line together with the customer

on site.

A pipe element was also removed from the

line and cut open to inspect the UHPC lining.

Neither the customer nor we expected such an

extremely good result after all these years of

operation.

The UHPC lining has only lost a few

millimeters from its 30 mm lining.

Thanks to the seamless, waterproof UHPC

lining, no expensive corrosion protection was

necessary during wear protection assembly.

Which made assembly much faster and less

expensive than the linings previously used.

Past and future of concrete in security and military

In the past there have always been interesting

safety solutions with concrete.

Some were successful, some were not. A

success story were bunker structures

underground or above ground for the navy, air

force and army. Even today, concepts for

military and civil security rooms are carried

out with concrete structures.

The next generation in which concrete is

replaced by Ultra High Performance

concrete, or UHPC for short, has been used

very successfully worldwide for a few years.

These UHPC security concepts resist the

strongest attacks, penetration is almost

impossible with the current known weapons.

UHPC security concepts are also increasingly

used in the civil construction industry for

security constructions in safes and security

rooms, coastal protection, fire protection, storm

protection, disaster protection and terrorism

protection.

We are constantly developing UHPC for new

applications, such as floating, unsinkable

platforms that can be used anywhere in the

world, both civil and military.

UHPC Phalt a semi rigid top layer for all areas of an airport

Our nanotechnology for UHPC binder is now

over 30 years old and has been used in a wide

variety of areas worldwide.

From the beginning, the idea was to create a

material combination that combines the best

material properties of both products in an ideal

and flexible manner.

We call this combination material UHPC-Phalt.

The technique is simply, lay a coarse-grained,

porous, locally produced standard asphalt and fill

the pores with an extremely liquid UHPC concrete.

The result is that a flexible, temperature-resistant, 

high-pressure-resistant and extremely resilient, 

frost and de-icing salt-resistant, long-lasting

runway surface is created.

Benefit:

High axle loads, extreme ambient temperatures,

limited construction time and

constrained budgeting.

Standard laying machines and mixing machines

can be used for processing. Asphalt assembly

companies can easily lay this combination of

such materials

Local asphalt qualities can easily be used for

processing.

Fine sand or desert sand can be used for the

UHPC concrete.

Our UHPC binder can be flexibly adapted to

customer requirements. Curing speeds can be

adapted to customer requirements so that the

laying speeds of the laying machines can be

used to the maximum.

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.
