2. What is CORROPIPE®?
CORROPIPE® CEM 40 A is a 2-component, solvent-free mineral coating
system which sets hydraulically. The processing mixture is created by the
Product combination of carefully sourced natural minerals and a high-quality reactive
liquid component.
CORROPIPE® was developed in 2001 by Manfred Förster, our chief
History developer, to protect steel surfaces from corrosion.
Its effectiveness and longevity as mineral corrosion protection have been
References tested and confirmed by numerous independent German and international
reports.

3. Problems in wastewater industry
Hydrogen sulphide (H2S) / anaerobic environment / biogenic
sulphuric acid / condensate water / bacteria etc.
Extremely severe corrosion on installations and in pipelines
1. Extremely severe corrosion in pressure
pipelines
2. Weakening of the building construction
3. Production stop, pollution of the environment
and high costs

4. 7 reasons for CORROPIPE® as a solution
1. High resistance to acids and bases from pH 3 to pH 14
2. Temperature stability to 95 C in humidity range
3. For use on workable rust
4. No infiltration by rust
5. Active corrosion protection effect through high pH-value
6. Mineral, solvent-free and environmentally friendly

7. Preparatory cleaning for CORROPIPE®
The steel surface must be free from oil, grease, paints, coatings and all loose
substances when viewed without magnification. Mill scale and/or peeling skin
must be removed by sandblasting. Workable rust can remain. Low residual
moisture (no free water) can be tolerated.
Cleaning can be effected using maximum pressure water or alternatively by
sandblasting.
Quality assurance is checked by an adhesive tensile strength test before the
application of the CORROPIPE® coating.
Pipeline cleaning is effected with maximum pressure water 1300 bar to 1500
bar and approx. 100 litres per minute (rotary nozzle cleaning).

8. Application on rusty steel surfaces
The highly-alkaline environment of the CORROPIPE ® mixture triggers a
chemical reaction between the participating components (rust and coating).
This leads to a transformation (passivation) of the rusty steel surface.
The water-soluble, workable rust is adopted by the coating and integrated
within it.
The residual surface is pure steel, which coalesces homogenously and firmly
with the coating.
The alkaline environment of the coating guarantees active corrosion
protection in the border area between steel and coating, which cannot be
infiltrated.
