The client regularly added inhibitors to prevent corrosion. Study shows that even by using chemicals, corrosion still occurs. Iron or rust in the steam will cause further corrosion in the pipe systems and this leads to a shorter lifespan of eqiupment.
A Merus ring was installed at the feed pipe of the boiler. In the first weeks there no change in the use of inhibitors against corrosion
The iron content in the steam and the Blow down pipe was regularly checked. The iron in the steam became less and less, and finally stabilized on a very low level.
Adding inhibitors didn't stop until 6 weeks after installation. This was also the regular production break where service is carried out on the boiler. On visual recorded inspection, it was seen, that most of the surface was now black, coated with saturated iron oxide, only a few red spots of red rust was observed, and it was expected these would disappear too.
After witnessing this result the client decided to stop adding corrosion inhibitors. The steam is still regularly checked for iron.
It is assumed that the lifespan of the system has now also increased dramatically.
