Prérequis
Every king of education on material, material properties, water solution chemistry
Objectif
Learning some basics on corrosion processes and scaling processes in HVAC water networ in buildings.
Identifying the main case histories and their origine.
How to treat water/system to reduce or limit scaling and corrosion.
What are the standards and the best practices and state of the art.
Programme
Parameter to be measured on water to evaluate corrosion issues or scaling issues (water chemistry, titration, units, precision ...)
Electrochemistry of corrosion processes (galvanic cells, differential aeration cells, stress/fatigue corrosion, crevice/pitting corrosion ..)
But also physical deterioration i.e. erosion corrosion, cavitation ... and microbial corrosion (biocorrosion)
Description of the different material used in plumbing/piping. Mechanical properties/ metallurgical structure/forming processes in connection with corrosion
Standards and best practices (DTU, NF, EN ...)
Treatment and prevention.
Scope :
drinking/tap water, hot (sanitary) water, heating system (high temperature/low temperature), underfloor heating, cooling system (with or without glycol), steam system (open/closed or semi-closed system)
