BOA VENTINOX HR
Chimney liner for low temperature heating installations,
perfectly tight, welded The VENTINOX-HR hose is a highly
corrosion resistant, flexible chimney liner, perfectly appropriate
for heating installations running under low temperature conditions.
The VENTINOX-HR liner has the right characteristics for applications
working at temperatures below the acid dew point. With a global
index of 41* the material used is a high-alloy steel (frequently used
stainless steels have a global index less than 30). Thus the
VENTINOX-HR is extremely resistant
Material:
corrugated hose: stainless steel F29-M, AL 29-4C
wall thickness: 0,2 mm
against different types of corrosion, particularly against pitting corrosion, the most common corrosion type present in low temperature heating installations. A higher percentage of chrome and molybdenum is responsible for such excellent physical performance. It may be used at higher temperatures up to 450°C. *The global index is an empirical value which states that the risk of pitting corrosion diminishes when its value is >30.
