Internal corrosion of dry and preaction fire suppression systems is a growing concern for the fire sprinkler industry. Corrosion in these systems causes failures resulting in property damage, production downtime, and increased maintenance costs. Additionally, corrosion impacts system hydraulics and reduces the efficiency of fire sprinkler system designs. Historically, dry and preaction fire suppression systems have used compressed air as the supervisory gas to pressurize their piping. Compressed air, however, contains both oxygen and moisture causing the system piping to corrode. Nitrogen, acting as a supervisory gas in piping, is a well documented inhibitor of corrosion and has been implemented in industries such as gas and oil, pharmaceutical, and marine transit. This study analyzes the corrosion-inhibiting effects of 98% nitrogen gas when applied to both carbon steel and galvanized steel, in an environment stimulating a dry pipe fire sprinkler system. The weight loss methodology is utilized to examine the effects.
Upon completion of this webinar, participants should be able to:
- Evaluate the life expectancy of a dry pipe or preaction system under supervisory nitrogen conditions vs. compressed air conditions
- Identify the value of using corrosion mitigation in fire sprinkler system design
- Discuss and analyze the use of a nitrogen generator system for dry and preaction systems.

How does a WEBINAR work?
A desktop or laptop computer connected to
the Internet is required. You will be provided
with a link to join in. You will use your
browser (i.e. Safari, Firefox, Mozilla,
etc.) to get connected to the live PowerPoint
presentation and live audio. You can have
many people listening in your office.;
however, only those who register for a
certificate will receive CEU credit. The
audio will be transmitted though your computer
speakers. Or, you can call in (long distance
charges of about $18 will be posted to
your phone bill.) You can ask questions
from wherever you are using a feature that
allows you to type in your question during
the live presentation. The speaker will
read your question aloud and answer it
live. You will be able to download the
PDF file of the PowerPoint slide presentation
the day of the seminar. You can also print
the PDF file presentation and make as many
copies as you need for note-taking.
