Three decades ago, corrosion at a fire sprinkler system was thought not to even exist, and failures were exceptionally rare. Investigations of 80 year old fire systems defined them in still near new condition. Yet today, their failure is a major source of building interruption.
The transition from schedule 40 toward thinwall schedule 10 and schedule 7 pipe, exceptionally poor quality galvanized steel, undersized pipe, ERW seamed pipe, low cost foreign products - all represent just some of the causes leading to advanced failure.
Add to that list the growth of "dry" and pre-action fire protection systems having substantially greater corrosion losses.
We provide below a series of Technical Bulletins related specifically to fire protection systems. All are directly based upon our 38+ years of experience in this field, and offer either an explanation or potential solution to common everyday problems and concerns.
