What causes pinhole leaks in fire sprinkler systems?

Internal corrosion can block or reduce the flow of water in the system and may lead to loss of life and property. In dry systems a pinhole leak releases compressed air, causing the auxiliary air compressor to run continually to try to keep up the air pressure in the system. How do I protect my Fire Sprinkler System from corrosion damage?

What are the NFPA requirements for dry pipe sprinkler system?

In this installment of our series on dry sprinkler systems, we examine the National Fire Protection Association (NFPA) requirements and best practices for dry pipe sprinkler system trip tests, as well as for performing an associated test on main drains. Are you looking to buy components for your building’s sprinkler system?

What to do if your fire sprinkler system leaks?

Even if your fire sprinkler pipes look perfectly fine on the outside, corrosion could be actively compromising the inside of your pipes. The next time your fire sprinkler system is serviced, ask for a corrosion analysis and water test.

What happens if a dry pipe sprinkler system trip?

If it remains stubbornly closed when sprinkler heads are activated, the water supply will never reach the fire, rendering the sprinkler system useless. And if it trips improperly, a property could face water damage. This is why dry pipe sprinkler system trip tests are crucial.

How does a dry pipe fire sprinkler system work?

Dry Pipe Fire Sprinkler System A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. This air holds a remote valve, known as a dry pipe valve, in a closed position.

Can a dry pipe sprinkler system cause corrosion?

Increased corrosion potential – Following operation, dry-pipe sprinkler systems must be completely drained and dried. Otherwise remaining water may cause pipe corrosion and premature failure. This is not a problem with wet pipe systems where water is constantly maintained in piping.
