Heat tracing can protect sections of pipe in wet fire sprinklers from freezing, providing a viable alternative to installing or retrofitting more complex and expensive dry pipe or preaction systems. QRFS explains various types of heat tape, including NFPA standards, cost, and maintenance requirements.
The additional components required in dry fire sprinkler systems compared to wet systems can make installation more challenging. QRFS helps you understand NFPA 13 requirements for installing dry pipe and check valves, as well as quick-opening and antiflooding devices.
Closing or opening a valve can cause a sudden surge in pressure, threatening water-based systems and the people who work around them. QRFS explains the phenomenon known as water hammer, describing what is, how it works, and how it impacts firefighting and the design of fire protection systems.
A look at the evolution and impact of fire safety code that has caused most new commercial buildings to have fire sprinklers – and how revised code and local governments are now driving sprinkler retrofits in existing buildings.
With additional control equipment and air pressurization devices not found in wet sprinkler systems, installing a dry sprinkler system ups the complexity factor. QRFS explains components and NFPA requirements for installing dry systems in areas prone to freezing.
NFPA 13: Standard for the Installation of Sprinkler Systems has guided insurers, installers, and designers for more than a century. QRFS looks at the National Fire Protection Association's 2019 changes, exploring technical revisions impacting ESFR storage sprinklers, system components, and sprinkler system design.
Collisions with sprinkler heads can cause costly flooding — but standard fire sprinkler cages may not be strong enough to withstand the hits some sprinklers are likely to face. QRFS looks at a line of heavy-duty fire sprinkler head guards designed to address the vulnerabilities in high-impact environments.
As the 2022 deadline for phasing out all current antifreeze solutions in wet sprinkler systems looms, the first – and only – product to meet the National Fire Protection Association’s (NFPA) standard is good news for property owners in regions that suffer bitter winters. QRFS reveals why current solutions were deemed unsafe and details the new solution.
Wet sprinkler systems may dominate the fire safety market, but there’s a better solution for certain environments prone to freezing: dry sprinkler systems. QRFS explains how dry systems work, providing the coverage you need without the fear of burst pipes.
