As sprinkler systems become more common, the fire protection industry has attracted unscrupulous manufacturers and sellers of counterfeit fire sprinklers. Learn how to ID real and fake fire sprinklers, as well as where to look for counterfeit advisories.
A wide range of standards govern the construction and use of valves—so, can angle valves designed for one purpose be used for another? QRFS looks at angle valves in fire protection, HVAC, plumbing, and beyond, discussing their construction, manufacturing standards, and suitability for various applications.
Fire sprinkler installers looking to compete in the home fire sprinkler market have a wide variety of piping materials at their disposal. QRFS estimates the prevalence of piping materials, including PEX and CPVC fire sprinkler pipe, and explains how some factors—namely, cost—have left copper and steel with a much smaller role.
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.
Increasingly complex industrial facilities need advanced fire protection and life safety systems. QRFS reviews NFPA and ICC requirements for an industrial occupancy.
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.
