Knowledge of rated bends, manufacturers, and fire code can help contractors make informed decisions about the selection and installation of flexible fire sprinkler drops. To learn more about FlexHead, VicFlex, and other leading products, read on.
QRFS looks at the adoption of flexible fire sprinkler drops, explaining how they work with suspended ceilings, why they install faster than sprinkler armovers, and how they help installers protect sprinkler systems against earthquakes.
Learn about pipe joint lubricant: what it does, when it’s used, safety issues, and how lubricants vary across leading brands such as Phoenix 27 XL, Phoenix 27 A, and ProSelect.
CPVC pipe offers a quick and easy way to install fire sprinkler systems in light-hazard applications, without the expense or hassle of using metal. To implement a successful design, installers have to be aware of compatible chemicals and uses, product care, and listed uses.
A comparison of the features and benefits of Sammy Screws and DeWALT HangerMate+ fasteners used for hanging pipe in fire sprinkler systems and other 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.
Contractors of all kinds rely on concrete anchors, but these fasteners’ impressive grip can make them particularly tricky to remove. QRFS takes a look at established and emerging ways to quickly remove concrete anchors.
PEX tube has been approved for use in wet fire sprinklers, in both multipurpose and standalone systems — but can PEX be used in dry or preaction systems? QRFS answers a question posed by a reader — and gets a ruling directly from the National Fire Protection Association (NFPA).
CPVC and PEX have become extremely popular, safety-approved pipe materials in home fire sprinkler systems. Both are easier and less expensive to install than metallic pipe and have better performance characteristics. But which of the two thermoplastics is better? QRFS attempts to answer this excellent question.
In this article, we dive deep into the world of fasteners. You’ll get a better understanding of what they are and how to use them, look at the guidelines provided by the NFPA, and explore available options.
