Globe Contributes to Sprinkler Age Magazine

Globe's John Desrosier, a new technology research engineer, contributed the article "Temperature Change and Dry Pipe Systems Fluctuations Can Cause Problems" in Sprinkler Age Magazine.


"As fire protection designers and engineers, we tend to think of sprinkler systems as very static systems. Hydrant flow tests are run and sprinkler designers design the system around the expected pressures. In actuality, sprinkler systems tend to be expanding and contracting, pressurizing and depressurizing, heating and cooling, in cyclical periods. Most of the time the pressure increases are not significant enough to cause problems but occasionally the perfect storm arises and several installed conditions and atmospheric conditions come together and can cause “the valve to trip on its own.” Both of the aforementioned conditions can be combated by the introduction of a relief valve. It is now required on all wet systems to include a relief valve, but I would recommend a relief valve on the water side of any direct differential style valves. The fairly inexpensive valve has the potential to prevent some false activations, which can save trips to a site and the headaches associated with false activations."


About Globe Fire Sprinkler


Globe Fire Sprinkler is a family owned fire sprinkler manufacturer, headquartered in Michigan. We celebrated 100 years of continuous production of Globe Sprinklers and Valves in 2014; the Globe name has persisted in its enduring identity since the introduction of the first Globe Issue "A" Sprinkler in 1914. Globe developed the earliest lever-fulcrum dry pipe valve, Globe Save All center strut sprinklers, and eventually became the first US company to utilize 5mm and 3mm Glass Bulbs in its commercial and residential sprinklers. Its modern era began in 1988 with the guidance and dedication of Golden Sprinkler Award recipient Robert Worthington, P.E. until his passing in 2016. The Worthington family continues to own and operate Globe, under the leadership of Steven Worthington and a team of some of the industry's most seasoned professionals. Globe's heritage as a leading sprinkler manufacturer is reflected in the introductions of the RCW, UM, UMC valves, and other new products the company develops to meet the demands of the world market. The company proudly maintains strong relationships with approval authorities including Underwriters Laboratories Inc, FM Approvals and the Loss Prevention Certification Board (UK). Globe has the LPCB (UK) certification for ISO 9001:2015 series Quality Assurance, therefore exhibiting proof of the quality it continuously builds into each of its 100% factory-tested products.
