摘要： Fire protection sprinkler assemblies and methods of use in corrosive environments. The sprinkler assemblies include a corrosion resistant sprinkler frame made of a gradient material. The gradient material includes a polymeric layer interlocked about a corrosion-prone core in order to protect the frame structure from a corrosive environment. The interlock between the core and the protective polymer layers are defined by ionic bonding between the core and the outer polymer layer.

摘要： System and methods using automatic fire protection sprinklers to provide ceiling-only fire protection of rack storage. The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote fire protection sprinklers with a prescribed hybrid minimum design pressure.

摘要： Fire protection systems and methods provide for the protection of horizontal concealed interstitial spaces of either a solid wood joist, open bar joist or open truss construction system. The systems and methods provide and locate fire protection sprinklers to define localized heat detection areas that are over 1000 sq. ft, at least 2000 sq. ft., over 2000 sq. ft. and/or otherwise unconfined by draft curtains or other barriers.

摘要： System and methods to provide ceiling-only suppression fire protection of up to fifty feet (50 ft.) of rack storage of cartoned unexpanded plastic commodities and less hazardous commodities, such as for example, Class 1, Class 2, Class 3, Class 4 and/or combinations thereof beneath a ceiling having a maximum ceiling height up to fifty-five feet (55 ft.). The systems and methods provide for hydraulic and system parameters that include a hydraulic design area based upon five to no more than twelve hydraulically most remote sprinklers spaced at a preferred sprinkler-to-sprinkler spacing of eight to ten feet (8-10 ft.) coupled to two to four branch lines tied to a common cross main supply pipe of firefighting fluid.
