A fire prevention apparatus includes an inner pipe having multiple perforations along a length of the inner pipe. The fire prevention apparatus also includes an outer pipe surrounding the inner pipe, the outer pipe having a slit along a length of the outer pipe. The fire prevention apparatus also includes fire retardant disposed in a gap between the inner pipe and the outer pipe. The outer pipe is configured to compress when a force is applied to the outer pipe, so as to cause the fire retardant to pass through the perforations into the inner pipe.

A method for suppressing a fire including providing a fire suppression system including at least one nozzle within a hazard area, activating the fire suppression system in response to detecting a potential fire within the hazard area, and releasing a fire suppression agent toward the hazard area through the at least one nozzle at a spray angle defined between outermost edges of fire suppression agent when released through the at least one nozzle. The spray angle is a first spray angle for a first time period. The method further including releasing the fire suppression agent toward the hazard area through the at least one nozzle at a second spray angle, greater than the first spray angle, for a second time period.

The present invention relates to a coupling assembly for branching a pipe, and more specifically to a coupling assembly for branching a pipe, which can reduce assembly man-hours, has a simplified configuration, thus enabling a reduction in construction costs, and can effectively prevent the leakage of branched fluid even when the diameter of a branch hole formed in an inlet pipe is increased in order to increase a flow rate inside a branch pipe for supplying fluid to a sprinkler.

The present invention relates to an integrated bracket for fixing a sprinkler reducer, and more particularly, to an integrated bracket for fixing a sprinkler reducer, in which left and right portions of a bar-shaped steel frame structure for a sprinkler bracket are vertically bent, tightening/coupling parts are provided at two opposite ends of the steel frame structure, and a fixing unit having a new structure and serving as a middle bracket is integrated with a central portion of the steel frame structure, such that the single bar-shaped steel frame structure may perform a function of fixing the sprinkler reducer and coupling a ceiling steel frame.

A test, drain and adjustable pressure relief module for a sprinkler system has a single body with three independent and fluidly connectable flow ports. A first port of the three flow ports is fluidly connectable at an inlet side thereof to the sprinkler system. A second port of the three flow ports has an adjustable pressure relief valve removably mounted to an outlet thereof. The valve is biased into a closed position and a threshold pressure is required to open the valve and discharge fluid is selectively adjustable. A third port of the three flow ports has an open outlet end configured to removably connect with a drainage pipe. The three ports form a Tee connection and have a flow valve therebetween to selectively direct flow between an outlet of the first port and at least one of the respective inlets of the second and third ports.

Disclosed is a lockable pipe shield for a pipe support assembly, a pipe support assembly, and a method of securing a lockable pipe shield to a pipe hanger. Example aspects of the lockable pipe shield for a pipe support assembly can comprise a substantially semi-cylindrical shield body defining a first shield end, a second shield end opposite the first shield end, and an upper shield edge; and a lock tab coupled to the shield body at the upper shield edge, the lock tab bendable relative to the shield body between a first position and a second position, wherein, in the first position, the lockable pipe shield is in an unlocked configuration, and in the second position, the lockable pipe shield is in a locked configuration.

The present disclosure provides a center bracket for adjusting a sprinkler body that is formed so as to adjust the degree of tightening of the center bracket fixing the sprinkler body, which is convenient for an operator and can reduce the working time when fine adjustment is necessary during installation of firefighting facilities or during work.
