FIRE PUMP FLOW TEST REPORTS

FIRE PUMP FLOW TEST REPORTSFire pumps are an essential component of many water-based fire protection systems. They are used in instances where a building’s demand pressure exceeds the pressure that can be provided by the water supply. NFPA 25 describes the different testing methods that can be utilized for this test. Three separate scenarios occur during the annual flow test:=No-flow (Churn): This represents the pump at minimum flow which should not exceed 140% of the rated pressure

=100% rated flow: This represents the pump’s rated flow at its rated pressure=150% rated flow: This represents a pump’s flow at 65% of the rated pressure These flows are achieved by discharging specific amounts of water through the fire pump test header using approved testing devices that measure the flow and pressure coming from each test port.

WHAT IS FIRE RATED GYPSUM DRYWALL?

Gypsum is approximately 21 percent by weight chemically combined water which greatly contributes to its effectiveness as a fire resistive barrier. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively retarding heat transmission. Fire rated gypsum drywall is more fire resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to a fire exposure. Fire rated drywall is referred to as “Type X” and must be third-party certified by an independent testing and listing agency such as UL (Underwriters Laboratories Inc.) and ULC (Underwriters’ Laboratories of Canada) to meet the fire performance requirements prescribed in the ASTM C1396 (CAN/CSA-A82.27) Standard Specification for Gypsum Board. Types of Fire Rated Gypsum: Type X fire rated gypsum drywall that is 5/8 -inch (15.9mm) thick and installed on each side of nominal 2-inch x 4-inch (38x89mm) wood

Pipe Schedule Method for Firefighting Sprinkler System

Pipe Schedule Method for Firefighting Sprinkler System Pipe Schedule Method for Firefighting Sprinkler System The water demand for firefighting sprinkler systems shall be determined by either the pipe schedule method or the hydraulic calculation method, in this article we will discuss the pipe schedule method. What is pipe schedule system?! According to NFPA 13, Pipe Schedule System is defined as sprinkler system in which the pipe sizing is selected from a schedule that is determined by the occupancy classification and in which a given number of sprinklers are allowed to be supplied from specific sizes of pipe. Where can we use pipe schedule method?! New systems of 465 m2 or less. Additions or modifications to existing pipe schedule systems. Classification of occupancies according to hazard NFPA 13 classifies the occupancies according to the quantity and combustibility of contents, the expected rates of heat rel
