3. Position the pipe stand approximately 0-1/2 a degree to the left for the tracking angle. Refer to the drawing. Note: when pipe flare is excessive, right-to-left Trucking must be kept to a minimum. It may be necessary to use less than ½ a degree for the tracking angle.

4.

If the tool is properly set up in a level position, but the back end of the pipe is higher than the end being grooved, the pipe may not track, in addition, excessive flare may occur on the pipe end. Refer to the “Tool Setup” section and the drawings above for tool setup and pipe positioning requirements.

5.

Before grooving, make sure all instructions in the previous sections of this manual have been followed.

15. Open the valve on the hydraulic hand pump by turning It counterclockwise to release the pipe. Remove the Pipe from the tool.

16. If no more roll grooving will be performed for a while,disconnect the tool from the electrical source. 

The groove diameter must be within specification for the diameter and wall thickness of pipe. The groove diameter should be checked and adjusted, as necessary, to ensure grooves remain within specification.

11.3.2.3 Pipes Threading Procedure 1. A die head will be attached to cut the thread. 2. Machine now have the ability to threads pipes. 3. A heavy duty pipe threader can also cut your pipe into workable sections. 4. The pipe threading machine will be used to thread the end section of your pipe. 5. Inspect the pipe threader before beginning and replace dies or any parts that show signs of wear. 6. Mount your pipe firmly in the pipe vise by placing it in the vise and then tightening until it is held tightly.

Page 29 of 104

THE ENGINEER:


THE CONTRACTOR:




7. Cut the end of the pipe cleanly and squarely by using a pipe cutter. The pipe cutter will have a thin cutter wheel, which will slice through pipe as you guide it in the space. Be sure to wear goggles and protective gear. 8. Ream the cut end of the pipe to remove any burrs from the cut using a reamer, which is a cylinder – shaped rotary cutting tool that you run smoothly across the freshly cut edges of the pipe to remove rough edges. 9. Select your die head according to the size and type of pipe you are threading and the thread from your require. 10. Place the die head over the pipe on the threader. 11. Press steadily on the front of the die head, while simultaneously pushing the handle down to start threader. Before placing too much pressure on the handle, check to be sure that the ratchet pawl is engaged. 12. Use weight as leverage to apply pressure on the handle, while holding it firmly. Be sure to maintain proper footing and balance for maximum control. Never use a tool or mechanism to hold the handle in place in order to free your hands, this can be dangerous and could result in injury. 13. Apply threading oil generously while threading. Using on oil too thin as a substitute for threading oil can result in sub-standard threading. 14. Cease threading when the end of the threading die is flat against the end of the pipe. When the die is even with the pipe, that means the correct threading size has been reached. If you continue pushing after this point, you will damage the thread.

THE CONTRACTOR:




15. Reverse the ratchet mechanism and turn the die head in the opposite direction. Be care full to maintain control of the threader as the dies are removed. Threads can be damaged when the die head is being removed if you don’t maintain control and move the piece smoothly. 16. Stand the pipe on end and gently tap it to remove any particles that may be lodges within. 17. Clean the pipe with cloth, removing any oil. Be careful, the threads will be very sharp. 18. Seal the threading with a pipe thread compound when attaching the pipe to the connector. 19. Clean the pipe threader machine thoroughly after use so the oils and metal pieces do not damage the machine, which could cause sub-standard threading during your next project.

Alarm Check Valve – the wet pipe system is controlled by an alarm check valve. When a sprinkler activates, the flow of water raises the alarm valve clapper from its seat, thereby lifting the pilot valve disc from the nozzle. These permits water to enter the alarm line. A water motor gong is actuated by the flow. An optional pressure switch may be attached on the alarm line to provide an electric signal. The electric can be send to the building’s main fire alarm control panel.



Also, the room has to be completely sealed so that FM200 discharged will not escape. Escaping any amount of FM200 agent will result a lower concentration which would be considerable especially FM200 concentration for the room is a minimum as 7% volume by volume.



7.7.2.3* Review of Enclosure Integrity – all total flooding systems shall have the enclosure examined and tested to locate and effectively seal any significant air leaks that could result in a failure of the enclosure to hold the specific agent concentration level for the specified holding period. Quantitative results shall be obtained and recorded to indicate that the specified agent concentration for the specified duration of protection is in compliance with Section 5.6, using an approved blower fan unit or other means as approved by the authority having jurisdiction. HVAC Systems should be turned off prior to the gas discharge and also any openings related with HVAC Systems are to be closed to assure a complete sealing of the room. Any openings of the duct to the room in fresh air or return ducts are to be closed completely by a motorized fire damper. Most of the motorized fire dampers are of spring return actuator type (fail safe). The actuator of the damper will get a signal from the pre-discharge (2nd Stage) relay and then will close the damper to ensure the total sealing of the room.



Sealing Void: (Rooms with false ceiling) – unless specified, ceiling void normally contains lighting circuits and HVAC ducts. They don’t need to be protected by FM200 generally. Ceiling void can be sealed properly and isolated from the room protected by FM200. For that purpose, false ceiling should be made of fire rated air tight materials. Ceiling tiles (perforated or nonperforated) cannot be considered to fall in this category. When the ceiling void cannot be isolated comply from the room, theceiling void should be protected bey FM200 system. But, in this case, it is to be made sure that the walls are to be extended to the ceiling slab so that the complete isolation of the room with ceiling void is obtained from other rooms.



Raised Floor – are normally installed in the control rooms, computer rooms, server rooms, UPS rooms, Data rooms, Telephone rooms, etc., for running the data cables. In this case, floor voids are considered as electronic hazards and are to be protected by FM200 systems.

Pressure Gauge w/ Low Pressure Switch



The following procedure is used to install and/or replace the pressure gauge with low pressure switch on a changed cylinder. This device can be installed in the fill port on a container that is charged by using the following steps:



Important Note: Cylinder must be securely mounted in the cylinder racking or cylinder strap before installing pressure gauge.

1. Prior to Assembly; lubricate the Pressure Gauge Assembly O-Ring (p/n 02-10674 with Molycoat 55 or equal. Use care not to get lubricant into pressure port. Notes: “Do Not” apply Teflon Tape to Pressure Gauge Adaptor threads. “Do Not” cross thread the Pressure Gauge Assembly during installation. 2. Remove and retain Plug from pressure gauge port. 3. Screw in the Pressure Gauge Assembly (Hand Tight) until resistance is felt. Use locking pliers or wrench to screw in the Pressure Gauge Assembly until it bottoms out. This will open an internal check valve and pressurize the gauge. 4. To align the Pressure Gauge, un-screw Pressure Gauge Assembly up to 1 turn.

THE CONTRACTOR:




5. Leak check around the pressure gauge port using Snoop leak test fluid or equivalent. If a leak is detected, remove the Pressure Gauge Assembly from the ProInert vaolve and remove the lubricant and contaminants from the O-Ring, threads and valve port using isopropyl alcohol and soft clean cloth. Lubricate the ORing with Molycoat 55 or equal land reinstall. Leak test around the pressure gauge port. If a leak is detected, remove the Pressure Gauge Assembly from the Inert Valve, remove the O-Ring, install a new ORing, lubricate the O-Ring with Molycoat 55 or equal, install the Pressure Gauge Assembly in the ProInert valve, and leak test around the pressure gauge port.  Warning: When removing the Pressure Gauge Assembly from the pressurized ProInert cylinder, a “pop” sound will occur. This is the result of a minor amount of gas being trapped in the pressure gauge port; this is a normal occurrence. If a pressure leak continues after backing-off the Pressure Gauge Adaptor five turns (O-Ring is visible), the Schrader core did not reseat, do not remove the Pressure Gauge Assembly, reinstall and follow the proper procedure to empty cylinder and replace Shrader core. Do Not attempt to remove the pressure gauge from adoptor.

Automatic Pre-action Sprinkler System



As per NFPA 25: Chapter 3.6.4.5. A preaction sprinkler system employing automatic sprinklers attach to a piping system that contain air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers.



Pre-action sprinkler system shall be designed in accordance with Exhibit “D2” 211316 – Dry-Pipe Sprinkler Systems.



These systems are specially designed for the protection of high value “Business Critical” areas where sensitive electrical equipment or goods are stored to provide prior warning of system discharge or prevent system discharge caused by accidental damage to a sprinkler or system pipe work.



A pre-action sprinkler system comprises a standard deluge valve sprinkler system and an independent system of heat or smoke detectors installed in the same areas as the sprinklers.



The deluge valve is a diagphragm style valve that depends upon air in the diaghragm chamber to hold the diagram closed against the water supply. Any accidental damage to a sprinkler or a detector head in a “non-fire” situation will not bring the contol valve into action but will cause both visual and audible alarms to be raised to alert the building’s fire safety officer to the situation.

Page 92 of 104

THE ENGINEER:


THE CONTRACTOR:






In the event of a fire, when two or more detector heads operate, they send a signal to the main fire control panel. On receipt of this signal, the fire control panel operates the solenoid release valve, releasing the pressure off the diaphragm unit to open the Deluge valve and discharge water into the system in readiness for a sprinkler head to open when it reaches its designated operating temperature.



This process provides the building’s fire safety officer with prior warning of the impending event so that the Company’s established fire control plan can be immediately initiated to minimize the impact of the fire threat.



The size of the deluge valve, its flow rate, the system water supply pressure and type of detection system are all determined by the size and type of fire risk involved.



Pre-action fire sprinkler systems employ the basic concept of a dry pipe system in that water is not normally contained within the pipes. The difference, however, is that water is held from piping by an electrically operated valve, known as a pre-action valve. Valve operation is controlled by independent flame, heat, or smoke detection.



Two separate events must happen to initiate sprinkler discharge. First, the detection system must identify a developing fire and then open the pre-action valve. This allows water to flow into system piping, which effectively creates a wet pipe sprinkler system. Second, individual sprinkler heads must release to permit water flow onto the fire. In some instances, the pre-action system may be set up with a double interlock in which pressurized air or nitrogen is added to system piping. The purpose of this feature is twofold: first to monitor piping for leaks and second to hold water from system piping in the event of inadvertent detector operation. The most common application for this system type is in freezer warehouses.

Installation Deluge System



As per NFPA 25: Chapter 3.6.4.3. a sprinkler system employing open sprinklers that are attached to a piping system that is connected to a water supply through a deluge valve that is opened by the operation of the detection system installed in the same areas as the sprinklers. When this valve opens, water flows into the piping system & discharges from all sprinkler.



Similar to a pre-action system except the sprinkler head are open and the pipe is not pressurized with air.



Deluge system are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system.



The detection system is installed in the same area as the sprinklers.



Deluge system are used in places that are considered high hazard areas.



Deluge systems are used in the protection of large Aircraft Hangers as one primary means of fire protection. Deluge system are needed where high velocity suppression is necessary to prevent fire spread.





The deluge valve must be opened as signaled by a fire alarm system. The initiation device signals the fire alarm panel, which in turn signals the deluge valve to open, allowing water to enter the piping system. Water flows from all sprinklers simultaneously.

Page 95 of 104

THE ENGINEER:


THE CONTRACTOR:




11.4.16.1 Interface  Deluge system are used for fast, total application of water in Extra-Hazardous areas and in waterspray systems. Deluge valves are essentially check valves with a clapper latched in the closed position (see picture below). The actuating system unlatches the valve, allowing the water to enter the piping system and flow out the heads.



Deluge valve employs a single differential diagphragm in which the water pressure bears on both sides, while the top side adjoins a closed chamber (see picture below). The actuating system opens the closed chamber, allowing the water to push the diaphragm up and off the water seat, releasing water to the system.
