11.3.2.1 Setting Grooving Machine
(reference from Victaulic Operating and Maintenance Manual TM-VE270/271 VSD)
1. Make sure the proper roll set is installed on the tool for
the pipe size and material to be grooved. Rolls are marked with the pipe size, part number and the color coded according to the pipe material.
2. Loosen the wing nuts and move the adjustable guards
to the full up position. Tighten the wing nuts.
3. Set the groove diameter stop to the pipe size and
schedule / thickness to be grooved by backing off the depth adjuster lock and aligning the depth adjuster with the proper.
Page 21 of 104
4. If the tool is equipped with the optional pipe stabilizer:
Retract the pipe stabilizer, if necessary, to insert the pipe onto the lower roll by loosening the locking handle and retracting the stabilizer roler with the handwheel.
5. Insert a length of pipe that is the correct size and
schedule over the lower roll. Make sure the pipe end contacts the lower-roll backstop flange. The pipe must rest directly on top of the roll and must not be skewed to one side or the other.
6. Close the valve on the hydraulic hand pump by
Page 22 of 104
7. Pump the handle of the hydraulic hand pump to bring
the upper roll down into firm contact with pipe.
8. Loosen the wing nuts and adjust each guard to
conform to and tightly pinch the pad against the pipe. Tighten the wing nuts to secure each guard in position. Remove the guard setting pad.
Page 23 of 104
9. Loosen the wing nuts and adjust each guard to
conform to and lightly pinch the pad against the pipe. Tighten the wing nuts to secure each guard in position. Remove the guard setting pad.
10. Remove the guard setting pad. Store the pad on the

Page 24 of 104
11. Open the valve on the hydraulic hand pump by turning
it counterclockwise to allow the upper roll and arm to move the full up position.
11.3.2.2 Pipes Grooving Procedure
(reference from Victaulic Operating and Maintenance Manual TM-VE270/271 VSD) 1. Before grooving the pipe, make sure the setting of
groove machine is being followed properly. Connect the tool to an internally-grounded electrical source. When roll grooving pipe that exceeds the maximum length, a roller type pipe stand must be used. The roller stand must be capable of handling the weight of the pipe, while allowing the pipe to rotate freely
2. Place the Pipe Stand at a distance slightly beyond
half the pipe length from the tool. Refer to the drawing.
Page 25 of 104
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.
Page 26 of 104
6. Connect the tool to an internally-grounded electrical
source.
7. Depress the safety foot switch momentarily to
ensure the tool is operational. The lower roll should be rotating clockwise when viewed from the front of the tool.
Remove foot from the switch.
8. Open the valve on the hydraulic hand pump turning
it counterclockwise to allow the upper roll and arm to move to the full up position.
Page 27 of 104
9. Insert a length of pipe that is the correct size and
thickness onto the lower roll. Make sure the pipe contacts the lower-roll backstop flange completely.
Remove hands from the pipe.
10. Close the valve on the hydraulic hand pump
by turning it clockwise.
11. The operator should be positioned on the safety
foot switch/hydraulic hand pump side of the tool,as shown above. Pump the handle of the hydraulic hand pump to bring the upper roll down into firm contract with the pipe.
12. Depress and hold down the safety foot switch. The
pipe will begin to rotate clockwise when viewed from the front of the tool. As the pipe rotates, begin forming
the groove by pumping the handle of the hydraulic hand pump slowly.
Page 28 of 104
Do not pump the handle of the hydraulic hand pump too fast. The rate should be sufficient to groove the pipe and maintain audible, moderate-to-heavy load on the motor/drive.
13. Continue the grooving process until the depth
adjuster lock comes into contact with the top of the tool body. Continue pipe rotation for several
revolutions to ensure groove completion.
14. Release the safety foot switch, and withdraw foot
from the switch.
Page 29 of 104
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 30 of 104
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.
Page 31 of 104
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.

Page 37 of 104
11.4.5 Tightening Nuts of Grooved Coupling (ref. Victaulic field installation handbook)
o Tighten Nuts: tighten the nuts evenly by alternating sides until metal-to-metal contact occurs at the angle bolt pads. Make sure the housings’s keys completely engage the grooves and the offsets are equal at the bolt pads. To ensure a rigid joint, equal and positive offsets are preferred. Note: It is important to tighten the nuts evenly to prevent gasket pinching. An impact wrench or standard socket wrench or standard socket wrench can be used to bring the bolt pads into metal-to-metal contact. Refer to the “impact wrench usage Guidelines” section in this manual.
o Visually inspect the bolt pads at each joint to ensure metal-to-metal contact is achieved.
o “Negative” bolt pad offsets can occur when the nuts are not tightened evenly, which produces over-tightening of one side and under-tightening of the other side. In addition, “negative” offsets can occur if both nuts are under-tightened.

Page 54 of 104
Flushing has to be done by filling the system from one and leaving the bottom valve open at the opposite end with pressurized clean potable water with required flow maintaining 10 ft/sec water velocity to carry out all debris/dirt/slag along with it.
The flushing operation shall be continued until
satisfactory cleaning is ensured then close all bottom ends.
Note: Disinfections process in fire fighting is not NFPA requirement, the disinfections chemical material will cause rusting and reactions with steel pipes. Refer to RFI Submission Reference: 421-A000-M-AV-01712
Rev.00. And if ever required by consultant the
disinfections will be prepared by specialist and will be separately submitted.
11.4.11.4 Interface
The wet pipe system employs automatic (fusible link, glass bulb, or closed type) sprinklers attached to piping containing water pressure at all times. When fire
occurs, individual sprinklers are actuated by the heat, and water flows immediately.

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.
Page 55 of 104
Where the water supply has constant pressure, the alarm valve is used without the retard chamber. In cases where a local alarm is adequate, water is admitted directly to water motor-driven gong. If no water motor gong is required.
