General Information

POWER UNIT

The power unit on the FT1261 hose proof tester is a compact, eco-nomical, air driven hydraulic pump. The pump operates on the simple principle of pressure magnification through the use of differential areas in which a relatively large air-operated piston drives a smaller piston which provides fluid flow at high pressures.

An air regulator provides the means of adjusting hydrostatic test pres-sures.

CABINET

The cabinet construction of the FT1261 proof tester is designed to withstand a hose assembly failure.

As an additional feature, the cabinet is a self-contained reservoir capa-ble of holding approximately 10 gallons of water. The cabinet may be drained into a bucket or floor drain by opening the shut-off valve at the back of the cabinet.

PREOPERATION PROCEDURES

Uncrate the FT1261 proof tester and verify that you have received the following components:

Operating Instructions

PREFILLING

1. Close the air shut-off valve and cabinet drain valve. Adjust the air regulator to zero pressure by turning the valve handle on top of the regula- tor in a counterclockwise direction until no turning resistance is felt.
2. Open the cabinet of the tester and place the hose assembly to be tested on the floor of the tester. The umbilical hose assembly can be removed if necessary to provide unobstructed loading of hose assemblies on skids.
3. Connect the umbilical hose assembly to the hose assembly to be tested using the appropriate adapter combination or proof test tooling listed on pages 7-10 of this manual.
4. Reattach the coupling of the umbilical hose to the pumping unit if necessary.
5. Ensure that the high pressure dump valve is completely closed.
6. Open the water shut-off valve and fill the assembly allowing the tap water to force the air from the hose assembly through the non-capped end.
7. When the sample is completely filled, shut off the water and cap or plug the open end of the hose assembly.

PRESSURIZING

1. Close the cabinet and insert the “T” pin to connect both doors together. DO NOT ATTEMPT TO PRESURE TEST THE HOSE ASSEMBLY WITH THE CABINET DOORS OPEN OR WITH THE PIN NOT SECURE.
2. Reopen the water shut-off valve to supply ample water to the pumping unit during pressurization.
3. Open the air shut-off.
4. While monitoring the test pressure gauge, adjust the air regulator valve clockwise allowing the pumping action to begin. Steadily increase air pressure until the test pressure is approaching, then back off the air pressure until the pumping slows greatly. When the test pressure is reached, back off the air pressure just enough to stop the pumping action.
5. The test assembly should remain pressurized at the proof test pressure for one minute. During this time the assembly should be observed through the transparent Lexan lid. Pinhole leaks or seeping fittings may not be immediately apparent, so careful observation is important.
6. Once the test pressure has been obtained, tighten the locknut on the regulator. Subsequent assemblies can be pressurized to the test pres-sure by merely opening the air shut-off valve on the pump. The air regulator will only require readjusting when a new test pressure is required.

PRESSURIZING

(Test pressures under 2000 psi)

1. Close the cabinet and insert the “T” pin to connect both doors together. DO NOT ATTEMPT TO PRESSURE TEST THE HOSE ASSEMBLY WITH THE CABINET DOORS OPEN OR WITH THE PIN NOT SECURE.
2. Open the water shut-off valve to amply supply water to the pumping unit during pressurization.
3. With the air shut-off valve closed, adjust the air pressure regulator to provide an inlet pressure of 15-20 psi.
4. Carefully open the air shut-off valve very slightly while observing the test pressure gauge. The pressure will rise slowly. When the desired test pressure is indicated on the gauge, close the air shut-off valve. The pressure will remain constant in the test assembly for the duration of the test provided there are no leaks in the system.
5. Hold the test pressure for approximately one minute while observing the hose assembly through the transparent Lexan lid for pinhole leaks or seeping fittings.

TEST PRESSURE RELEASE

1. Close the air shut-off valve on the water pump.
2. Close the water shut-off valve located on the water pump.
3. Open the high-pressure dump valve to release the water pressure from within the hose assembly.

REMOVING THE ASSEMBLY

1. WAIT UNTIL ALL PRESSURE IS REMOVED FROM THE SAMPLE! This will be indicated by zero pressure indicated on the pressure gauge and no water draining from the pressure discharge port in the tester.
2. Open the cabinet and remove the umbilical hose and test tooling from the tested assembly.
3. Drain the remaining water from the tested assembly. It is recommended that all hose assemblies be blown dry with compressed air. Any moisture left in the assembly may cause fitting corrosion or may be incompatible with the fluid system on which the hose assembly will be used.

Maintenance

Normal maintenance requires periodic refilling of the lubricator on the water pump and cleaning the see-through lid with clean, soapy water. NOTE: Do not use petroleum or chemical solvents on the see-through lid. Use only mild detergent.

Troubleshooting

PROBLEM SOLUTION
Desired pressure not obtained while power unit is operating. 1. Check all

connections of tooling and hose assemblies for leaks.  See that high pressure dump valve is closed.
2. Open the water shut-off valve to supply ample water to the power unit.
3. Too much air in test sample.
Power unit not operating when adjusting the regulator.| 1. Supply air not connected or air shut-off valve not open.
Excess water not draining from the cabinet with the shut-off valve open.| 1. Check for obstruction in the valve or bottom of the cabinet.
