General Information
Introduction
This manual contains installation, operation, and maintenance instructions for the
Chandler Engineering Model 5265 Static Gel Strength Cement Analyzer.
Description
The 5265 Static Gel Strength Cement Analyzer (SGSA) is an instrument that
measures the static gel strength of API cement under high temperature and high-
pressure conditions. The instrument captures ultrasonic signals that are passed
throughthe sample then performs post-processing of the data to determine the
static gel strength (SGS) versus time plot.
Each 5265 autoclave connected as part of the SGSA system is equipped with an
internal processor board that sends and receives an ultrasonic pulse through the
slurry, performs digital signal processing of captured data and, as an option,
measures the transit time of the pulse through the slurry.
After the processor board computes the SGS data, it is sent to the I/O board
located on the rear of the autoclave. The I/O board is connected to the RS-232
serial communication port located on the rear of the PC or to another autoclave
I/O board by a four-wire RS-485 communication cable.
Additionally, as an option, the instrument may be used to determine the
compressive strength of the cement using the same algorithms and method found
in the Model 4265 Ultrasonic Cement Analyzer (UCA).
Features and Benefits
The major features of the 5265 Static Gel Strength Analyzer (SGSA) are listed
below:
• Easy to install and use.
• Uses PC based Chandler Model 5270 Data Acquisition System for data
retrieval, analysis and storage.
• Tests stored in database may be sorted and retrieved based on user specified
data base fields.
• Built-in pump and relief valve for sample pressure control.
• Optional cement compressive strength measurement (UCA).
• Optional external chiller system.

1-2 SECTION 1 – INSTALLATION
Connecting Serial Power
Use the configuration software (SIXBCCD.EXE) to configure the individual data channel
addresses.
A basic schematic for connecting one autoclave to another is shown in the following figure.
One autoclave in each 5265 SGSA system must be connected to serial port COM1
on the host computer using a standard 25 pin male to 25 pin female or 25 pin male
to 9 pin female RS-232 serial cable, depending on the computer.

SECTION 2 – OPERATING INSTRUCTIONS 2-1
Section 2 – Operating Instructions
Front Panel Controls
The figure below shows the front panel and all the associated controls. The
description of each control will follow the figure.
Air Inlet Gauge
This gauge displays the pressure of the air supply connected to the autoclave. The
pressure should be between 50 and 100 psig (340 and 690 kPa) when the pump is
not in use.
Pump PressureAdjust Regulator
This regulator is used to control the pressure of the air supplied to the pump.
Pump Air Pressure Gauge
Indicates the pressure of the air supplied to the pump. Each 5 psig (35.5 kPa)
pressure applied to the pump results in approximately a 1000 psig (7000 kPa)
hydraulic pressure output from the pump.
Relief Valve
The relief valve or back-pressure regulator may be used to set the upper limit on
the system pressure up to 10,000 psig (69,050 kPa). Turn the relief valve knob
clockwise to increase pressure and counterclockwise to reduce pressure. To
configure the pump and relief valve to control pressure automatically will be
discussed in the section titled Pressure Control, discussed later in the section.

2-2 SECTION 2 – OPERATING INSTRUCTIONS
Verification of Signal Strength
You can verify the proper signal strength by running the following test:
1. Set up instrument to run a water test.
• Starting temperature: Room temperature
• Initial Pressure: 1,000 psig
2. Fill slurry cup with water.
3. Run test.
4. Initial gel value should be between 7000 – 7500.
5. If the initial gel value does not fall within these parameters, disassemble, inspect and
clean if necessary the transducer and end cap.
6. Rerun test.
Running a Test
Relief Valve Shut-off
The relief valve is only usable up to pressures of 10,000 psig. If it is necessary to
operate the autoclave at pressures above 10,000 psig, The RELIEF VALVE
SHUTOFF must be turned clockwise to the closed position.
Note: Closing the relief valve shutoff valve will also isolate the internal pressure
transducer. The pressure transducer will not measure pressures above 10,000
psig (69,050 kPa).
Pump Switch
Opens or closes a solenoid valve which controls the flow of air to the pump.
Turning this switch to the ON position causes the pump to increase pressure in the
test cell. Turning the switch to the OFF position stops the pump from operating.
Pump Water Switch
This switch is used to control the flow of water to the pump and test cell. This
switch must be OFF any time the test cell is not installed. This switch must be
ON to fill the tubing connected to the test cell with water or to operate the pump.
Coolant Switch
Used to control the flow of coolant to the heating/cooling jacket. This switch
must be OFF during a test, but should be turned ON following a test to cool the
heater and test cell.
If the optional chiller is used, the coolant switch has three settings: ON, OFF,
AUTO. The ON setting circulates chilled fluid through the heating/cooling
jacket, the OFF setting disables the heating/cooling feature, and the AUTO setting
allows the temperature controller to control the chiller. After the cool-down
segment of a temperature profile is complete, it is recommended to place the

SECTION 2 – OPERATING INSTRUCTIONS 2-3
coolant switch in the OFF position to avoid possible temperature oscillations at
temperatures above room temperature.
Pressure Release Valve
Used to manually release pressure from the test cell. Valve must be closed during
testing except when it is necessary to manually release pressure. Valve must also
be closed when removing test cell with cooling water ON or else a significant
water leak will occur.
Cylinder Pressure Gauge
Displays the pressure inside the test cell.
Temperature Controller
Used to control the temperature in the test cell.
Heater Switch
Used to turn the flow of current to the heater ON or OFF. Switch must be in the
ON position during testing and should be in the OFF position as a safety
precaution at other times.
Main Power Switch
Used to turn the 220VAC power to the heater and internal solenoid valves
instrument ON or OFF. Switch must be in the ON position during testing.
Instrument Power Switch
Used to turn the power to the internal instrumentation ON or OFF. Switch must
be in the ON position during testing. The instrument power may be connected to
an uninterruptible power supply (UPS) if desired.

Ref Cable Connector
This connection is not used on the 5265 Autoclave.

2-4 SECTION 2 – OPERATING INSTRUCTIONS
Monitor Cable Connector
This connector is used for monitoring the ultrasonic signals within the test cell. Normally it
is not used. It may be used during system testing.
Top Transducer Connector
The coaxial cable attached to the top transducer must be mated to this connector prior to
beginning a test.
J Thermocouple Connector
The thermocouple that is attached to the top plug must be plugged into this connector prior to
the beginning of a test and any time that it is necessary for the temperature controller to
operate. If the thermocouple is not connected, the temperature controller will display “SBr”
and will not function.
Main Power Connection
Located beside the fuses, it requires a twist lock plug to connect the power. The power
required will be 208-240 VAC, 10A.
Fuses
There are two fuses (2.5A, 250VAC) located in the Instrument Power Receptacle. To check
these fuses, remove the power cord and pry off the access panel with a small screwdriver.
Right Rear Panel
The right rear panel contains all the connections for hydraulic and pneumatic utilities.
Air Inlet, Pump Water Drain/Inlet
These connectors are used to connect the pneumatic and hydraulic utilities.
High Pressure Inlet (optional)
This high-pressure connector exists so that pressure may be controlled with an
alternate pressure control system.

SECTION 2 – OPERATING INSTRUCTIONS 2-5
Operating the Instrument
1. Install the Model 5270 Data Acquisition Software in accordance with the instructions found in the
software manual.
2. Connect power to the instrument using the cord and twist-lock connector supplied with
the autoclave. It is recommended that each individual autoclave be connected to a
separate circuit breaker or fuse. A 15A fuse or circuit breaker is recommended. A
separate power input exists for the internal electronics. This arrangement permits the use
of an uninterruptible power supply (UPS) to protect the data acquisition electronics and
test data from brief power failures.
3. Connect the coolant to the connector labeled COOLANT INLET on the rear panel of the
instrument as shown previously. The fitting is a 1/4-inch female NPT fitting. If water is
used for cooling, the water must be clean and free of debris that could cause failure of the
pump or relief valve. If in doubt, a water filter is recommended.
4. If the optional chiller is being used, connect the outlet port of the chiller system to the
COOLANT INLET port and the COOLANT DRAIN port to the chiller inlet port.
Configure the chiller to operate at the minimum set point temperature (41°F, 5°C).
5. Connect the pressurizing water to the connector labeled PUMP WATER INLET on the
rear panel of the instrument as shown previously. The fitting is a 1/4-inch female N.P.T.
fitting. The water must be clean and free of debris that could cause failure of the pump or
relief valve. If in doubt, a water filter is recommended.
6. Connect the water drain line to the connector labeled PUMP WATER DRAIN on the rear
panel of the instrument as shown previously. If water is used as a coolant, the
COOLANT DRAIN may also be connected to the water drain line. If an external chiller
is used, the COOLANT DRAIN is connected to the chiller return. The fittings are 1/4-
inch female NPT fittings.
The drain system must be capable of handling hot water up to 212°F (100°C) or brief
surges of up to 400°F (204°C) steam for short periods of time during initial cooling of the
instrument. If two or more autoclaves are connected to a common drain line, it is
recommended that the common drain be 3/8-inch (10mm) inside diameter, minimum. It
is also recommended that the drain system be all metal. Copper tubing with brass fittings
is satisfactory.
7. Connect the air supply to the connector labeled AIR INLET on the rear panel of the
instrument. The fitting is a 1/4-inch female N.P.T. fitting. The air should be dry and
relatively free from dirt and oil. The air should be supplied at a pressure of 50-100 psi
(340-690 kPa). Compressed nitrogen may also be used in place of the compressed air if
necessary.

2-6 SECTION 2 – OPERATING INSTRUCTIONS
Preparing the Sample and Cell for a Test
The recommended procedure for preparing the test cell and slurry for testing are
outlined in the following steps:
1. Always check the sealing components to make sure they are clean and in good condition. If
the O-rings are deformed or hardened replace them.
2. Apply a light coating of lithium grease to the inside cylinder and threads and also to each plug.
Avoid apply grease on the flat face of the plug and base as this will affect the transducer signal.
This will prevent cement from sticking to the metal and will make cleanup easier.
Note: The test cylinder is tapered from top to bottom, with the smallest diameter at
the top. This is to facilitate removal of the cement sample from the test cell.
The top of the cylinder is denoted by the letter Tstamped on the wrench flat
on the top end of the cylinder.
3. Place the bottom plug in a vice. Install seal ring and O-ring. Apply a thin coat of high
temperature grease on the O-ring and sealing ring.
4. Screw the cylinder onto the bottom plug located in the vise with the cylinder end marked Tat the
top. It is recommended that the plug be screwed in by hand and that the plug be tightened so that
it just contacts the cylinder. Further tightening after the plug has contactedthe cylinder will not
cause more effective sealing, and will cause plug removal difficulty.
5. Install the transducers in the top and bottom plug using the spring and transducer support plug.
Always place a thin coating of high temperature ultrasonic couplant on the sensor each time it is
removed. Use the couplant sparingly. Excessive buildup of couplant can lead to instrument
malfunction.
6. Mix the slurry for the test in accordance with API Spec 10 procedures. Approximately 200 mL
of slurry is required to fill the cell.
7. Pour approximately 200cc of cement slurry into the greased test cell. Be careful not to get
cement into the threads. If cement sets up in the threads it may make plug removal and
installation difficult.

SECTION 2 – OPERATING INSTRUCTIONS 2-7
8. Continue to pour cement in test cell until level is 1/4 inch (6mm) below the circular lip in
the cylinder. Use the Slurry Level Gauge to obtain the proper fill level. The slurry
should touch the lower tab marked WET but not touch the upper tab marked DRY. Do
not overfill the test cell, or cement will be forced into the pressure and/or thermocouple
ports, and plug them.
9. Use a small amount of water to continue filling the cell up to the water fill line indicated
on the slurry level gauge.
10. Screw the top plug into the top of the cylinder. It is recommended that the plug be
screwed in by hand and that the plug be tightened so that it just contacts the cylinder.
Further tightening after the plug has contacted the cylinder will not cause more effective
sealing, and will cause plug removal difficulty.
11. The test cell is ready to be installed in the heating jacket.
12. Wipe the cylinder assembly clean and place in autoclave chamber. Carefully guide the
bottom transducer cable through the bottom of the heater assembly and out the front
panel of the instrument. Be certain that the cylinder is not sitting on the cable. Do not
crimp the cable in any way since it can change the signal characteristics. Connect the
cable to the connector on the front panel.
13. Align the pressure port in the top plug with the high-pressure filter on top of the
autoclave assembly. Rotate the cell clockwise to align.
14. Position the filter with the arrows (located on the side) pointing in the downward position
and attach the short end of the U-tube connection to the top of the filter, as shown in the
picture.
15. Attach the filter assembly into the bulkhead located on top of the instrument.
16. Connect the longer end of the tube into the top of the
cylinder. Hand-tighten initially to start the threads, then
use a 5/8” wrench to tighten.
17. Connect the top transducer cable to the BNC connector
labeled Top Transducer at the back of the autoclave.
18. Install the thermocouple in the other high-pressure port in
the top plug. Hand-tighten only.
19. Connect the thermocouple cable to the receptacle labeled
J Thermocouple at the back of the autoclave.
20. Turn ON the water supply switch until water exits the
thermocouple vent hole. Tighten the thermocouple
connection using a 5/8-inch wrench.
Note: Use a rag or paper towel to catch water that exits the
thermocouple vent.
21. The test cell and autoclave are now ready to begin a compressive strength test.
Running a Test
This section describes the steps used to control pressure and temperature in the
5265 autoclave.

Bulkhead 15.
14.
16.

2-8 SECTION 2 – OPERATING INSTRUCTIONS
1. Make certain the test cell is installed properly, the HIGH PRESSURE INLET port on the rear
of the instrument is plugged, the PUMP switch is in the OFF position, the PUMP WATER
valve is turned to the ON position, and the instrument is supplied with compressed air.
2. Turn the PUMP PRESSURE ADJUST regulator clockwise until air pressure is sufficient to
raise pressure to the desired pressure set point. Each 5 psig (34.5 kPa) air pressure results in
approximately 1000 psig (6895 kPa) hydraulic pressure. The air pressure should not exceed
100 psig (690 kPa). Note that the pump may not be capable of achieving pressures in excess
of 16,000 psig without using heat to expand the fluid and increase pressure.
3. Turn the Relief Valve knob clockwise until the release pressure is sufficient to prevent the
relief valve from opening at the desired pressure set point.
4. Turn the PUMP switch to the ON position until pressure exceeds the desired set point. Turn
the PUMP switch to the OFF position. Make certain the system is holding pressure before
proceeding.
5. Turn the Relief Valve knob counterclockwise slowly until the test cell pressure begins to drop.
Continue turning the regulator knob slowly until the pressure in the test cell equals the upper
limit of the desired test pressure.
6. Turn the PUMP PRESSURE ADJUST regulator counterclockwise until the air pressure is
approximately zero.
7. Turn the PUMP switch to the ON position.
8. Slowly turn the PUMP PRESSURE ADJUST regulator knob clockwise until the pump begins
to stroke. Continue to slowly turn the regulator knob clockwise untilthe lower limit for the
control pressure is achieved. Note that failure to apply any pressure to the slurry may result in
a loss of transit time signal through the slurry.
Temperature Control
Refer to the 8050/8051 Temperature Controller Manual for information on how to program and
operate the temperature controller. When the controller has been programmed and the Processor is
operating properly, the test may be started by turning the HEATER switch to the ON position and
selecting CM.1=AUTO on the temperature controller.
1. If the chiller is being used, place the coolant switch in the AUTO position. After the cool-
down segments of a temperature profile are complete, it is recommended to place the coolant
switch in the OFF position to avoid possible temperature oscillations at temperatures above
room temperature.
2. To end the test, turn the HEATER switch to the OFF position.
3. Turn the Temperature Controller OFF by pressing the Advance button so that the
controller displays CM.1 and pressing the up or down arrow buttons to select OFF.
Note: Always leave the controller in the OFF mode with the HEATER switch turned
OFF when the thermocouple is not installed in the cylinder.
Ending a Test
1. Turn ON the COOLANT switch to cool the test cell. Monitor the test cell
temperature using the Temperature Controller. Use the pump to maintain
pressure on the test cell until the cell is cool. When the temperature is below
200°F (93°C) the pump switch may be turned to the OFF position and the
PRESSURE RELEASE valve turned to the open position. Failure to maintain
