SECTION 2 – OPERATING INSTRUCTIONS 2-5
Preparing the Instrument for a Test
Prior to running a test, the following steps must be performed.
Programming the Temperature Controllers
Refer to the Chandler Engineering Model 8050 Temperature Controller Manual for complete
information on how to program and operate the temperature controller.
Setting Up the Test Cell
The steps that should be used to set up the test cell are listed
below.
Warning: The plugs and vessels are not interchangeable
without voiding the pressure vessel certification.
Any replacement of the top plug, bottom plug, or
vessel, requires a new hydrostatic test certification.
Note: If cement sets in the threads during a test, the plug
may be extremely difficult to remove.
•
Replace the O-ring seals on the top and bottom plugs after
each test. The brass back-up ring must be on the side of the
O-ring closest to the threads on the plug (see drawing 84-
0045).
•
Always double-check the sealing components to make sure
they are clean and in good condition.
•
Apply a light coating of lithium grease to the inside cylinder and threads and also to each
plug. This will prevent cement from sticking to the metal and will make cleanup easier.
Avoid applying grease on the flat face of the plugs, as they will affect the transducer
signal.
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 “
T
” stamped on the wrench flat on the top end of the cylinder.
•
Place the cylinder in a vise with the bottom end up using the wrench flats on either end of
the cylinder. Use caution when placing the cylinder in the vise and do not damage the
cylinder by tightening the vise excessively, or clamp the cylinder any place other than the
flats on either end of the cylinder.
•
Make certain the sealing components are properly installed on the bottom plug. Apply a
liberal coating of high temperature grease on the o-ring.
