Operating Procedures

Operation

Heating The Triaxial Cell

Some users choose to heat the triaxial cell before applying test pressures to the
cell. Others apply test pressures while the cell is heating. In either case, the CPI
must be operated in pressure control mode during the heating process. Also, the
Confining Fluid Output valve on the CPI’s front panel should be closed to
prevent hot fluid from entering, and damaging, the reservoir.

Pressure inside the triaxial cell could reach high levels while the cell is
being heated.

This could cause personal injury or death or damage to the equipment or
specimen.

Always operate the CPI in pressure control mode during the heating process.

The process of heating the triaxial cell is included as a step in the following
procedure (

“Pressurizing and Depressurizing The Confining Fluid”

on page 37).
