General Information
Introduction
This manual contains installation, operation, and maintenance instructions for the Chandler
Engineering Model 1910 Pressurized Curing Chamber.
Purpose and Use
The Pressure Curing Chamber is used for curing tensile or compression specimens of oil well
cements at elevated temperatures and at pressures above atmospheric, simulating conditions
in the well.
Briefly, the procedure is to prepare the test specimens according to API Spec. 10
(1)
. The
specimen slurries are poured into molds, and the molds are lowered into the pressure curing
cylinder. The cylinder plug is installed, the thermocouple is inserted into the cylinder head,
and the cylinder is filled to expel air. Heat and pressure is applied to the cylinder in
accordance with applicable schedules of API Spec. Maximum pressure and temperature are
maintained until shortly before the end of the curing time specified. The temperature is then
reduced, pressure is released, and the test specimens are removed for testing.
Description
Safety features are incorporated into the curing chamber. A rupture disc rated at 25,500
psi/175.8 MPa is incorporated as an additional safety feature.
