Benchtop Curing Chamber HTHP ,Model SXC-7360

Compressive Strength

Standard crush or non-destructive compressive-strength tests are performed on cement slurry samples under simulated downhole pressure and temperature conditions to determine the initial set time and the wait-on-cement (woc) time.

The Curing Chambers are specifically designed to prepare cement samples for comprehensive strength testing in strict accordance with API and ISO specifications. These pressurized curing chambers contain pressure vessels with controlled heating rates, and are used to cure standard two-inch cement cube samples. The curing chambers are available to cover the wide range of temperatures and pressures associated with actual conditions found in oil well cementing applications.

Testing to determine the compressive strength of samples is usually done after the samples have been cured for hours or days. The actual testing of the cubes is done with compressive strength tester. The tester will crush the samples in compliance with the API Specification 10 requirements. Curing chambers are used in laboratories involved in oil well cement reseaSXh programs, research and testing of cement additives, cement manufacturer’s quality assurance programs, and in the research and field laboratories of well servicing companies. These units, with their options, cover a wide range of operational temperatures and pressures to simulate a wide variety of down-hole conditions. Both single and dual cell units are available. The dual cell units offer the advantages of a minimum requirement of laboratory space. Dual cabinets also offer a slightly lower cost per cell because two pressure vessels are combined into one cabinet. Digital heater controller allows multiple temperature ramp profile capability to prevent over-shoot. Precise, pressure regulator allows users to set desired pressure. Pressure regulator has integrated cooling to prevent excessive heat build-up and seal failures.

FEATURES

1. Digital heater controller with multiple temperature ramp capability.

2. Special long-life seal proven to be extremely reliable under high temperature stress and does not require cooling.

3. Units operate to extremely high temperatures and pressures to include well conditions with geo-thermal temperatures and ultra deep pressures.

4. Operational life can easily exceed ten years with normal routine maintenance.

5. The internal cooling coils permit the circulation of a cooling fluid to cool the chamber - maximizing the number of tests that can be run in a day.

6. Dual cell units are cost efficient and take less laboratory space than two single cells.

7. Every curing chamber is fully tested in the factory to the maximum rating of the unit, ensuring that the instrument is completely and satisfactorily operational.

8. Over pressure safety head contains burst disc to prevent over pressurization.

9. Safety pressure switch shuts off heaters in case of pressure overload.
