API 936 Refractory Personnel Course Scope
This standard provides installation quality control procedures for monolithic refractory linings and may be used to supplement owner specifications.
API 936 Refractory Personnel Course Materials, equipment, and personnel are qualified by the methods described, and applied refractory quality is closely monitored, based on defined procedures and acceptance criteria. The responsibilities of inspection personnel who monitor and direct the quality control process are also defined.
Terms and Definistions
For the purposes of this document, the following definitions apply.
NOTE See Annex A for a glossary of additional refractory terms that are not referenced in this standard.
abrasion resistance
The ability to withstand the effects of an eroding particles for an extended period without significant loss of material or other damage.
EXAMPLE A vapor stream containing solid particles.
NOTE For refractory materials, abrasion resistance is measured in the form of eroded volume loss in accordance with ASTM C704.
application qualification testing
Preinstallation simulation of production work that is visually inspected, sampled, and tested to verify that application equipment and personnel are capable of meeting specified quality standards.
as-installed testing
Testing of refractory materials sampled from the installation to confirm that they meet specified physical property standards.
biscuit
A refractory piece formed within an area completely enclosed by the anchoring system.
EXAMPLE A hexmetal or flexmesh cell.
NOTE The biscuit has the shape of the enclosed area and the thickness of the lining. Biscuits are normally independent of each other except for limited connections through perforations in the anchoring system.
castable
A combination of refractory grain and suitable bonding agent that, after the addition of a proper liquid, is installed into place to form a refractory shape or structure that becomes rigid because of a chemical action.
casting
The application of wet mixed castable refractory by placing (possibly with the aid of vibration), pouring, or rodding.
chemical-setting
Developing a strong bond by chemical reaction. These refractories include phosphate-bonded plastics and ramming mixes.
cold crushing strength CCS
A measure of a refractory’s ability to resist failure under a compressive load as determined at room temperature after drying and/or firing.
NOTE CCS is calculated by dividing the total compressive load at failure by the specimen cross-sectional area.
cold wall
An insulating refractory lining system with a metal shell temperature less than 500 °F (260 °C).
compliance datasheet
A list of mechanical and chemical properties for a specified refractory material that are warranted by the manufacturer to be met if and when the product is tested by the listed procedure.
contractor
The party or parties responsible for installing refractory in the owner's equipment.
conventional refractories
Castable refractories containing greater than 2.5 % CaO.
curing
Process of bond formation in a newly installed monolithic refractory.
NOTE For hydraulic bonded castables, curing occurs at room temperature and is facilitated by an excess of water being present to react with the cement component. For phosphate-bonded plastic refractories, heating to 500 °F to 700 °F (260 °C to 370 °C) is required to form the bond.
cutback
Preset refractory trimmed from the lining surface via a cutting action to give the final lining thickness dimension, usually in a gunning installation.
density
The mass of a unit volume of a substance. It is usually expressed either in kilogram per cubic meter, grams per cubic centimeter, or in pounds per cubic foot.
dry gunning
Pneumatic placement of gunning mixes where water is added at the nozzle.
