API St 976-2018 pdf download.Refractory Installation Quality Control— Inspection and Testing of AES/RCF Fiber Linings and Materials.
1 Scope This standard provides installation quality control procedures and lining system design requirements for AES/RCF fiber linings, and may be used to supplement owner specifications. 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. The lining described in this standard is for internal refractory linings on the process side of the equipment. External insulation and jacketing are not covered in this standard. 2 Normative References The following referenced documents are indispensable for the application of this document.

3.8 cold-face 4 The surface of a refractory lining against the metal casing surface. 3.9 compliance datasheet 5 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. 3.10 dual layer 4 Refractory construction comprised of two refractory materials wherein each material performs a separate function (e.g. ceramic fiber over insulating monolithic layer). 3.11 EM 4 Original equipment manufacturer or equipment supplier with overall responsibility for design, fabrication, and delivery of a finished product. 3.12 expansion joint A non-bonded joint in a lining system with a gap designed to accommodate thermal expansion of adjoining materials; commonly packed with a temperature-resistant, compressible material, such as ceramic fiber. 3.13 fabricator Company responsible for the overall fabrication of the fired equipment in which refractory is installed. 3.14 fiberboard Rigidized fiber, vacuum formed using bulk fiber, fillers, and binder (usually colloidal silica). Once formed and dried, it is supplied in a rigid board form. 3.15 fiber component fabricator A third party separate from the refractory manufacturer and the installation contractor engaged in a business of purchasing fiber and anchor materials that are fabricated into modular lining components. These components are then purchased and installed by the installation contractor. 3.16 form 4 — Shaped: sold as finished units, installed as building blocks. — Monolithic (unshaped): final shape formed upon application. — MMVF/AES/RCF fiber. 3.17 fuels fired 4 The type of fuels fired in the heater. Corrosive ash and impurities in the fuel (e.g. sulfur, alkali, and heavy metals) will guide selection of the type or form of refractory and the method of construction for refractory linings.
3.19 hot-face layer 4 Refractory layer exposed to the highest temperatures in a multilayer or multicomponent lining. 3.20 hot-face temperature 4 Temperature of the refractory surface in contact with the flue gas or heated combustion air. This is the temperature used for thermal calculations for operating cold-face temperature and heat loss. 3.21 inspector The party or individual with whom the owner has contracted or otherwise designated to monitor refractory installation work. 3.22 installer 4 Company or individual responsible for installing the refractory lining. 3.23 interface temperature 4 Calculated temperature between any two adjacent layers of a multi-layer or multicomponent refractory construction. 3.24 low bio-persistence 4 Materials having solubility in body fluids and designed to be cleared from the lungs very quickly if they are inhaled. Clearance occurs through the body’s natural defense mechanisms.
