SAES-N-140Refractory Ceramic Fiber Installation Requirements
SAES-N-140 standard provides the minimum mandatory requirements for the installation, testing, and inspection of refractory ceramic fiber (RCF) systems for process equipment. Here are the key points covered by this standard:
- The standard applies to the installation and repair of RCF systems in process equipment.
- For equipment and refractory systems not explicitly covered by this standard, it is advised to consult with a Saudi Aramco Engineer to determine the applicability of this standard.
- The standard can be included and referenced in purchase orders related to RCF systems.
- It covers both the installation of new RCF systems and the repair of existing RCF systems.
For detailed guidelines and specific requirements related to the installation, testing, and inspection of RCF systems, it is recommended to refer to the full SAES-N-140 standard document. It will provide comprehensive information on procedures, materials, and quality control measures to ensure the proper installation and performance of refractory ceramic fiber systems in process equipment.
Industry Codes and Standards for SAES-N-140
- ASME SEC IX: This is a qualification standard published by the American Society of Mechanical Engineers (ASME). It sets the requirements for the qualification of welding and brazing procedures, welders, brazers, and welding and brazing operators. It covers the testing and certification of individuals involved in welding and brazing operations.
- SSPC SP 1: This standard, published by the Steel Structures Painting Council (SSPC), is called “Solvent Cleaning.” It provides guidelines for the removal of dirt, oil, grease, and other contaminants from surfaces before applying paint coatings. It specifies the use of solvents for cleaning purposes.
- SSPC SP 3: This standard, also published by SSPC, is called “Power Tool Cleaning.” It outlines the procedures for surface preparation using power tools such as power sanders, grinders, and wire brushes. The goal is to remove loose paint, rust, and other coatings from surfaces to achieve a clean substrate.
- SSPC SP 7: This standard, known as “Brush-Off Blasting,” provides guidelines for surface preparation using brush blasting techniques. Brush blasting involves the use of abrasive materials propelled by compressed air through a brush or nozzle to clean the surface and remove contaminants.
While these standards may not be specifically related to refractory ceramic fiber (RCF) systems as covered by SAES-N-140, they are relevant in their respective fields of welding qualification, surface cleaning, and preparation for painting steel structures. It’s important to consult the appropriate standards and guidelines specific to RCF systems to ensure compliance with the requirements of SAES-N-140.
Installation
The information you provided outlines the installation requirements for refractory ceramic fiber (RCF) systems. Here are the key points:
9.1 General:
- Modular construction should follow specific installation methods, such as the uni-directional with batten strip method.
- Batten strips should be folded once or twice, depending on the service temperatures.
- Installation of RCF modules should be done according to the RCF Designer’s installation drawings and AB-036395.
- Orientation of RCF modules around doors should be perpendicular to the door frame.
- Joints between RCF modules and castable refractory should be packed with a folded batten strip.
9.1.2 Layered Blankets and Blanket Board Construction:
- Lap joint method should be used for blanket installation.
- Butt joint method should be used for blanket board installation.
- Installation of blankets and blanket boards should be done according to the RCF Designer’s installation drawings and AB-036400.
9.2 Anchor Materials:
- The materials for anchors should comply with AB-036395 and AB-036400.
9.3 Anchor Layout:
- Anchor layout should follow the detailed drawings provided by the RCF Designer.
9.4 Installation of Vapor Barrier and Coating:
- Coating should be applied according to the instructions provided by the coating manufacturer.
- Refractory material should be installed once the coating is dry to the touch.
- Additional metal vapor barrier may be required for high fuel sulfur content, positioned above the calculated acid dew point.
9.5 Veneering with RCF:
- Veneering should be done using the parquet method of installation.
- Installation of RCF veneering over brick or castable refractory should follow the RCF Designer’s instructions and AB-036395.
9.6 RCF System Limitations:
- RCF systems have limitations, including velocity limits and restrictions in sections with sootblowers, steam lances, or water wash facilities.
- RCF systems should not be used when heavy metal fuel content exceeds 100 ppm.
Please note that the specific details and requirements may vary depending on the design and specifications provided by the RCF Designer.
FAQs about SAES-N-140 PDF Download
Q1: What are refractory materials?
A: Refractory materials are heat-resistant materials used in various industries to withstand high temperatures, resist corrosion, and provide insulation in furnaces, kilns, and other thermal processing equipment.
Q2: What are the common types of refractory materials?
A: Common types of refractory materials include fire clay bricks, high-alumina bricks, silica bricks, magnesia bricks, castables, and ceramic fiber products.
Q3: How are refractory materials installed?
A: The installation of refractory materials depends on the specific application. It can involve techniques such as casting, gunning, ramming, and bricklaying, depending on the form of refractory material used and the design requirements.
Q4: What factors should be considered when selecting refractory materials?
A: Factors to consider when selecting refractory materials include the maximum operating temperature, chemical composition of the process environment, thermal conductivity, abrasion resistance, thermal shock resistance, and cost-effectiveness.
Q5: How long does it take to cure refractory materials?
A: The curing time for refractory materials can vary depending on the type of material used, ambient conditions, and curing method. It can range from a few hours to several days.
Q6: Can refractory materials be repaired?
A: Yes, refractory materials can be repaired. Minor damages can often be repaired by patching or applying a new layer of refractory material. However, extensive damage may require complete replacement of the refractory lining.
Q7: What precautions should be taken during refractory installation?
A: During refractory installation, it is important to follow safety guidelines, wear appropriate protective equipment, ensure proper mixing and application techniques, and adhere to temperature and environmental requirements specified by the manufacturer.
Q8: How long do refractory linings typically last?
A: The lifespan of refractory linings can vary depending on factors such as operating conditions, type of refractory material, and proper maintenance. Generally, refractory linings can last anywhere from a few years to several decades.
Q9: Can refractory materials be recycled?
A: Some refractory materials, such as certain types of bricks and ceramic fibers, can be recycled. The recycling process involves collecting used refractory materials, crushing them, and incorporating them into new refractory products or other applications.
Q10: Where can I find detailed installation guidelines for refractory materials?
A: Detailed installation guidelines for refractory materials can be found in industry standards, manufacturer’s recommendations, and specific project specifications. Consulting relevant standards and seeking guidance from experienced refractory professionals is recommended for proper installation.
