SAES-N-130Refractory Bricks Installation Requirements
SAES-N-130 is a standard that outlines the minimum mandatory requirements for the installation, testing, and inspection of refractory bricks used in process equipment. Here are some key points about this standard:
- The standard applies to the installation and repair of refractory bricks in process equipment.
- For equipment and refractory systems not specifically covered by this standard, guidance from a Saudi Aramco Engineer should be sought to determine the applicability of this standard.
- The entire standard can be attached to contracts for brick installation, making it an integral part of the contractual agreement.
- The scope of this standard includes the installation of new refractory bricks as well as the repair of existing refractory bricks.
For detailed instructions and specific requirements regarding the installation, testing, and inspection of refractory bricks, it is recommended to refer to the full SAES-N-130 standard.
Installation
The installation requirements for refractory bricks are outlined as follows:
6.1: Expansion joints should be installed according to the refractory design specifications.
6.2: All brick linings must be supported as per the design drawings, and the refractory supports should be made of austenitic alloy material.
6.3: Brick linings should be supported by metal support shelves that are welded to the casing. The shelves should be spaced a maximum of 8 meters vertically and should be slotted to allow for differential thermal expansion. The temperature of the shelf metal should be selected based on the calculated maximum surface temperature plus 10°C.
6.4: The thickness of mortar between bricks should not exceed 2 mm.
6.5: The use of steel shims is prohibited for supporting the brick lining.
6.6: Bricks should not be cut and used below 50% of their original thickness or below 50 mm, whichever is greater. Additionally, two cut bricks should not be installed adjacent to each other.
6.7: Manual cutting or chipping of bricks is not allowed during the installation process.
6.8: Key bricks in adjacent rings should be staggered in their positions.
These requirements are important for ensuring proper installation and performance of the refractory brick lining. It is recommended to consult the full SAES-N-130 standard for comprehensive guidelines and additional details regarding the installation and repair of refractory bricks.
FAQs about SAES-N-130 PDF Download
What is refractory material?
Refractory material is a specialized heat-resistant material used to line high-temperature equipment such as furnaces, kilns, and reactors. It provides thermal insulation and protects the underlying structure from the extreme temperatures and chemical reactions involved in industrial processes.
Why is refractory material important?
Refractory material is essential for maintaining the integrity and efficiency of high-temperature equipment. It helps to contain heat, prevent heat loss, and protect the structural components from damage caused by thermal stress, chemical corrosion, and abrasion.
What factors should be considered during the installation of refractory material?
Several factors should be considered during installation, including temperature limitations, surface preparation, mixing ratios, curing and dryout procedures, selection of appropriate anchors and supports, adherence to manufacturer guidelines, and compliance with industry standards and regulations.
How should refractory material be mixed?
Refractory material should be mixed according to the manufacturer’s guidelines. It is typically mixed with a specific liquid, using suitable mixing equipment, such as a paddle type mixer. The mixing process should ensure a uniform and consistent mixture without lumps or dry spots.
How is refractory material applied?
Refractory material can be applied using various methods, such as hand packing, gunning, or shotcreting, depending on the specific application and design requirements. The material is carefully placed and compacted to form a solid and well-adhered lining.
What is the curing process for refractory material?
The curing process involves allowing the refractory material to dry and harden to achieve its desired strength and properties. It may involve controlling the ambient temperature, applying moisture, or using curing compounds as per the manufacturer’s recommendations.
How long does it take for refractory material to cure?
The curing time can vary depending on factors such as the type of refractory material, ambient conditions, and the specific application. It is important to follow the manufacturer’s guidelines regarding the recommended curing time and procedures for optimal results.
What is the dryout process for refractory material?
The dryout process involves gradually heating the refractory lining to remove any remaining moisture and ensure its stability at high temperatures. It is typically performed in a controlled manner, following specific temperature profiles and duration as specified by the manufacturer or industry standards.
Can refractory linings be repaired?
Yes, refractory linings can be repaired if damaged or worn out. Repair methods may include patching, relining, or adding supplementary layers of refractory material. It is important to follow proper repair procedures and consult the manufacturer or a qualified refractory specialist for guidance.
Why is it important to follow installation guidelines and standards?
Following installation guidelines and standards is crucial for ensuring the optimal performance, longevity, and safety of refractory linings. Adhering to these guidelines helps to maintain the integrity of the lining, prevent premature failure, and ensure compliance with industry regulations and best practices.
