Dimensions of Class 600 Female Ring-Joint Facing Figure-8 Blanks
Class 600 Female Ring-Joint Facing Figure-8 blanks are specialized components designed for use with Class 600 Ring-Joint (RJ) flanges. These blanks are used primarily to isolate sections of piping systems, particularly in high-pressure environments where sealing is critical. The Figure-8 shape of the blank ensures it fits precisely into the female ring-joint groove of the flange, creating a secure, leak-proof seal even under higher pressures (up to 600 psi).
The Class 600 designation refers to the pressure rating of the flange system, which is commonly found in oil & gas, chemical processing, and power generation applications. These blanks provide a cost-effective and reliable way to isolate pipelines during maintenance, testing, or when shutting down certain pipeline sections.

Key Features of Class 600 Female Ring-Joint Facing Figure-8 Blanks:
Figure-8 Shape: The Figure-8 design of the blank is tailored to fit into the female ring-joint groove of a Class 600 flange. This unique shape allows for an efficient, tight seal, preventing leakage even in high-pressure systems.
Material Composition: Class 600 blanks are typically constructed from carbon steel, stainless steel, or alloy materials to ensure they can withstand the higher pressure ratings and harsh operating conditions of Class 600 systems.
Materials are chosen for their strength, durability, and resistance to corrosion, ensuring they can handle the demands of high-pressure and high-temperature environments.
Sealing Performance: Class 600 blanks are designed for systems that operate at pressures up to 600 psi. The Figure-8 design helps create a strong seal, even in applications with fluctuating or extreme pressure conditions.
Applications:
- Pipeline Isolation: These blanks are ideal for isolating specific sections of a pipeline during maintenance, shutdowns, or inspections, ensuring that the rest of the system remains operational.
- High-Pressure Systems: Primarily used in oil and gas, chemical, and power generation industries, Class 600 systems are designed to handle more demanding operational conditions than lower-rated systems.
- Maintenance and Repairs: Used to temporarily block or isolate pipeline sections, these blanks prevent flow and allow for repairs or inspections without interrupting the entire pipeline system.
- Shutdowns and Emergency Isolation: Class 600 blanks are useful for quick shutdowns and emergency isolation in high-pressure environments, preventing leaks or accidents.
Compatibility: These blanks are designed specifically for Class 600 Ring-Joint flanges, ensuring perfect alignment with the female facing and groove profile of the flange. This ensures a secure, leak-proof fit when the blank is installed.
Bolt Hole Alignment: The bolt holes of the blank are aligned with the bolt circle of the Class 600 Ring-Joint flange. This ensures easy and secure installation using appropriate bolts for Class 600 flanges, minimizing the risk of improper attachment and ensuring a reliable seal.
Advantages of Using Class 600 Female Ring-Joint Facing Figure-8 Blanks:
- High-Pressure Sealing: Designed for Class 600 pressure-rated systems, these blanks ensure reliable sealing in high-pressure environments, maintaining the integrity of the pipeline system.
- Durability and Strength: Made from high-quality materials such as carbon steel or stainless steel, these blanks offer exceptional durability and can withstand the stresses of high-pressure applications.
- Leak-Proof Performance: The Figure-8 design creates an effective seal, reducing the risk of leakage and ensuring the system remains isolated and secure during shutdowns or maintenance.
- Versatile Use: Ideal for a variety of industries, including oil and gas, chemical processing, petrochemical, and power generation, where isolation of pipeline sections under high-pressure conditions is necessary.
- Cost-Effective: Figure-8 blanks provide an affordable solution for maintaining system integrity and isolation during scheduled or emergency shutdowns without the need for more complex isolation methods.
Applications:
Pipeline Isolation: Class 600 Female Ring-Joint Facing Figure-8 blanks are frequently used to temporarily isolate specific sections of a pipeline, particularly when maintenance or repairs are needed on part of the system.
Shutdowns and Maintenance: These blanks are especially useful for shutdowns or emergency isolation where a high-pressure pipeline section needs to be sealed off quickly and effectively.
Sealing in High-Pressure Systems: Ideal for use in high-pressure pipeline systems, including oil & gas, chemical, and power generation industries, where safe, reliable sealing is a must to prevent leaks and maintain system integrity.
Class 600 Female Ring-Joint Facing Figure-8 blanks are integral components in high-pressure pipeline systems, providing secure isolation and leak-proof sealing when used with Class 600 Ring-Joint flanges. Their Figure-8 design ensures a perfect fit and reliable seal, making them ideal for high-pressure systems found in industries like oil and gas, chemical processing, and power generation. These blanks offer a durable, cost-effective solution for pipeline isolation during maintenance, repairs, and emergency shutdowns.
