02-SAMSS-011Forged Steel and Alloy Flanges
The specification 02-SAMSS-011 is a comprehensive document that outlines the specific requirements set by Saudi Aramco for forged steel and alloy flanges. These flanges play a critical role in various industries, providing secure connections and leak-tight seals between piping components.
The scope of 02-SAMSS-011 encompasses a wide range of flange types, including standard configurations and special designs tailored for specific applications. Some of the special configuration flanges covered by this specification include:
- Pipeline Anchors: These flanges are designed to provide stability and support for pipelines, helping to prevent movement and displacement caused by external forces or environmental factors.
- Long Weld Neck Flanges: These flanges have extended necks, which allow for easy connection in applications requiring additional clearance or where insulation is necessary.
- Integrally Reinforced Flanges: These flanges are reinforced to withstand higher pressures, making them suitable for critical environments where the pipeline may experience significant stress.
- Out-size Flanges: These flanges are designed for use with larger pipe diameters and provide a secure connection for pipelines with non-standard dimensions.
- Lapped Joint, Swivel Ring Assemblies: These flanges allow for rotational movement, making them ideal for applications where the pipeline may experience thermal expansion or movement.
- Blind Flanges: These flanges are used to close the end of a pipeline or vessel, preventing the flow of fluids and providing a positive seal.
- Spectacle Plates, Blinds, and Spacers: These specialized flanges are used for specific maintenance or testing operations, allowing for temporary closure or isolation of pipeline sections.
However, it is essential to note that certain applications fall outside the scope of 02-SAMSS-011. The specification explicitly states that it does not apply to the following:
- Class 150 Low-Pressure Sanitary and Oily Water Services: This refers to flanges used in low-pressure applications related to sanitary services or pipelines carrying oily water. However, if these flanges are required for specific projects, they can be included by specifying them in the purchase order.
- Socket Weld and Threaded Flanges, and Type 6BX per API SPEC 6A: These specific types of flanges, as outlined in API SPEC 6A, are not covered by 02-SAMSS-011 and are subject to other standards and specifications.
In conclusion, 02-SAMSS-011 serves as a comprehensive guide for ensuring the quality, safety, and performance of forged steel and alloy flanges within the scope of its coverage. It includes a variety of flange types to accommodate diverse applications, but it excludes certain flange types and applications that are addressed in other standards or require specific project requirements.

FAQs about 02-SAMSS-011 of Forged Steel and Alloy Flanges
Answer: The specification covers a comprehensive range of flange types, including but not limited to pipeline anchors, long weld neck flanges, integrally reinforced flanges, out-size flanges, lapped joint, swivel ring assemblies, blind flanges, spectacle plates, blinds, and spacers.
Answer: Yes, the specification excludes Class 150 low pressure sanitary and oily water services, except when specified in the purchase order. Additionally, socket weld and threaded flanges, as well as Type 6BX per API SPEC 6A, are not covered by 02-SAMSS-011.
Answer: Special configuration flanges are designed to meet specific needs beyond standard flange types. For example, pipeline anchors provide stability and support for pipelines against external forces, while long weld neck flanges offer extended necks for easy connection in applications requiring additional clearance. Integrally reinforced flanges are reinforced to withstand higher pressures and ensure safety in critical environments. Each special configuration flange serves a unique purpose based on the specific requirements of the application.
Answer: Yes, the specification outlines detailed requirements for materials, fabrication techniques, and quality control to ensure the flanges’ durability, performance, and compliance with Saudi Aramco standards. Proper material selection is crucial to meet the specific demands of the intended application and ensure the flanges’ resistance to corrosion and mechanical stress.
Answer: While 02-SAMSS-011 provides comprehensive requirements for forged steel and alloy flanges, it may reference or work in conjunction with other relevant industry standards or specifications to ensure full compliance and compatibility with the intended use. It is essential to consider all relevant standards and specifications during the design, manufacturing, and installation processes to guarantee safe and reliable operation in the specific application environment.
