ASME B16.21 – 2021 Edition – Nonmetallic Flat Gaskets for Pipe Flanges
ASME B16.21-2021 is a standard published by the American Society of Mechanical Engineers (ASME) that addresses non-metallic flat gaskets for pipe flanges. This standard specifies dimensions, tolerances, materials, and marking requirements for non-metallic flat gaskets used in raised-face and flat-face flanges in pressure piping systems.
Here’s an overview of ASME B16.21-2021:
- Scope: The standard specifies requirements for non-metallic flat gaskets suitable for use with raised-face and flat-face flanges in pressure piping systems.
- Dimensional Requirements: It provides dimensional requirements for gasket thickness, outside diameter, inside diameter, and other relevant dimensions.
- Tolerances: ASME B16.21-2021 specifies tolerances for various dimensions of the gaskets to ensure proper fit and sealing.
- Materials: The standard covers the materials that may be used for non-metallic flat gaskets, including elastomers, compressed non-asbestos fiber materials, and other suitable materials.
- Marking: It outlines requirements for marking the gaskets to indicate compliance with the standard and provide traceability.
- Applications: ASME B16.21-2021 is applicable to gaskets used in a wide range of industries and applications where non-metallic gaskets are preferred or required for sealing pipe flanges.
- Revision: The “2021” in the standard’s title indicates that it was last revised in that year, ensuring that it reflects the latest industry practices and advancements.
Overall, ASME B16.21-2021 provides guidelines for the manufacture and use of non-metallic flat gaskets in pressure piping systems, helping to ensure proper sealing and integrity in various industrial applications.
