Flange Dimensions & Gasket Chart
This flange and gasket reference table has been created to give engineers, specifiers, and maintenance teams a clear, practical guide to common flange standards across the most widely used pressure classes. Rather than separating data by valve size into multiple charts, this single master table allows you to compare ANSI, BS10, and BS4504 flange patterns in one place.
By using the “Valve Size” column, the same structure can be extended from 1/2" / DN15 right through to 24" / DN600, making it easy to scale this reference for any project – from small bore process lines to large diameter transmission systems. Each row details flange diameter, pitch circle diameter (PCD), bolt quantity and size, along with typical gasket thicknesses for cast iron, copper alloy, and steel applications.
This format is designed to reduce errors during specification, ordering, and maintenance, ensuring compatibility between valves, pipework, and gaskets across mixed-standard installations.

Use this table as a fast-reference tool when selecting valves, gaskets, and bolting for new installations, upgrades, or maintenance work. It is particularly useful in environments where ANSI and British standards are used side-by-side, helping to prevent costly mismatches and on-site delays.
Always verify final dimensions against the relevant standard or manufacturer’s datasheet for critical applications, especially in high-pressure or safety-critical systems. This guide is intended to support day-to-day engineering decisions, streamline procurement, and provide a single source of truth for flange and gasket compatibility across your projects.
