ISO flanges are generally compatible with other flange standards (like ASME or ANSI) when proper adapters or transitioning components are used. However, it's crucial to ensure dimensional compatibility for a secure connection.
ISO flanges are standardized by the International Organization for Standardization (ISO), while ANSI and ASME standards are American-based. The key differences may include dimensional variations, pressure ratings, and material specifications based on regional standards.
