Frequently Asked Questions

What API standards apply to pipe flanges?+

API 605 covers large-diameter flanges for low-pressure applications, while API 6A covers wellhead flanges for high-pressure upstream service.

Can API flanges be used with ASME flanges?+

API 605 flanges have different bolt patterns and dimensions than ASME B16.47 flanges and are generally not interchangeable. Always verify compatibility before mixing standards.
