Below is a comprehensive Ring Joint Flange weight chart to help engineers, buyers, and suppliers make informed purchasing decisions.
What Are Ring Joint Flanges?
Ring Joint Flanges (RTJ flanges) are primarily used in applications that require enhanced sealing performance under extreme pressure and temperature. Commonly manufactured in stainless steel, alloy steel, or carbon steel, these flanges are ideal for refineries, chemical plants, and marine applications. They conform to international standards like ASME B16.5 and API 6A.
