Threaded Flange

Threaded Flange(screwed flange)is similar to slip on flange while the bore is threaded. It is usually used in low pressure piping systems. The threaded flange is not suitable for a thin wall thickness pipe system. The threaded pipe used for steam service about 250 PSI or for water service about 100 psi with water temperatures above 220°F, the pipe should be seamless and have a thickness at least equal to SCH80 of ASME B36.10.
