01 What is the difference between a threaded flange and a slip-on flange?

A threaded flange connects to pipes with external threads without welding, while a slip-on flange requires the pipe to be inserted and then welded both inside and outside for secure attachment.
The common types include raised face (RF) and flat face (FF). Raised face flanges provide a better seal with gaskets due to the small raised surface.
Yes, threaded flanges can have different threading standards, such as NPT (National Pipe Thread) and BSP (British Standard Pipe).
