ASME/ANSI B16.5 1500 Class Slip On Flange/Standards, Dimensions & Weight

Slip on flanges are designed to be slipped over the pipe and then welded, typically on both the inside and outside, to increase strength and prevent any potential leakage. Compared to other types of flanges, slip on flanges are relatively inexpensive and do not require a high degree of precision when it comes to cutting the pipe to the right length. Some slip on flanges may come with a boss or hub, and can be made with a bore that accommodates either a pipe or tube.
