Frequently Asked Questions

What is a slip-on flange?+

A slip-on flange has a bore slightly larger than the pipe OD, allowing the pipe to slide through. The pipe is then fillet welded on both the hub face and back of the flange. This design is simpler and less expensive than weld neck flanges.

When should slip-on flanges not be used?+

Avoid slip-on flanges in high-pressure applications above Class 300, severe cyclic service, or where radiographic examination of the weld joint is required. Weld neck flanges are preferred for these conditions.
