What is slip on flanges?

Slip On Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the backside of the flange.

Where slip on flanges are used?

Slip on flanges are suitable for low-pressure applications and are easy to install and weld onto different pipes. In addition, welding helps to reduce manufacturing costs. Slip-on flanges do not require a large longitudinal space in the line to be mounted.

How are slip on flanges welded?

Slip-on fittings slip onto the end of the pipe. The flange is then welded around the contact points on the inside and outside of the pipe and the flange. Slip-on flanges are not considered as strong a joint as weld-neck or butt-welded connections.
