Slip On Flange

Fusion Fittings is a professional manufacturer of high-quality slip-on flanges in various specifications, grades, materials, and sizes. We specialize in producing slip-on flanges that conform to various dimensional standards, including ANSI/ASME B16.5, ANSI/ASME B16.47 A series (MSS SP-44), ANSI/ASME B16.47 B series (API 605), ANSI/ASME B16.36, and ANSI/ASME B16.48 (API 590). In addition to ANSI and ASME standards, we can also produce slip-on flanges according to EN, BS, and DIN standards.

What are Slip-on flanges?

Slip-on flanges are perhaps the most common type of flange in the industry and are an ideal choice for low-pressure applications. As the name suggests, slip-on flanges slide onto the pipe and are welded (usually on the inside and outside) to provide strength and prevent leakage. Slip-on flanges are on the lower end of the cost spectrum and do not require high precision when cutting pipes. These slip sleeves can sometimes have a raised face or a hub, which can be rough-bored to accommodate a hole that fits the pipe or tube. Its inner diameter is larger than the outer diameter of the pipe. These connections are joined to the pipe through fillet welds at the top and bottom of the flange.

Slip-on pipe flanges are used in conjunction with convex or flat surfaces. When convex, the standard height for pipe flanges below 400# is 1/16", and for 400# pipe flanges, the standard height is 1/4". Socket-welded pipe flanges include materials such as carbon steel socket-welded pipe flanges, stainless steel socket-welded pipe flanges, and alloy steel socket-welded pipe flanges, and can provide various ratings such as 150 LBS, 300 LBS, 600 LBS, and 900 LBS.

We can also produce reducing slip-on flanges. If there is a large slip-on (such as 12 inches) on the flange blank instead of cutting out (or drilling) a center (pipe) hole for a 12-inch pipe, it is cut out for a 6-inch (or other sizes) pipe. The slip-on on a reducing flange is basically used to reduce the size of the pipeline when using a combination of weld neck flanges and eccentric reducers that are restricted by space limitations. In cases where the flow direction goes from a smaller size to a larger size, a socket-welded reducing flange is usually the preferred option.
