A slip-on flange is a mighty popular type of pipe flange built to take the pipe right into the bore or center of the flange. Then y'all just weld around both the Outer Diameter (OD) of the pipe and on the inside of that connection.
Dat slip-on flange is a simple and mighty fine alternative to a weld neck since it don't have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position on the flange.
The bore of dat slip on is gonna give y'all an ample amount of space for the matchin' pipe. This allows for enough workin' space for the welder and fabricator to make dat connection right.
This flange type is mighty common in lower pressure jobs. Most slip on style flanges will have a hub that looks a lot like a raised face dimensionally. We can furnish it without a hub if space is tight and your job allows for a “ring style” slip on.
Slip ons in them higher pressure classes are often made with the height of a lap joint to give y'all a better connection. If that hub height ain't a worry and a lap joint ain't easy to find, folks will sometimes just go with a slip on made to a lap joint style with a machined hub.
This is 'cause a slip on style flange will take a pipe with a fillet weld connection, while a weld neck flange has a reinforced hub at the base and forms a weld bevel connection straight to the butt weld end of a pipe. Dat tapered hub gives y'all stronger service when things get mechanically stressful.

Slip-on Flanges
Types of Slip-On Flange Weldin' Slip-on (SO) flanges come in two main types: SO weldin' plate flanges and SO weldin' hubbed steel pipe flanges. Dese flanges balance integral and lap joint flanges with a straightforward design and easy processin'. Consequently, slip-on flange weldin' finds extensive applications in all sorts of fluid pipelines.
Raised Face Slip-On Flange
Dat raised face slip-on flange features a small protrusion right on its bottom face. This raised face serves as a designated spot for gasket placement durin' installation, enhancin' the overall sealin' performance.
RTJ Slip-On Flange
In the case of RTJ slip-on flanges, a small groove is precision-machined right on the raised face section. This here unique RTJ design is intended explicitly for high-pressure applications, givin' a mighty fine groove for gasket ring placement and makin' sure you get superior sealin' compared to dat RF type.

Questions Folks Ask Us (FAQs)
A slip-on flange is a kind of pipe flange dat slides right over the pipe's end and gets bolted down tight through dem pre-drilled holes.
It's designed with a slightly larger bore than the pipe to let it "slip on" right easy before fastenin'. It's commonly used in low to medium-pressure systems, yessir.
The design allows for quick assembly without the need for complex weldin' or alignment, makin' 'em mighty ideal for projects where time is a factor.
Slip-on flanges usually run a bit cheaper than other flanges, like weld-neck or blind flanges, 'cause their design and the way we make 'em is a whole lot simpler.
Now dese flanges ain't built to handle high-pressure or high-temperature systems, so they're just right for your standard jobs where pressure ain't no big concern.
Now when your budget is tight and the job don't need the heavy-duty strength of dem pricier flanges, slip-on flanges are a mighty cost-effective way to go.
Now, slip-on flanges ain't built for them high-pressure systems, and they might just fail or start leakin' if the pressure gets too extreme.
The design of the slip-on flange don't provide the same resistance to vibration as other flange types, like welded or socket weld flanges, which can lead to connection failure over time.
Make sure the end of dat pipe and the inside of the slip-on flange are clean of any debris. Slide dat slip-on flange right over the pipe end. The flange oughta fit snug, but y'all shouldn't have to force it.
Just spin that flange around till the bolt holes line up right nice with the holes on your pipe or fittin'. Then go on and slip the right bolts through them holes.
Tighten dem bolts in a criss-cross pattern to evenly distribute the pressure and get y'all a proper seal.
