- Slip On Flanges Uses
The Slip On Flange(SO Flange) is a kind of pipe flange, which is constructed in such a way that it can easily slide over the end of a pipe due to the inner diameter being slightly bigger than the outer diameter of the pipe. This is one of the most convenient and economical designs that can be easily aligned prior to welding and hence, it is used in piping systems. The slip-on flange connection is normally welded internally and externally giving it an excellent connection that is leak free as well as strong.
Their design does not require accuracy of cuts and beveling of pipes, which makes them applicable to those projects that require flexibility and speedy construction. Slip-on flanges are offered in raised face and ring-type constructions and are commonly used in the oil and gas industry, petrochemical industry, power generation sector, water treatment, or shipbuilding sector. Slip-on flanges are also used in preference to weld neck flanges due to their cost-saving nature and their need to cut less precision when joining the pipe to a length.

Slip On Flanges Welding
There is no tool in the welding of slip-on flanges: the flange is simply slipped over the pipe until the position is reached. The flange face must be made to hit the pipe end flat at the end and slightly above (not more than 1/16 of the wall thickness of the pipe). After a positioning, a single fillet weld or a double fillet weld is used to secure the flange. Where there is a double weld, both the inner and the outer weld are welded to provide a leakless and strong connection. The process offers a robust, dependable joint that can be used in the piping systems with low and medium pressure.

Slip on Flanges Types
The flanges come in a different design to suit different industrial needs and operating systems. Each of these flanges comes with different alignment and performance. All types of slip-on flanges information is given below.
Raised Face Slip-On Flanges
The very common type of flange is a Raised Face slip-on Flange whose surface is round for the placement of a gasket. It’s made with the qualities of leak resistance and can easily survive in moderate temperature and pressure applications.
Flat Face Slip-On Flange (FF SO Flange)
This flange has a smooth and flat surface with no raised face. It’s made with cast iron and fiberglass pipe to ensure the proper pressure distribution and prevent flange distortion.
Lap Joint Slip-On Flange (LJ SO Flange)
The lap joint slip-on flanges are made with backing flanges, easy rotation, and alignment. This makes it suitable for industries that require frequent assembly and maintenance.
Ring Type Joint Slip-On Flange (RTJ SO Flange)
These flanges are made up with a machine’s groove for a metal ring gasket. The oil and gas industry uses these flanges to manage high-pressure and high-temperature environments.
Slip-On Flanges Price
The price of the Slip-On flags depends on many factors, such as size, pressure rating, and specification. Usually, carbon steel slip-on flanges are cheaper than other flanges because they have more resistance to corrosion and durability, like stainless steel and alloy steel.

FAQs
1.What are slip-on flanges?
Slip-on flanges (SO flanges) slide over pipe ends and are welded inside and outside for a secure seal. They’re cost-effective, ideal for lower pressure applications, and available in materials like carbon steel, stainless steel, and alloy steel for simple installation and reliable performance.
2. What is the difference between a slip on flange and a threaded flange?
A slip-on flange slides over the pipe and is welded, while a threaded flange has threads on its inner bore to directly screw onto a threaded pipe end.
3. What is the typical pressure rating of a slip-on flange?
Slip-on flanges typically have pressure ratings ranging from 150 to 2500 pounds per square inch (PSI), depending on their size and material.
