What is Slip On Flange
Slip On flange, also is called SO flange, it is usually connected to a pipe by one or two fillet welds (one outside the flange and one inside the flange), it is however possible to use only a single weld.
Class 150 Slip on flanges are a popular type of pipe flange designed to accept pipe into the bore/center of the flange for welding around both the Outer Diameter (OD) of the pipe and on the interior side of the connection.
It is convenient to install on site, it is the reason of so popular in the market.

Sealing Face for Slip On Flange
The raised face (RF) is the most common type of flange facing used. It is called a raised face flange because it has a raised surface above the bolting circle where the gasket is placed. These flanges are widely used in oil and gas pipelines.
Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat.
Ring type joint flange(RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened.
Pressure Rate of Slip On Flange
There are seven Classes - 150, 300, 400, 600, 900, 1500, and 2500. The rating indicates the maximum allowable pressure at a given temperature. For example, Class 150 slip on flange means the maximum pressure the flanges can bear is 150LB.
Application
They are mainly used for fluids at low pressure or with little risk of leakage. It is very common to find these flanges today in cooling water lines, firefighting water lines, low-pressure compressed air lines, and process lines for substances such as steam, oil, gas, condensates, etc. But always keeping in mind that the material to be distributed is at low pressure and the working conditions are not demanding.
Packing
For the size of 1/2" - 8", the package type is crate, and put the protector for each flanges
8" -12" is Pallet, and above 12" is loose.
However, the packaging can be customized according to the customer's specific requirements.
