Slip on flange, also called SO flange. It's a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.


Forged flanges combine two separate machinery parts together. They can be an extension to a structure in order to make the object stronger. Industrial flanges have numerous uses including connecting sheets, pumps, pipes and structures that specifically require an intermediate point of connection.

Applications of slip-on flanges

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.

Technology and Method of Forging Steel Flange

Its technology and method includes free forging, die forging and fetal membrane forging. According to the quality of the forgings and number of production batches, different forging methods are selected.

Free Forging

The free forging productivity is low, the machining allowance is large, but the tool is simple and the versatility is large, so it is widely used for forging a single piece and a small batch of forgings with a simple shape.

Die Forging

The die forging is collectively referred to as model forging, in which the heated blank is placed in the forging die fixed on the die forging equipment.

Forged Steel Flange

It has good streamline shape and compact structure, have good mechanical properties.

If the forging process is improper, the grain will be large or uneven, and the hardening crack will occur.

Forgings is compatible with high shear and tensile forces.

The internal structure of the forging is uniform.
