Slip-on Flange

Short Description:

Application: Flanges are integral parts of many engineering and plumbing projects. Used in many, different fields, such as the transport (pipelines, ships) of petroleum, gas, water, etc., their manufacturing facilities and those of power generation, chemicals, and chemical fertilizers, flanges are of various kinds in type and shape, and their material too is diversified (low carbon steel, low alloy steel, stainless steel, high alloy steel, non-ferrous steel, or such) in accordance with the type of fluid and service environment.

Introduction: 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.

The SO flange can be divided into SO welding plate flange and SO welding hubbed steel pipe flange. Its mechanical characteristics are between the integral flange and the looping flange. The structure is simple, and the processing is convenient. So slip on flange welding is widely used in various fluid pipelines.

Depends on different face, there are also ranges raised face type and ring type joint face type.

In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. They do this by fastening two pieces of metal or other material together with a circle of bolts on a lip. This "lip" is a flange.

You can connect two sections of metal piping by soldering or welding them together, but pipes connected in this way are very susceptible to bursting at high pressures. A way of connecting two sections of pipe more securely is by having flanged ends that you can connect with bolts. This way, even if gases or liquids build up to high pressures inside the pipe, it will often hold with no problem.

Advantages of Slip On Flange
Lower installation costs
More easy to align with other parts during installation
Better leaking proof
​Inner and outer welding on flange
Takes less time to cut accurately for the pipelines
As pipe slides on the flange, it compatible with lower hub on slip on flange
