What is a companion flange?

: a pipe flange threaded internally to receive a pipe length and drilled so it may be bolted to another like flange sometimes : a similar arrangement for coupling two parts of a shaft.

What is a threaded companion flange?

– A Companion Flange is a flange that has a hub that is either socket or threaded that you would attach to your pipe.

What is a threaded flange?

Threaded flanges, also sometimes referred to as companion flanges / screw flanges / NPT flanges, contain a female NPT thread in the center for connection to male NPT threaded piping. The male pipe end is joined to the flange without a weld connection required but can be sealed with a weld if necessary.

Where is the companion flange?

What is the purpose of companion flange?

A companion flange, sometimes referred to as a hub, allows connection of a flange yoke to another type of connection, for proper torque transfer.

What is a tapped blind flange?

These include NPT tapped holes and special threads to allow pressure test connections to be fitted. Blind flanges are generally used to blank off the ends of pipe. They are also used on similar valves and pressure vessel openings.

What is a flange used for?

Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. A cover plate can be connected to create a “blind flange”. Flanges are joined by bolting, and sealing is often completed with the use of gaskets or other methods.

How are flanges classified?

Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). Metal flanges are classified from 150 to 2500 # rating.

Is a flange considered a fitting?

Pipe Flanges are widely used as a popular category of pipe fittings. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface.

How does a companion flange work?

A companion flange is a flange that corresponds to another flange. Having bolt holes that align with another flange is a trait of this type of flange. It allows connection of a flange yoke to another type of connection, for proper torque transfer.

When do you use a companion flange in a pipe?

The companion flange is an important component of a pipeline or a plumbing system. In most situations, this flange is attached to the flange of another pipe and then the pipeline is assembled to fit tightly between the two flanges. A threaded companion flange is also used on a plastic pipe when adding a threaded iron pipe into the pipeline.

What kind of thread is in a threaded Flange?

Threaded flanges, also sometimes referred to as companion flanges / screw flanges / NPT flanges, contain a female NPT thread in the center for connection to male NPT threaded piping. Threaded flanges are common when creating reducing connections.

What are the different types of reducing flanges?

Reducing flanges are attached by welding, gluing or clamping flanges of the same size supplied with different connecting pieces. Threaded flanges look nearly identical to Slip-On flanges but the key difference is that the threaded flange has been bored out to match the inside diameter of a particular pipe.

What do you need to know about a flange connection?

At its most basic level, a flange connection involves joining two pieces of material together by means of an internal or external lip. A gasket gets fitted between that pair of pieces to prevent any leakage.

A companion flange is a flange that corresponds to another flange. Having bolt holes that align with another flange is a trait of this type of flange. The companion flange is an important component of a pipeline or a plumbing system.

What is a flange connection system?

What is a flange connection system? Flanges are the parts that connect the shaft to the shaft and are used for the connection between the pipe ends. They are also used for flanges on the equipment inlet and outlet, for the connection between two devices, such as the reducer flange.

What is a connector flange?

A flange connector is a device that allows the connection of many types of hoses and fittings onto a flanged pipeline. Typically manufactured from stainless or high- carbon steel, a flange connector is connected to a flanged pipe with bolts, and a gasket is sandwiched between the pipe flange and the connector.

What is a valve flange?

A flange valve is a particular type of valve where a raised surface, usually in the shape of a lip or ring on the end of the valve fitting, is mated to a groove on the facing to which it attaches. This gives the valve connection increased strength in heavy-duty piping such as for that used in the chemical and petroleum industries.
