What is a companion flange used for?

Companion flanges are essential in pipe works and related equipment to quickly assemble and disassemble connected components. Notably, most flanges used in oilfield operations have bolt-hole patterns to secure the joints and a gasket to provide a pressure-tight seal. So, it makes repair and maintenance effortless.

What is a connection flange?

What Is 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. Then installers generally use bolts to seal them tight.

How are flanges attached to pipes?

Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.

What is the difference between a blind flange and companion flange?

Overview. A Companion Flange is a flange that has a hub that is either socket or threaded that you would attach to your pipe. In the other hand, a Blind Flange is solid in the middle and you would bolt to a companion flange to terminate a line. This type of flange does not have a hub.

What are the two main types of flanges?

Different Types of Flanges and Their Uses

• Weld Neck Flanges.
• Slip-on Flanges.
• Threaded Flanges.
• Blind Flanges.
• Socket Weld Flanges.
• Orifice Flanges.

What are the different type of flanges?

Types of flanges

• Slip-on flanges. The slip-on flange is a ring (with or without a hub) placed over the pipe’s end.
• Weld neck flanges. Weld neck flange is also known as a high-neck flange or tapered hub flange.
• Socket weld flanges.
• Blind flanges.
• Lap joint flanges.
• Threaded flanges.

What are the two main types of flanges available?

We usually consider two main families of flanges, the standard flanges and the special ones.

What is a boss flange?

These allow the flange to slide over the pipe and are joined to the pipe with a fillet weld at the top and the bottom of the flange. A bossed type has a reinforcing disc around the outside of the pipe which helps support the pipe making for a stronger joint. Usually machined from forgings for strength.

What are banana wedges used for?

These tools are often used for lifting and aligning machinery or to separate pipe flanges. They’re also known as banana wedges. When used with a tether (not included), wedges with a tether hole help keep tools close and prevent them from accidentally falling.

What are banana wedges?

H & M ‘s Banana Wedges (Part # BWEDGE) are made of forged Carbon Steel for durability and designed to facilitate the separation of pipe flanges. Two opposing wedges are driven together, forcing flanges to separate (see photo B)

What is a companion flange?

A Companion Flange, sometimes referred to as a hub, is a flange that corresponds to another flange. It has bolt holes that align with another flange is a trait of this type of flange.

What is the best material for plumbing fittings?

They are often used in drinking water and plumbing applications. Brass and bronze are compatible and can be used interchangeably. Aluminum has good corrosion resistance and is lightweight. Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings.

Are bronze and stainless steel pipe fittings interchangeable?

They are compatible and can be used interchangeably. Stainless steel has very good to excellent corrosion resistance. Brass and bronze have good corrosion resistance. They are often used in drinking water and plumbing applications. Brass and bronze are compatible and can be used interchangeably.
