Copper flanges: structure, advantages, disadvantages, and applications

Copper flange helps connect pipes and pipe fittings. Copper flanges are not as common as steel and stainless steel flanges but are still used in special projects. So what are copper flanges? What are their structures and specifications? Check out Bao Tin Steel’s article for a complete answer!

What is a copper flange?

Copper flanges are pipe fittings made of copper material (red copper, brass, etc.). They often connect pipes, industrial valves, pumps, etc. to form a complete piping system.

Copper flange is also known as copper flange and has the English name Copper Flange.

Currently, there are many types of copper flanges on the market. However, the most popular and widely used types are solid (blind) copper flanges, hollow copper flanges, etc.

Specifications of copper flange

• Manufacturing materials: brass, red copper,
• Size: DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300,
• Flange manufacturing standards: JIS, BS, ANSI, DIN,
• Working pressure: JIS 5K, 10K, 16K. 20K,… PN6, PN10, PN16, PN25,
• Working environment: domestic water, clean water,
• Origin: Vietnam, China, Japan,

Each flange standard will specify different diameters, thicknesses, bolt holes, etc. Therefore, you need to understand your project clearly and calculate carefully before choosing the right type of copper flange. Refer to the article on flange standards for more information!

Structure and application of copper flange

Similar to other common types of flanges, copper flanges will also include 3 basic components. Specifically:

1. Bolt Hole
2. Inside Diameter. This is the large space between the flanges
3. Outside Diameter. This is the distance between the two opposite edges of each flange.

Copper flanges have a wide range of applications in various industries, thanks to their features and advantages. Here are some common applications of copper flanges:

• In water treatment systems. Specifically, copper flanges are used in the installation of water pipes, clean water supply, and drainage, and domestic water in residential areas, public areas, factories, industries, etc.
• In the food industry. Copper flanges are used to connect pipes or equipment used for food processing and preservation.
• Used for installation with industrial valves. Such as copper ball valves, globe valves, copper gate valves, etc.
  In the energy industry. Copper flanges are used to connect pipes or equipment related to the production, transmission, and distribution of electricity, specifically generators, transformers, electric cables, etc.

Common types of copper flange

There are many types of flanges available in the market today due to the different service conditions we operate in. Copper flanges are one of the top choices of accessories. So do you know how many types of copper flanges there are? If not, read on!

Blind copper flange (solid)

Blind copper flange (also known as solid flange) is a type of flange without a hole in the middle. This product is used to seal pipes and equipment to stop the flow or change the flow.

Hollow copper flange

Unlike blind copper flanges, hollow copper flanges are the type with a hole in the middle. This product is used to connect pipes or equipment of the same diameter to maintain continuous flow and not change the direction of flow.

Copper flange

Flanged copper is a type of flange with a protruding flange in the middle (flanged surface), connecting the two flanges is a metal gasket. This product is often used in systems that require high tightness and can withstand high pressure.

Advantages and disadvantages of copper flanges

Advantage

• Copper flanges can be used in clean water, domestic water, etc.
• Diverse sizes. Copper flanges are manufactured in many different sizes, suitable for many pipelines. DN50-DDN800
• Flanges meet JIS, DIN, ANSI, BS standards, etc.
• Low cost. Copper flanges are cheaper than other types of flanges, specifically flanges made from carbon steel (steel flanges), stainless steel (stainless steel), etc.
• Efficient in installation and maintenance. Copper flanges can be installed, replaced, and maintained easily.

The copper flange has many outstanding advantages, however, it also has some disadvantages as follows:

Disadvantages

• Copper flange should be limited in chemical and highly corrosive environments.
• Slow connection, integration time required

Criteria for selecting suitable copper flange

Each type of flange will have parameters and characteristics to suit each system. And the same goes for copper flange. To choose the right copper flange for your pipeline, you need to understand the following criteria:

• Criteria 1. Choose the flange standard. Copper flanges have standards such as JIS, DIN, ANSI, BS, etc. If you choose the wrong standard, the flange cannot be connected to the pipe.
• Criterion 2. You need to determine what diameter the pipe is.
• Criterion 3. Choose the material for the flange.
• Criterion 4. Determine the flange connection type. For example, for threaded flanges, the most convenient welding type should be chosen.
• Criterion 5. You need to choose a blind flange, a hollow flange, or a flange with a flange, etc.
• Criterion 6. This criterion is equally important, which is to determine the size according to the technical specifications.
