Product Description

A particular kind of flange called a duplex flange is built of a duplex alloy, which combines austenitic and ferritic stainless steels. This alloy has a special mix of qualities that make it perfect for use in a variety of applications in the chemical, oil and gas, and maritime sectors, including high strength, great corrosion resistance, and exceptional weldability.

There are several types of duplex flanges available, including slip-on, weld-neck, threaded, blind, and socket-weld flanges. These flanges vary in size, shape, and connection method. Based on the particular needs of the application, such as pressure rating, temperature, and fluid compatibility, these flanges are chosen.

Depending on the needed dimensions and mechanical properties, duplex flanges are created using various production procedures such hot forging, cold forging, and machining. Additionally, they can undergo heat treatment to enhance their mechanical characteristics and produce particular microstructures like ferrite or austenite.

The application requirements, the necessary mechanical properties, the dimensions, the flange type, and the connection method should all be taken into account when choosing duplex flanges. It is advised to seek advice from a reliable manufacturer or supplier to make sure the selected item satisfies the demands of the application. To further guarantee the safety and dependability of the flange, suitable installation techniques and torque recommendations must be followed.

1. What is a duplex flange, exactly?

Ans - A duplex flange is a kind of pipe flange that combines two similar faces. It is frequently applied in situations where two pipe sections are linked and a secure, dependable seal is needed.

2. What benefits come with employing a duplex flange?

Ans - Compared to other flange types, duplex flanges provide a lot of benefits. They are simple to install and maintain, and they offer a reliable, leak-proof seal. They are superior to other kinds of flanges in terms of durability, which makes them perfect for high-pressure and high-temperature applications.

3. What kinds of materials go into creating duplex flanges?

Ans - Cast iron, stainless steel, or other metal alloys are frequently used in the production of duplex flanges.

4. How is the pipe connected to the duplex flanges?

Ans - Bolts, screws, or other attaching devices are frequently used to attach duplex flanges to the pipe.

5. What varieties of duplex flanges are there?

Ans - Duplex flanges come in a variety of styles, including threaded, welded, and slip-on flanges. According to the particular use, the appropriate type of flange should be selected as each has advantages and disadvantages of its own.
