DETAILED INFORMATION
Purohit Pipe Industries manufactures, supplies, and exports Duplex Steel Forged Flanges of the highest quality. With a wide range of dimensions, specifications, shapes, and sizes available, we offer an exclusive collection of Flanges. With our company, our clients can choose between custom and non-custom Duplex Steel Flanges. The corrosion resistance of Duplex Steel is superior to that of other alloys in most environments. In addition, chlorine-related stress cracking is not a problem with this material. It has a super finish and a robust quality that makes it an excellent choice for flanges. Our Flanges are widely used in industries such as pulp and paper, mining, chemical processing, marine applications, construction, and many others.
A Duplex Steel Slip Flange’s strength is enhanced by the austenitic portion of its structure, whereas its toughness is enhanced by the ferritin portion. Our company offers Duplex Steel Flanges with excellent performance due to their versatile features. Chromium is present in the chemical composition of these flanges, which contributes to their high surface toughness. Its versatility is enhanced by the super finishing and robust construction.
The product works very well in areas with high temperatures. We offer Duplex Steel Flanges that are readily fabricated and easily machined. To meet the urgent demands of the industry, we keep bulk stock of Duplex Steel Flanges.
Purohit Pipe Industries fabricates these Duplex Steel Flanges from premium quality raw materials that are tested again for quality once they are purchased in the manufacturing facility. In our production plant, we have installed the latest technology and hi-tech machinery. In order to ensure that the manufacturing process runs smoothly, we have hired a team of professionals. In order to provide the best quality Duplex Steel Flanges, we follow set standards of national and international standards. Our Duplex Steel Flanges are tested destructively and non-destructively based on various parameters. Purohit Pipe Industries uses standard packing methods for packing the flanges ordered. Duplex Steel Flanges are delivered to our esteemed clients within a specified timeframe.

Advantages of Duplex Steel Forged Flanges
Among the benefits of duplex steel forged flanges are:
-
- High strength and toughness: Duplex steel is known for its strength and toughness, making it especially suitable for applications involving high temperatures and pressures.
- The corrosion-resistant properties of duplex steel make it an ideal material for use in harsh environments, including pitting and crevice corrosion.
- For the fabrication of flanges and other components, duplex steel is a popular choice as it is relatively easy to weld.
- Duplex steel is often more cost-effective than other high-performance alloys, making it an attractive option for many applications despite its superior properties.
- A wide range of applications can be met by duplex steel forged flanges, including chemical, petrochemical, and oil and gas operations.
- Due to their high strength and corrosion resistance, duplex steel forged flanges have a long service life, making them a durable and reliable choice for critical applications.
Disadvantages of Duplex Steel Forged Flanges
There are certain advantages to using duplex steel forged flanges, but they also have some disadvantages to consider, including:
- Duplex steel is more expensive than some other materials, which can make it unattractive for some applications.
- Challenges in fabrication: Duplex steel requires specific manufacturing processes and may be more difficult to forge, machine, and weld than other materials.
- Temperature sensitivity: Duplex steel is sensitive to hot temperatures, which can affect its mechanical properties and make it more susceptible to stress corrosion cracking.
- There is a potential for embrittlement of duplex steel if not properly treated during fabrication or exposed to certain environmental conditions.
- In contrast to other materials, duplex steel isn’t readily available, which makes it harder to source and may have longer delivery times.
A material selection should consider these factors when selecting the appropriate material for the application to make sure that the benefits outweigh the disadvantages.
