Stainless Steel 347 Flanges Supplier

Stainless Steel 347 Flanges are critical components in various industrial applications, known for their exceptional corrosion resistance and high-temperature strength. These flanges are primarily composed of Stainless Steel 347, a stabilized austenitic stainless steel alloy that contains chromium, nickel, and columbium. They are designed to provide robust connections in piping systems, ensuring leak-free and reliable performance, even in harsh environments.

Key features of Stainless Steel 347 flanges:

Corrosion Resistance: Stainless Steel 347 is highly resistant to intergranular corrosion, making it an ideal choice for applications involving exposure to corrosive chemicals and high-temperature oxidation.

High-Temperature Strength: These flanges can withstand elevated temperatures, making them suitable for applications where other materials might degrade or lose their structural integrity.

Weldability: Stainless Steel 347 is easily weldable, allowing for strong and secure connections, ensuring the integrity of the entire system.

Durability: Flanges made from Stainless Steel 347 are known for their long service life and low maintenance requirements, reducing downtime and replacement costs.

Applications of Stainless Steel 347 flanges:

Petrochemical Industry: These flanges are commonly used in the petrochemical sector for connecting pipelines and equipment that handle high-temperature and corrosive materials.

Chemical Processing: They are ideal for chemical processing plants where resistance to corrosive substances is crucial.

Power Generation: Stainless Steel 347 flanges are used in power plants for connecting high-temperature steam and gas pipelines.

Aerospace: Their high-temperature strength and resistance to oxidation make them suitable for aerospace applications.

Food and Pharmaceutical Industries: Stainless Steel 347 is a favored choice in industries that require sanitary and corrosion-resistant components.

Types of Stainless Steel 347 flanges:

Weld Neck Flanges: These flanges have a long, tapered hub that provides an excellent connection to pipes and equipment. They are preferred for high-pressure and high-temperature applications.

Slip-On Flanges: These are easy to install and are suitable for low-pressure systems. They slip over the pipe and are then welded in place.

Blind Flanges: Used to close off the end of a piping system, these flanges do not have a bore.

Socket Weld Flanges: These are designed for smaller-sized pipes and offer good alignment and structural support.

Lap Joint Flanges: These flanges are used when the system requires frequent dismantling or where alignment is essential.
