Stainless Steel 347 and 347H
Flanges are vital components in various industrial applications due to
their exceptional corrosion resistance and high-temperature performance. These flanges are
primarily composed of iron, chromium, and nickel, with the addition of niobium and tantalum
in 347H, which enhances its high-temperature capabilities. Here, we'll explore the key
features and applications of Stainless Steel 347/347H flanges in a concise 350-word
overview.
Key Features:
Corrosion Resistance: Stainless Steel 347/347H flanges are renowned for
their resistance to corrosion, making them ideal for applications where exposure to
corrosive environments is a concern. They can withstand acids, alkalis, and other harsh
chemicals, making them suitable for the chemical and petrochemical industries.
High-Temperature Strength: These flanges offer impressive high-temperature
strength, making them suitable for applications in elevated temperature environments such as
heat exchangers, boilers, and furnace components.
Durability: Stainless Steel 347/347H flanges have a long service life due to
their exceptional durability. They are resistant to heat-induced sensitization, ensuring a
prolonged life span in high-temperature applications.
Weldability: These flanges are easily weldable, facilitating their
installation and integration into various systems. Their weldability ensures a secure and
leak-free connection.
Applications:
Chemical and Petrochemical Industries: Stainless Steel 347/347H flanges are
widely used in the chemical and petrochemical sectors due to their resistance to corrosive
substances. They are employed in the construction of pipelines, storage tanks, and reaction
vessels.
Power Generation: In power plants, where high temperatures and pressures are
prevalent, these flanges find use in the construction of steam boilers, superheaters, and
other components that require excellent high-temperature strength and corrosion resistance.
Aerospace: Stainless Steel 347/347H flanges are used in the aerospace
industry for applications such as manufacturing combustion chambers, exhaust systems, and
other components that must endure extreme temperature fluctuations.
Food Processing: Their resistance to corrosion and ability to maintain the
purity of processed materials make these flanges suitable for food processing equipment,
ensuring the highest quality and safety standards.
Oil and Gas Industry: In the oil and gas sector, Stainless Steel 347/347H
flanges are employed in the construction of pipelines, wellhead equipment, and offshore
platforms where exposure to harsh and corrosive environments is common.
Manufacturing Process Of Stainless Steel 347 Flanges
Raw Material Selection
The manufacturing process of flanges begins with the careful selection of
raw materials.
Cutting and Shaping
Once the raw materials are selected, they undergo a precise cutting and
shaping process.
Finishings and Coatings
Coating the materials to a specific temperature ensures they become
malleable, facilitating the shaping process.
Welding and Joining
These processes ensure secure and leak-proof connections, enhancing the
reliability and longevity.
Finishing and Quality Control
After this the buttweld fittings undergo comprehensive finishing and
quality control procedures.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful
packaging techniques.
