Key Features:
Corrosion Resistance: The hallmark feature of Stainless Steel 904L is its unparalleled resistance to a variety of corrosive agents, including sulfuric acid, phosphoric acid, and chloride-rich environments. This resistance ensures the longevity of flanges even in harsh conditions.
High Nickel and Molybdenum Content: The high nickel and molybdenum content in 904L contributes to its exceptional corrosion resistance and durability. This makes it suitable for applications in the chemical, petrochemical, and pharmaceutical industries.
Heat Resistance: Stainless Steel 904L maintains its mechanical properties at elevated temperatures, which is crucial for flanges used in high-temperature applications. It also offers excellent weldability, making it convenient for fabrication.
Non-magnetic: 904L is non-magnetic in all conditions, making it versatile for various industries, including those where magnetic interference must be minimized.
Toughness and Durability: Flanges made from 904L exhibit exceptional toughness and durability, ensuring they can withstand the rigors of industrial use over extended periods.
Applications: Stainless Steel 904L flanges find applications across numerous industries, including:
Chemical Industry: They are used in the production and transportation of aggressive chemicals.
Petrochemical Industry: 904L flanges are vital for offshore and onshore oil and gas operations, where exposure to corrosive environments is common.
Pharmaceutical Industry: They are utilized in pharmaceutical manufacturing, where hygiene and corrosion resistance are critical.
Desalination Plants: Given their resistance to saltwater corrosion, 904L flanges are indispensable in desalination facilities.
Power Plants: They play a role in power generation, especially in high-temperature and high-pressure environments.
Marine Applications: Their resistance to saltwater corrosion makes them suitable for marine installations.
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.
