Main Properties
● High strength: Duplex steel flanges have high mechanical properties such as yield strength, tensile strength and elongation, and are able to withstand large pressures and loads.
● Excellent corrosion resistance: Duplex steel flanges show good corrosion resistance in various corrosive media, especially in the corrosive environment of high temperature and high pressure, salt water environment as well as marine mining, its corrosion resistance is especially excellent.
Classification
Duplex steel flanges can be categorized into various types based on specific alloy composition and performance requirements, such as ASTM A182 F51. These different types of duplex steel flanges have their own unique application scenarios and performance advantages.
Areas of Application
Duplex steel flanges are widely used in many fields due to their excellent performance:
● Chemical Industry: Used in the production of corrosion proof pipe system, reactor, etc.
● Marine: Used in seawater desalination, offshore oil extraction, etc.
● Oil & Gas: It is used in the connection of pipeline and equipment in high-pressure, high-temperature and corrosive environment.
● Food Processing: Double Steel Flanges are also important in food processing facilities with high sanitation standards and corrosion-resistant requirements.
Preparation and Processing
The preparation and processing of duplex steel flanges include casting, forging, rolling, welding and other processes. These processes can ensure that the dimensional accuracy, surface quality and mechanical properties of the flanges meet the requirements for use. During processing, parameters such as temperature, pressure and welding current need to be strictly controlled to avoid material deformation, cracking and other problems.
