Duplex Steel Flanges deliver exceptional mechanical properties, including a minimum tensile strength of 620 MPa and maximum hardness of 290 HB. Their duplex stainless steel composition ensures outstanding impact strength, even at sub-zero temperatures, and excellent resistance against pitting and crevice corrosion. These attributes enable their reliable use in aggressive environments, such as petrochemical plants and offshore platforms.
Versatile Standards and Pressure RatingsManufactured to meet global standardsANSI, DIN, EN, ISO, JIS, GBDuplex Steel Flanges are available in a wide variety of pressure classes (Class 150 to 2500, PN 6 to PN 400). End facing options like Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) provide compatibility with diverse pipework requirements across industries, while dimensional flexibility supports tailored installations.
Precision Manufacturing and Stringent TestingProduced through advanced forging and CNC machining processes, each Duplex Steel Flange is subjected to exhaustive radiographic and ultrasonic testing. This meticulous approach ensures structural integrity, consistent surface finish (shot blasted/machined), and full traceability with grade, size, pressure, and heat number markings. This quality assurance is crucial for safety-critical applications in high-pressure systems.
FAQs of Duplex Steel Flanges:
Q: How are Duplex Steel Flanges tested for quality and reliability?
A: Duplex Steel Flanges are rigorously tested using 100% radiographic and ultrasonic inspection methods to ensure there are no internal defects. Additionally, each piece is marked with its grade, size, pressure class, and heat number for full traceability and quality assurance.
Q: What connection types are available for Duplex Steel Flanges?
A: These flanges are available in multiple connection types including weld neck, slip on, blind, threaded, socket weld, and lap joint, which allows them to be used in a wide variety of piping systems and applications.
