Дуплекс 2205 и Супер Дуплекс 2507 stainless steel threaded flanges are characterized by their high yield strength, which is twice that of the annealed yield strength of typical austenitic stainless steels, нравиться 304 и 316 фланцы из нержавеющей стали с резьбой. Because of this, Дуплекс 2205 и Супер Дуплекс 2507 steel are some of the most common grades of duplex used for threaded flanges with Super Duplex 2507 threaded flanges being the more corrosion resistant grade of the two.
Супер Дуплекс 2507 threaded flanges improved corrosion resistance lends itself well too applications prone to stress-corrosion cracking, щелевая коррозия, питтинг, erosion and general corrosion. Because of the properties of Duplex and Super Duplex stainless steel threaded flanges are often used in chemical processing, нефтехимия, power industry and seawater equipment.
Usage of both Duplex and Super Duplex stainless steel should be limited to temperatures below 570° F as extended elevated temperature exposure can embrittle this material.
The most common grades of Duplex flanges are Duplex 2205 и Супер Дуплекс 2507. Gain more insight on these two grades by accessing our Duplex 2205 и Супер Дуплекс 2507 overviews or by contacting our engineering experts.

Strength Meets Sealing in Duplex & Супердуплексные стальные фланцы с резьбой
SASA FLANGE supplies duplex super duplex steel threaded flanges engineered for high yield strength and dependable corrosion resistance.
These threaded flanges use a tapered female thread to join male pipe threads and create a tight seal without welding.
Duplex grades offer about 2x stronger yield than 316 нержавеющая сталь, while super duplex options provide improved resistance to stress-corrosion cracking, щелевая коррозия, питтинг, erosion, and general corrosion for demanding offshore platforms and oil and gas service.

Где Дуплекс & Super Duplex Steel Threaded Flanges Perform Under Pressure
Duplex super duplex steel threaded flanges are widely used in chemical processing, нефтехимия, power industry, and seawater equipment because they combine strength with corrosion resistance.
For offshore oil platforms, they suit hazardous areas where welding is too dangerous.
In subsea oil and gas pipelines, threaded sealing supports connections when post weld heat treatment is not possible.
In desalination and seawater systems, Супер Дуплекс 2507 performs especially well in warm chlorinated seawater and acidic, chloride containing media.

Часто задаваемые вопросы
вопрос: What is a duplex super duplex steel threaded flanges used for?
А: These threaded flanges connect threaded pipe or fittings without welding, using a tapered female thread for secure assembly and easier maintenance. They are used in offshore, химическая обработка, морская вода, опреснение, нефть и газ, and sour service systems where high chloride resistance, сила, и NACE MR0175/ISO 15156 compliance are required. Service temperature should generally remain below 570°F to preserve duplex microstructure performance.
вопрос: What materials are available for duplex super duplex steel threaded flanges?
А: Available grades include Duplex 2205 в UNS S32205 / UNS S31803, EN/Werkstoff 1.4462, plus Super Duplex 2507 в UNS S32750, материал 1.4410, and Zeron 100 / F55 in UNS S32760, EN 1.4501. These alloys have a mixed ferrite-austenite microstructure, typically near 50/50, providing higher yield strength than standard austenitic stainless steels with improved pitting, crevice, and stress corrosion resistance.
вопрос: What pressure ratings does a duplex super duplex steel threaded flanges support?
А: The exact pressure class is not specified in the provided data, so rating must be confirmed against flange dimensions, форма резьбы, сорт материала, and applicable ASME design code. Threaded flanges are typically selected for moderate-pressure systems where welding is avoided. For duplex and super duplex service, rating verification should also consider temperature limits below 570°F and the required corrosion allowance for the process medium.
