二重 2205 およびスーパーデュプレックス 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, のように 304 そして 316 ステンレス鋼のネジ付きフランジ. Because of this, 二重 2205 およびスーパーデュプレックス 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.
スーパーデュプレックス 2507 threaded flanges improved corrosion resistance lends itself well too applications prone to stress-corrosion cracking, 隙間腐食, 穴あき, erosion and general corrosion. Because of the properties of Duplex and Super Duplex stainless steel threaded flanges are often used in chemical processing, 石油化学製品, 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 およびスーパーデュプレックス 2507. Gain more insight on these two grades by accessing our Duplex 2205 およびスーパーデュプレックス 2507 overviews or by contacting our engineering experts.

Strength Meets Sealing in Duplex & スーパー二相鋼ねじ込みフランジ
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 ステンレス鋼, while super duplex options provide improved resistance to stress-corrosion cracking, 隙間腐食, 穴あき, 浸食, and general corrosion for demanding offshore platforms and oil and gas service.

どこでデュプレックス & Super Duplex Steel Threaded Flanges Perform Under Pressure
Duplex super duplex steel threaded flanges are widely used in chemical processing, 石油化学製品, 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, スーパーデュプレックス 2507 performs especially well in warm chlorinated seawater and acidic, chloride containing media.

よくある質問
Q: What is a duplex super duplex steel threaded flanges used for?
あ: 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, 化学処理, 海水, 脱塩, 石油とガス, and sour service systems where high chloride resistance, 強さ, そして NACE MR0175/ISO 15156 compliance are required. Service temperature should generally remain below 570°F to preserve duplex microstructure performance.
Q: What materials are available for duplex super duplex steel threaded flanges?
あ: Available grades include Duplex 2205 で UNS S32205 / UNS S31803, EN/Werkstoff 1.4462, plus Super Duplex 2507 で UNS S32750, 材料 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.
Q: What pressure ratings does a duplex super duplex steel threaded flanges support?
あ: The exact pressure class is not specified in the provided data, so rating must be confirmed against flange dimensions, ねじの形状, 材質グレード, 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.
Q: What standards does a duplex super duplex steel threaded flanges comply with?
あ: These flanges can be supplied to major duplex and super duplex material standards including ASME SA/A182, ASTM A182, ASTM A240, ASTM A276, ASTM A479, ASTM A789, ASTM A790, ASTM A815, EN 10088, EN 10216-5, NACE MR0175, そして ISO 15156-3.
