Дуплекс 2205 и Супер Дуплекс 2507 stainless steel slip on 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 stainless steel slip on flanges. Because of this, Дуплекс 2205 и Супер Дуплекс 2507 steel are some of the most common grades of duplex used for slip on flanges with Super Duplex 2507 slip on flanges being the more corrosion resistant grade of the two.
Супер Дуплекс 2507 slip on 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 slip on 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.

Дуплекс 2205 includes UNS S31803, UNS S32205, Вт.
NR./EN 1.4462, и материал 1.4462, with a mixed microstructure of roughly equal ferrite and austenite.
Супер Дуплекс 2507 является UNS S32750, материал 1.4410, while Zeron 100/F55 is UNS S32760, Вт.
Nr./EN 1.4501.
Use should be limited below 570° F because extended elevated temperature exposure can embrittle the material.
Where Duplex Super Duplex Steel Slip on Flanges Perform Under Pressure
Duplex super duplex steel slip on flanges from SASA FLANGE are widely used in chemical processing, нефтехимия, the power industry, and seawater equipment because they combine strength with corrosion resistance.
For offshore oil platforms, they suit piping exposed to aggressive marine conditions.
In subsea oil and gas pipelines, Супер Дуплекс 2507 helps resist chloride attack and stress-corrosion cracking.
In desalination equipment and warm chlorinated seawater service, Супер Дуплекс 2507 and Zeron 100/F55 are especially well suited.
Act Fast on Duplex Super Duplex Steel Slip on Flanges from SASA FLANGE
SASA FLANGE delivers duplex super duplex steel slip on flanges with practical installation benefits, including easier pipe alignment because the flange can slide through the hub and spin freely.
They are typically lower in price than weld-neck flanges, though they require two fillet welds.
We support custom manufacturing with 10-20 days lead time, при поддержке ISO 9001:2015, ferrite content testing, испытание на удар, and PMI verification.

Часто задаваемые вопросы
вопрос: What is a duplex super duplex steel slip on flanges used for?
А: These slip on flanges connect piping, клапаны, насосы, and equipment in corrosive, chloride-bearing, and high-pressure systems. Дуплекс 2205 and Super Duplex 2507/F55 are widely used in offshore oil and gas, seawater handling, опреснение, химическая обработка, and sour service lines requiring NACE MR0175/ISO 15156 согласие. Their duplex microstructure provides high strength, good weldability, and strong resistance to pitting, щелевая коррозия, and stress corrosion cracking below 570°F.
вопрос: What materials are available for duplex super duplex steel slip on flanges?
А: Available grades include Duplex 2205 в UNS S32205 and related UNS S31803 / EN 1.4462, plus Super Duplex 2507 в UNS S32750 / EN 1.4410 and Zeron 100 / F55 in UNS S32760 / EN 1.4501. These two-phase stainless steels contain roughly balanced ferrite and austenite, delivering higher strength and improved chloride corrosion resistance than standard austenitic stainless steels. Material test certificates are supplied to EN 10204 3.1.
вопрос: What pressure ratings does a duplex super duplex steel slip on flanges support?
А: Pressure rating depends on flange dimension standard, размер, толщина стенки, and grade, not only the alloy. These slip on flanges are commonly produced to ASME pressure classes such as 150, 300, 600, 900, 1500, и 2500, subject to project specification. Duplex and Super Duplex offer higher mechanical strength than austenitic stainless steels, but service temperature should remain below 570°F to avoid embrittlement during prolonged exposure.
вопрос: What standards does a duplex super duplex steel slip on flanges comply with?
А: These flanges are manufactured from materials covered by ASME SA/ASTM A182, A240, A276, A479, A789, A790, A815, and related EN 10088 и RU 10216-5 требования. Available grades include UNS S32205, S32750, and S32760, aligned with NACE MR0175 / ISO 15156 for sour service and NORSOK MDS D45 Grade F51 or MDS 055 where specified.
