Duplex Flanges

What is duplex flanges?

A flange that exhibits excellent resistance to stress corrosion cracking, when brought into comparison with 304 and 316 stainless, is duplex flange.

This austenitic-ferric stainless variant duplex steel flanges exhibits good chemical and mechanical properties, followed by minimal cost due to increased availability.

Know more about duplex steel flanges wall thickness and the advantage of DSS Spectacle Blinds as per ASME b16.5

What is the duplex steel flange’s wall thickness and the advantage as per ASME b16.5?

When comparing other grades like 316 or 304, though they are available in large amounts in stainless steel market, but there are some properties which they do not exhibit. Below are some of the benefits which are offered by DSS spectacle blinds:

• Duplex Steel threaded Flanges exhibit improved two times stronger strength than ferric and austenitic stainless steel grades.
• Under pressure, this spectacle blind exhibits good formidability and shows good toughness.
• Excellent corrosion resistance, along with resistance to crevice and chloride pitting corrosion cracking is offered by duplex steel long weld neck flanges

With the added advantages, they also come in nominal wall thickness size range of 12’’, with their standard wall thickness through 10’’.

What is the difference between a DSS lap joint and slip on flange?

There is a huge difference between DSS lap joint and slip on flange. Although both are considered the same, duplex lap joint flanges are an ideal use case where we need regular inspection and disassembly. It also is pocket friendly, thanks to its two piece design.

In scenarios where pipe is busy with toxic material, it is an ideal alternative for cost efficiency than a DSS slip on flange.

What are the testing parameters for Duplex Steel Reducing Flanges and DSS weld neck flanges?

Though it offers characteristic properties, there are some tests that are performed on DSS weld neck flange and reducing flange and below are some of the tests:

• Mill Test reports
• Stamping, colour coding check and marking.
• Pre-shipment inspection.
• Heat treatment execution test performed on duplex steel reducing flanges.
• Visual and dimensional control.
• Thickness control.
• During packaging, final visual inspection to ensure quality control.
• Documentation reviewing prior release.

What makes DSS Plate flanges and Duplex socket weld flange to be a mostly used flange in chemical processing, oil and gas industry?

Industries such as chemical processing and oil and gas, make use of duplex socket weld flange for smaller sized-high pressure pipes. These pipes ensure smooth flow. Other than this, below are some more reasons why they both plate flanges and weld flanges are common for ideal use case:

• More robust when comparing other hydraulic fittings.
• They resist losing up and are stiff.
• Provide simplicity and easy maintenance.
• DSS plate flanges can be fit in tight spaces.
