What Are Super Duplex Steel Flanges?

Super Duplex Steel Flanges have become integral parts of industrial applications due to their exceptional properties. Engineered from super duplex stainless steel containing both ferrite and austenite phases, super duplex flanges offer remarkable machinability qualities which makes them indispensable components.

Super duplex steel flanges deliver outstanding machinability performance, even given their superior strength and corrosion resistance. Conventional machining methods make machining them relatively effortless - this benefit favors manufacturers as it reduces production times and costs.

Corrosion resistance is another defining characteristic of super duplex steel flanges, showing exceptional protection from harsh chemicals, acids, and seawater environments. Their corrosion-resistance extends their lifespan and ensures reliable performance under harsh industrial settings.

Weldability of super duplex steel flanges is of critical importance in industries where welding is an everyday practice, particularly those such as oil & gas and marine where welding procedures must be executed regularly and without complications. Super duplex steel flanges feature excellent weldability which facilitates their fabrication and installation with relative ease; their exceptional weldability also allows them to remain safe against possible explosions during welding procedures while protecting material integrity while optimizing properties of super duplex alloy materials.

Super duplex steel flanges find extensive use across industries due to their outstanding properties, including oil and gas exploration and production, chemical processing, marine engineering projects, desalination plants and desalinization plants. Their strong construction makes them suitable for demanding environments due to high strength corrosion resistance durability properties.

Super duplex steel flanges find applications across a range of industries. Their uses range from offshore oil rigs for connecting pipelines, chemical processing plants for handling corrosive fluids, power generation facilities for steam systems and desalination plants for turning seawater into freshwater; to pressure vessels, heat exchangers and other critical components where reliability is of utmost importance.

Manufacturing Process Of Super Duplex Steel Flanges

Raw Material

Raw Material

At the very first process, the system controls check the quality of supplies raw materials as per the test certificate and also visual and dimension.

Material Inspection

Material Inspection

Incoming quality control (IQC) is the process of observes the quality of materials and parts for manufacturing a product before production starts.

Material Cutting

Material Cutting

In this process refers to manufacturing flanges by cutting stripes from the middle plate and then rolling them into round shape.

Flange Forging

Flange Forging

Forged flanges generally have lower carbon content than cast flanges and are less disposed to rust. In Forgings Material Grade Check, weight measuring, and control the temperature.

Final Inspection

Final Inspection

In this method measure & inspect the dimension & size of the flange. The diameter is check to control what size pipe a flanges can be used.
