Navgraha Steel &Engg Company are exporting and trading with various range of flanges to client industries. A brief on the product is highlighted below.
What exactly do we understand by Super duplex?
Super duplex is basically an austenitic alloy. It has ferrite and chromium metals with nickel. There are additions like molybdenum too. They protect the tool from pitting. Such alloys are known for their high tensile strength. They are a better choice than regular austenitic stainless steel.
Material used for flanges:-
• Molybdenum and chromium give the flanges combatting strength against harmful media.
• Nickel makes the flanges improve formability capacity. It also makes the product convenient for the welding process. Ductility is also increased additionally.
• The ferrite content makes the flanges harder.
• Manganese reduces the brittleness of the product and gives them more robustness.
• Steel basically has all the qualities which offer machinability and compatibility to their contained products.
These flanges can efficiently work in halide present environments too. They do not get cracked or reframed in their presence.
Purpose of flanges is as follow:-
Flanges are connectors actually used for joining pipes, tubes, vessels. They are very important in the pipework system. Ways of attaching such flanges to machines can be temporary or permanent. Some flanges are threaded and some can be directly welded. Tools like bolts and gaskets are needed for sealing the joints accurately.
Characteristics of Super Duplex UNS NO32750 Flanges:
• They can fight against various kinds of corrosion.
• They exhibit strength of high impact at zero temperatures.
• They never fall prey to crevice corrosion.
• They are far better than austenitic or duplex types of steel.
• The low temperature toughness of these flanges is greater than other flanges.
Industries of their uses have exposure to heavy work and may have extended hours of continuous work. Super Duplex UNS 32760 flanges can perfectly fit into such requirements and make them working smoothly.
Where can be such Super Duplex UNS NO32750/32760 Flanges used?
These flanges can be useful for critical applications. They can be beneficial for water desalination plants, power generation units, petrochemicals, oils and gas industry, etc.
The prices of these flanges are modestly quoted.
