The major characteristic of the alloy steel weld neck flange is its ability to withstand and function efficiently in an oxidizing environment. This potential of the flanges is because of its anti-corrosion property which makes them resistant to acids and liquid corrosive agents. These weld neck flanges also possess a heat-resistant property which allows them to be welded and operated at a higher temperature, without causing any major changes in their structure and physical properties. The alloy can be operated in cold conditions effectively, making it efficient to be utilized at temperatures lower than room temperature. The flanges are very ductile and can be efficiently welded according to the desired structure and thickness.
Among the wide range of applications showcased by the alloy steel weld neck flanges, some of them are Heat Exchange vessels, Power Generating Plants, Oil Processing, Condensers, Refineries, Petrochemical, Chemical Industries, etc.
Before we dispatch our alloy steel weld neck flanges, several tests are conducted on the flanges such as Mechanical Test, Hardening Test, Micro and macro Test, Chemical Test, etc.
