Manufacturer, Stockholder, Suppliers and Exporter of Pipe Weld Neck Flange in India
Devdeep Steel Alloys (India) is a dynamic group, which was established over a decade ago to cater to growing demands of Weld Neck Flange standards in ASME B16.5 Flange/ ANSI B16.5 Flange|ASME B16.47 Flange/ANSI B16.47 Flange etc in all materials like Stainless Steel , Carbon Steel & High Nickel Alloys.
Weld Neck Flange is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flange prior to welding both inside and outside. High quality Weld Neck Flange are ideal for lower pressure applications.
We Manufacture, Export and Supply Weld Neck Flange which meets with national and international quality standards and producing base which owns equipments conforming to international technical level and is well equipped with a whole set of advanced plasma refining equipments. We export our high quality Weld Neck flanges to Kuwait, Egypt and Qatar.
