Operating in an oxidizing atmosphere is a challenge because of corrosion, but alloy steel threaded/screwed flanges can withstand the oxidation and function satisfactorily in such conditions. These alloy threaded steel flanges are also capable of working at higher temperatures without any effect on their robustness and any degradation. They have head hardening properties which makes the alloy screwed flanges tougher and vigorous in elevated temperatures. The impressive ductility displayed by the alloy steel flanges makes them efficient in high-pressure conditions. Acid corrosion-resistant is another characteristic of the alloy flange in consideration.
The ever-so versatile alloy steel threaded flanges are utilized in several industries, a few being; Pulp and Paper Industry, Oil Refining, Petrochemical, Energy Production Plants, Breweries, Refineries, Heat Exchangers, Pharmaceuticals, Chemical Equipment, etc.
Our flanges are constantly subjected to tests through various stages, even during handling and these tests are followed by certification as well as Third-Party Inspections from the authorities.
