Since they are constantly in contact with liquids and gases, the alloy steel orifice flanges possess corrosion-resistant properties to protect them against rusting when functioning. This resistance is broadened to cover its heat resistant characteristics, which aides it to operate efficiently even at higher temperatures and pressure, without cracking down. The aforementioned properties are common to all the types of orifice flanges available, however, different grades of flanges might exhibit different intensities of the general properties.
These flanges are employed in almost all the industries which make use of strong piping systems, a few of those are; Gas Processing, Petrochemical, Steam Power Plants, Food Industries, Chemical Manufacturing Plants, Pharmaceutical. Heavy-machinery Engineering, Mining, etc.
Since orifice flanges serve as an important component of the pipes, not only economically but also in terms of safety, it becomes even more important to ensure their quality. Therefore, our skilled professionals test every orifice flange forged in our factories before dispatching it.
