By above manufacturing and treatment process higher resistance to crevice corrosion, pitting corrosion and IGC corrosion is achieved. These flanges are resistive many organic and inorganic compounds such as nitric, phosphoric, sulfuric and hydrochloric acid and so on. These flanges are immune to chloride-induced stress corrosion. These flanges perform well in the environments that contain severe damaging compounds. However, it has elevate mechanical strength is achieved by the heat treatment process.
These flanges have excellent creep strength. All standard type of manufacturing process is used such as cold and hot working process. The hot working operations are used to achieve higher strength, fracture toughness by performing a cold working operation that avoids brittleness.
The manufactured range of flanges is gone through with relevant qualification tests in order to get the flawless quality of products. The tests are a destructive/non-destructive test, PMI test, radiographic test, thermal performance test, hardness test, pitting corrosion test, ultrasonic test, and mechanical test. Other tests are a chemical test, intergranular corrosion test, visual inspection, etc.
