Gautam tubes engaged in producing, supplying and exporting a superior range of DUPLEX STEEL FLANGES. These flanges are extensively used in the piping system and strengthen piping applications. We supply industrial flanges in various tolerance limits and machining limits for multiple applications. Flanges are offered in various grades like Duplex Steel S31803 Flanges, standards, thickness, specifications and custom dimensions.
We manufacture and supply flanges in accordance with national and international standards. Here we also follow industrial design codes to process flanges in utmost quality. We use top notch quality of duplex steel to process flanges with higher dimensional accuracy and surface finish. These duplex flanges are the optimum option for impact assemblies.
DUPLEX STEEL FLANGES are ferritic and austenitic grade flanges. These flanges have good corrosion resistance and high strength features. These flanges have good local and general corrosion resistance ability than single ferritic or austenitic flanges. Mainly, these flanges are used in industrial sectors such as chemical processing, seawater applications, thermal processing industries and so on.
DESCRIPTION
Duplex steel flanges are better than any other type of standard grade flanges. In severe acidic environments, these flanges offer good resistance even where acid concentration is higher. The high-temperature strength of flanges are higher and similar to standard types of grades in the temperature range between 950 deg C to 1150 deg C. these flanges show a rapid enhancement in the strength in lower temperatures up to 900 deg C. for effective cold working operations, precautions is taken for stress relieving and deformation is considerably low in this grade.
CONCLUSION
The solution annealing treatment is done between temperature 1040 deg C and above exposure is not recommended. After heat treatment, it is followed quenching with water or air. DUPLEX STEEL FLANGES serve good performance in reducing environments, especially when exposed to chemical environments that contain acetic acids, formic acids, sulfuric acids, nitric acids and more. Functionality in moist environments is also greater. Duplex flanges have great workability when applied in concentrated organic and inorganic compounds.
These flanges offer non-permanent joints and can be bolted. Especially, these are applied where regular maintenance is required. Flanges strengthen any assembly where impact forces are encountered.
