We make the flanges in the standard specifications or customized specifications as needed by the customers. Some of the properties of SS 347/347 H flanges is that they show improves resistance to corrosion as well as have high creep resistance features. These flanges are best for use in the application where there is continuous heating is required in the range of the 800-1650F.

Also, this grade shows useful mechanical feature at elevated temperature. These flanges are used in the aeroplane exhaust stacks, expansions joints, annealing box, collector ring, etc. We mainly manufacture SS 347/347H flanges in the form- forges flanges, socket weld flanges, welding neck flange, long weld neck flange, reduced flange, etc.

The type of flange you get is a flat face, ring type and raised face flange. These flanges we produce are highly durable because we perform various tests to check the product quality. The test we perform on the product is mainly- hardening, tensile test, chemical analysis, PMI, IGC test, micro and macro test. The tested material is also inspected by highly knowledgeable team of professionals.
