Hastelloy C276 has a supplied density of 8.89 g/cm³, which can be used as the material density for estimating flange weight.
Actual flange weight depends on the selected flange type, nominal size, pressure class, bore, hub dimensions, face configuration and applicable dimensional standard.
For a more accurate estimated weight, provide the flange type, size, pressure class and dimensional standard.
Ganpat Metal supplies Hastelloy C276 flanges according to the required connection arrangement, piping standard and project drawing.
Ganpat Metal manufactures Hastelloy C276 flanges through forging, heat treatment and machining according to the required material specification and dimensional configuration.
The manufacturing requirement is established from the purchase specification, applicable flange standard and project drawing where provided.
Key manufacturing requirements can include:
For non-standard configurations, the enquiry should include the required drawing or dimensional schedule along with the material grade and applicable standard.
Testing and inspection are established according to the purchase order, material specification and project requirements.
Inspection and testing can include:
Documentation can include EN 10204 3.1B, raw material certificates, chemical analysis reports, mechanical test results, dimensional inspection records and applicable NDT reports.
The required inspection level should be defined at the enquiry stage so the quotation and documentation package can be aligned with the project requirement.
Hastelloy C276 flanges are supplied for industrial piping and equipment requirements where the specified material grade and flange configuration are required.
Typical applications include:
The final Hastelloy C276 flange configuration should be selected according to the process conditions, piping design, applicable standards and engineering specification.
Ganpat Metal Pvt. Ltd. handles Hastelloy C276 flange requirements based on the complete procurement specification, including material grade, size, pressure rating, flange type, face configuration, dimensional standard and inspection requirements.
