Ganpat Metal supplies ASTM B564 / ASME SB564 Hastelloy flanges for chemical processing, process equipment, petrochemical systems and other industrial piping requirements where the flange material and dimensional standard need to match the project specification.
The range covers C276, C22, C4, C2000, B2, B3 and X grades, with flange sizes from 1/2" NB to 60" NB, ASME pressure classes up to 2500#, PN ratings and FF, RF and RTJ facing configurations.
Orders can be worked from a material specification, purchase schedule or drawing, including requirements for dimensional standards, inspection, material certification and export documentation.

Hastelloy flange dimensions are governed by the applicable flange standard, while the selected pressure class determines the corresponding dimensional and drilling requirements. Ganpat Metal works with ASME/ANSI, BS, EN and DIN specifications for different procurement requirements.
| Standard | Flange Types / Scope | Pressure Range |
|---|---|---|
| ASME/ANSI B16.5 | Welding Neck, Slip-On, Blind, Socket Weld, Lap Joint, Threaded, RTJ | 150#–2500# |
| ASME/ANSI B16.47 | Welding Neck and Blind, Series A & B | 75–900 |
| ASME/ANSI B16.36 | Welding Neck, Slip-On and Threaded | 300–2500# |
| BS4504 Sec. 3.1 | Welding Neck, Hubbed Slip-On, Hubbed Threaded, Plate, Blank | PN2.5–PN40 |
| BS4504 Part 1 | Welding Neck, Hubbed Slip-On, Plate, Blank | PN2.5–PN400 |
| BS1560 | Welding Neck, Socket Welding, Slip-On, Blind, Screwed Boss, Lapped | 150–2500 |
| BS10 | Welding Neck, Plate Slip-On, Screwed Boss, Slip-On Boss, Blind | Tables D, E, F, H |
| DIN | Multiple DIN flange standards | PN6–PN100 |
For a project specifying C276, the material designation, flange type and governing standard should be considered together. The same applies when ordering C22 flanges or other Hastelloy grades where the material and dimensional requirements are defined separately.
| Parameter | Details |

The flange face is selected according to the mating connection and sealing arrangement specified for the piping system.
| Face Type | Description |
|---|---|
| Flat Face (FF) | Flat mating surface |
| Raised Face (RF) | Raised sealing surface used with the specified gasket arrangement |
| Ring Type Joint (RTJ) | Grooved face for ring-type gasket connections |
Surface finish requirements can be specified with the flange standard and face configuration where required by the purchase specification.
Select Flange options below and click the "Calculate Weight" button to reveal estimated weight. The result is an estimated weight, since actual weight can vary with the selected flange standard, dimensions, type and manufacturing specification.
The flange configuration is selected according to the piping connection, equipment arrangement and applicable dimensional standard.
For procurement, the flange type should be stated with the grade, nominal size and pressure class so the required configuration is clear.
Ganpat Metal supplies Hastelloy flanges against defined material and dimensional specifications rather than treating every flange as an identical standard item.
The manufacturing requirement can be established from:
For a C276 order, for instance, the purchase specification can identify UNS N10276 together with the flange dimensions and applicable standard. This gives the manufacturing and inspection requirements a clear material reference.
Inspection requirements can be incorporated into the order according to the project or purchase specification.
For export or project procurement, documentation requirements should be stated at the enquiry stage so they can be considered along with the material and dimensional specification.
Ganpat Metal supplies Hastelloy flanges for industrial requirements involving:
The Hastelloy grade should be selected according to the material specification established for the service rather than using one grade across unrelated process conditions.
Ganpat Metal supplies Hastelloy flanges for Indian industrial procurement as well as international orders. The supply scope covers different Hastelloy grades, flange configurations, pressure classes and dimensional standards.
The quotation can be built around the actual purchase specification, including grade, size, flange type, pressure class, face, dimensional standard, quantity and inspection documentation.
A buyer specifying Hastelloy C276 flanges can provide the UNS designation along with the required flange dimensions and class. Similarly, a C22, B2 or other grade requirement can be quoted against its specified material designation rather than being treated as a generic nickel-alloy enquiry.
Ganpat Metal supplies industrial metal products to customers across North America, Europe, the Middle East, Asia and other international markets.
Export destinations include:
India
Brazil
New Zealand
Australia
Bangladesh
Malaysia
UAE
Saudi Arabia
Oman
Egypt

Kazakhstan
For an export enquiry, the delivery country can be submitted together with the grade, flange standard, dimensions, pressure class, quantity, inspection requirements and documentation. This gives the commercial team the information needed to evaluate the order as an export specification rather than simply a domestic product enquiry.
Ganpat Metal's Hastelloy flange supply is structured around the complete product specification.
For a quotation, send the information already available from your purchase order, drawing or material schedule:
If the specification is incomplete, even the available details such as grade, size and class can be shared first. The remaining flange configuration and documentation requirements can then be established against the order.
For buyers comparing individual grades, the Hastelloy Flanges range can be used as the starting point before moving to the specific C276, C22, B2, C4, C2000, B3 or X requirement.
