Blossom Steel supplies Hastelloy flanges in India and Mumbai for process piping, chemical equipment,
petrochemical systems and other demanding industrial installations. Our range covers Hastelloy C276,
C22, B2, B3, C4 and X flanges in different sizes, pressure classes and face configurations.
Hastelloy flanges can be supplied in sizes from 1/2″ (15 NB) to 48″ (1200 NB), with Class 150 to
Class 2500 pressure ratings and applicable PN ratings. Flanges can be sourced in forged, threaded,
screwed and plate forms with RF, FF, RTJ and other specified facing arrangements.

Blossom Steel can source Hastelloy flanges in different configurations according to the piping layout, connection method and dimensional specification.
Hastelloy flanges are available for standard piping sizes as well as larger-diameter requirements. The required NPS or DN size should be specified together with the pressure class and flange standard because dimensional details vary between standards.
The supplied size range includes 1/2″ (15 NB) to 48″ (1200 NB), with broader DN10 to DN5000 sizing indicated for applicable flange requirements.
For quotation, provide:
Hastelloy flanges can be supplied across several pressure classes for different piping and equipment configurations.
The applicable pressure rating should be selected against the flange standard, material grade, size and operating conditions rather than treating pressure classes as interchangeable between standards.
Different face configurations are available to match the mating flange, gasket arrangement and piping design.
For RF, FF and RTJ requirements, the purchase specification should identify the required facing together with the flange standard and pressure class.
Hastelloy flanges can be supplied against commonly specified international flange standards, depending on the required size, pressure class and connection design.
Applicable standards include:
The standard should be confirmed before ordering because bolt-hole patterns, dimensions, facing and pressure designations can vary between standards.
Hastelloy flanges can be sourced in forged, threaded, screwed and plate configurations according to the required connection and manufacturing specification.
Available surface treatments and finishes include:
Machining and finishing details can be matched to the applicable flange drawing or purchase specification.
Inspection documentation can be supplied according to the purchase requirement and project specification.
Available documentation includes:
Inspection requirements should be stated at the enquiry stage so the quotation can be prepared against the correct documentation level.
Hastelloy flanges are used to connect piping, valves, vessels and process equipment where the selected nickel-alloy grade is specified for demanding service conditions.
The flange grade should be matched with the piping material and service conditions specified for the installation.
Blossom Steel supplies Hastelloy flanges for industrial buyers across India in commonly specified grades, sizes, pressure classes and face configurations. Stock and procurement availability can vary according to flange size, grade and pressure rating.
For standard sizes, availability can be checked against the required quantity. Larger sizes, less common grades and project-specific configurations can be sourced against the exact purchase specification.
Check Grade, Size & ClassBlossom Steel supplies Hastelloy flanges for Mumbai-based industrial and project buyers according to the required grade, NPS/DN size, pressure class, face type and quantity.
For Mumbai enquiries, provide the flange standard and dimensional requirement along with the required delivery quantity so the available material can be matched to the order specification.
Send Mumbai Flange EnquiryMumbai buyers can source Hastelloy C276, C22 and other specified grades in different flange configurations and pressure classes. Standard sizes can be checked for availability, while special sizes and project-specific flange configurations can be sourced against the required specification.
Check Mumbai StockBlossom Steel supplies Hastelloy flanges for customers across India, supporting requirements for standard piping flanges as well as specified project orders.
For a precise quotation, share the Hastelloy grade, flange type, NPS/DN size, pressure class, face type, quantity and inspection requirement. This allows the material to be matched to the actual piping or equipment specification instead of quoting a generic flange.
Send your flange specification with the grade, size, type, pressure class, face, quantity and required certificates. If the order is based on a drawing, project standard or specific flange schedule, include those details with the enquiry.
