Plate Flanges – Manufacturer, Exporter, Supplier & Stockist in India
Vandan Alloys manufactures, supplies and exports Plate Flanges for industrial piping, fabrication, process equipment, tanks, vessels and general engineering applications. Plate Flanges are available in carbon steel, stainless steel, alloy steel and other specified materials according to customer requirements.
Plate Flanges are manufactured from plate material and machined to the required outside diameter, thickness, bore, bolt-hole arrangement and facing. They are commonly selected for applications where a practical and economical flanged connection is required.
What is a Plate Flange?
A Plate Flange is a flat flange manufactured from steel plate or specified plate material. It generally consists of a circular plate with a central bore and drilled bolt holes for connecting pipes, valves, equipment or other flanged components.
Depending on the application, Plate Flanges may be supplied with Raised Face (RF), Flat Face (FF) or other specified facing arrangements.
Plate Flanges are widely used in fabrication, low-pressure piping, tanks, water systems, structural piping and industrial equipment.
Plate Flange Types
Vandan Alloys can supply Plate Flanges in different configurations according to the required application and specification.
Flat Plate Flanges – simple plate-style flanges used for general piping and fabrication applications.
Raised Face Plate Flanges – supplied with a raised gasket seating surface where specified.
Flat Face Plate Flanges – suitable for mating arrangements requiring a flat flange face.
Custom Plate Flanges – manufactured according to customer drawings and project dimensions.
The exact configuration depends on the required standard, pressure rating, dimensions and application.

Plate Flange Materials & Grades
Vandan Alloys supplies Plate Flanges in a range of materials for different industrial environments.
Carbon Steel Plate Flanges
Common carbon steel grades include:
ASTM A36 | ASTM A516 | Carbon Steel Plate Grades as specified
Material selection depends on application, thickness, pressure, temperature and project requirements.
A105 / A105N Flange Requirements
Where a forged flange material is specifically required, ASTM A105 or A105N should be considered instead of treating a plate flange as an equivalent forged flange.
A105N is normalized carbon steel forging material and is generally specified for forged flange applications.
For plate-manufactured flanges, the actual plate material and applicable specification should always be confirmed.
Stainless Steel Plate Flanges
Stainless steel Plate Flanges can be supplied in grades such as:
304 | 304L | 316 | 316L | 321 | 347 | 310 | 310S | 904L
Other grades can be considered according to the project requirement.
Duplex Stainless Steel Plate Flanges
Vandan Alloys can supply selected duplex plate flange requirements in:
UNS S31803 / S32205 – Duplex 2205
Super Duplex Stainless Steel Plate Flanges
For applications requiring higher corrosion resistance and strength, selected requirements can be supplied in:
UNS S32750 / S32760 – Super Duplex 2507
Nickel Alloy Plate Flanges
Special plate flange requirements may also be considered in nickel alloys such as:
Monel | Inconel | Incoloy | Hastelloy
Availability depends on grade, dimensions, quantity and manufacturing feasibility.
Plate Flange Manufacturing Process
The manufacturing process depends on the material, dimensions and specification.
A typical process may include:
Material Selection → Plate Cutting → Profile Preparation → Machining → Bore Machining → Facing → Bolt-Hole Drilling → Deburring → Marking → Inspection → Packing
For custom Plate Flanges, production is carried out according to the approved drawing or technical specification.
Plate Flanges Size & Dimensions
Plate Flange dimensions may include:
Outside diameter
Flange thickness
Bore diameter
Bolt-hole diameter
Number of bolt holes
Bolt-hole circle / PCD
Face dimensions
Overall dimensions
Special cut-outs or machining
For standard replacement requirements, customers should provide the nominal pipe size, pressure requirement, material and applicable standard.
For non-standard requirements, a drawing is strongly recommended.
Plate Flange Facing
Plate Flanges can be supplied with the required facing according to the application.
Flat Face – FF
A Flat Face flange has a flat gasket seating surface and is commonly used in selected lower-pressure or equipment connections where specified.
Raised Face – RF
A Raised Face flange provides a raised gasket seating area and is widely used in industrial piping systems where specified.
The mating flange and gasket must be compatible with the selected facing.
Plate Flanges Pressure Requirements
Plate Flanges are often used in applications where the pressure requirement and flange design are suitable for a plate-style construction.
The required thickness, drilling, material and facing should be determined according to the applicable design and project specification.
A Plate Flange should not automatically be considered interchangeable with a forged flange simply because the nominal dimensions appear similar.
Plate Flanges vs Forged Flanges
The manufacturing route is the main difference.
Plate Flange: manufactured from plate material through cutting and machining.
Forged Flange: produced from forging stock through a controlled forging process followed by machining and other required operations.
The appropriate construction depends on pressure, temperature, material specification, code requirements, application and customer engineering requirements.
For critical pressure applications, the specified flange standard and material specification should be followed rather than selecting only on price or appearance.

Plate Flanges are used in various piping and fabrication environments, including:
Water Piping
