Industrial Flanges for Oil & Gas – Manufacturer, Exporter, Supplier & Stockist in India
Vandan Alloys manufactures, supplies, stocks and exports Industrial Flanges for Oil & Gas applications, supporting piping, process lines, equipment connections and project requirements across the energy sector.
Our flange range includes Weld Neck, Blind, Slip-On, Socket Weld, Threaded, Lap Joint, Orifice, Long Weld Neck and RTJ Flanges in carbon steel, stainless steel, alloy steel, duplex, super duplex and nickel alloy materials.
Based in Mumbai, India, Vandan Alloys supplies flange requirements for oil & gas companies, refineries, petrochemical plants, EPC contractors, maintenance projects and industrial piping systems.
Flanges for Oil & Gas Piping Systems
Oil & gas facilities use flanged connections across many sections of a piping system, including process lines, equipment connections, valves, pumps and maintenance points.
The correct flange selection depends on factors such as:
Pipe size
Pressure class
Temperature
Material
Process medium
Flange type
Facing
Piping standard
Project specification
Vandan Alloys supplies flanges according to the applicable standard and customer requirements rather than using one configuration for every application.
Flange Types for Oil & Gas Applications
Our industrial flange range includes:
Weld Neck Flanges
Blind Flanges
Slip-On Flanges
Socket Weld Flanges
Threaded Flanges
Lap Joint Flanges
Orifice Flanges
Long Weld Neck Flanges
RTJ Flanges
Forged Flanges
Special Flanges
Custom Drawing Flanges
RF, FF and RTJ configurations can be supplied where applicable.
Carbon Steel Flanges for Oil & Gas
Carbon steel flanges such as ASTM A105 and A105N are widely used in suitable oil & gas piping applications.
They can be supplied in different flange types, sizes and pressure classes according to the applicable piping specification.
For critical service, the material grade and required heat treatment, testing and documentation should be confirmed from the project specification.
Stainless Steel Flanges for Oil & Gas
Vandan Alloys supplies stainless steel flange grades including:
304 / 304L, 316 / 316L, 321, 347, 310 / 310S and 904L
Stainless steel selection depends on corrosion conditions, process fluid, temperature and other service requirements.
Duplex & Super Duplex Flanges
For applications requiring specific combinations of corrosion resistance and mechanical performance, Vandan Alloys supplies:
Duplex 2205 – UNS S31803 / S32205
Super Duplex 2507 – UNS S32750 / S32760
These grades can be supplied in suitable flange configurations according to the project specification.
Nickel Alloy Flanges
For demanding process environments, we can supply flanges in nickel-based materials including:
Nickel 200 / 201
Monel 400 / K-500
Inconel 600 / 601 / 625 / 718
Incoloy 800 / 800H / 800HT / 825
Hastelloy C276 / C22
Special material requirements are reviewed according to the operating conditions and applicable material specification.
High Pressure Oil & Gas Flanges
Vandan Alloys supplies high-pressure flange requirements in applicable classes such as:
Class 600, Class 900, Class 1500 and Class 2500
Other classes can be considered where covered by the applicable standard.
For high-pressure applications, selection must consider the complete combination of material, size, pressure class, temperature, facing, gasket and bolting requirements.
RTJ Flanges for Oil & Gas
Ring Type Joint (RTJ) Flanges are used where an RTJ connection is specified for the piping system.
Vandan Alloys supplies RTJ flange configurations in suitable materials and pressure classes.
RTJ groove dimensions and ring compatibility must correspond to the applicable standard and mating components.
Orifice Flanges for Flow Measurement
Oil & gas facilities frequently require controlled flow measurement within process and utility piping.
Vandan Alloys supplies Orifice Flanges designed for use with suitable orifice plate and differential-pressure measurement arrangements.
Pressure tapping details and flange dimensions can be supplied according to the applicable flow-measurement specification or customer drawing.
Large Diameter Oil & Gas Flanges
Large-diameter flange requirements can involve pipeline systems, equipment nozzles and other major process connections.
Vandan Alloys can review large diameter and special flange requirements according to the required standard, material, dimensions and project specification.
For large-diameter requirements, the exact dimensional standard and flange configuration should be confirmed before manufacturing.
Standards
Industrial flanges for oil & gas applications can be supplied according to applicable standards such as:
ASME B16.5
ASME B16.47
ASME B16.36 for applicable Orifice Flanges
EN 1092-1
DIN
JIS
BS
Customer / Project Specification
The applicable standard depends on the flange type, size and project requirement.
