Factory Tour

Inside Our Forging, Machining & Inspection Workflow

See how our flanges and pipe fittings move from certified raw material to forged blanks, CNC machining, marking and final inspection before they are packed for export.

What is a flange?

A flange joins pipes, valves, pumps and equipment through a bolted, gasketed connection that can be opened for inspection and maintenance.

Welded or threaded?

Threaded connections suit low-to-medium pressure lines; welded flanges and fittings are specified for high-pressure and cyclic service.

Material selection

Fitting material normally matches the pipe specification, so heat numbers and markings follow the same ASTM grade.

American Standard Pipe Fittings

Steel Pipe Fittings to ASME, ANSI, DIN, JIS, ISO & BSP Standards

Three fitting families cover almost every process piping requirement. Choose by connection type, pressure class and material grade — our engineers verify every enquiry against the governing standard before quotation.

Forged steel pipe flanges manufactured to ASME B16.5
Forged Flanges

Steel Flanges Built to ASME B16.5, EN 1092-1 & BS 10

Every flange we produce follows ASME dimensional standards and ASTM material specifications. We forge weld neck, slip on, blind, socket weld, threaded and lap joint flanges with raised face (RF), flat face (FF) or ring type joint (RTJ) facings, in smooth or serrated finish to match your gasket.

Threaded flanges are recommended for low-to-medium pressure lines, while weld neck and socket weld flanges are specified where pressure, temperature fluctuation or vibration is significant. On request, flanges can be internally coated or lined for aggressive media.

  • Pressure classes 150 to 2500 and PN 6 to PN 400
  • Facings: RF, FF, RTJ, tongue & groove, male & female
  • Dimensional, hardness and PMI checks before dispatch

Pipe Fittings Heat Numbers and Markings

Rajtilak Metal is one of India's longest-established ISO certified manufacturers of pipe bends, couplings, end caps, elbows, stub ends, reducers, tees, olets and gaskets. Our EIL and IBR approved forgings are installed in oil, gas, water, acid and petrochemical plants that demand verified material quality.

Each fitting carries the manufacturer's mark, material grade, size, schedule or class and the original heat number. That marking links directly to the EN 10204 3.1 certificate, giving inspectors full traceability from the steel mill to the installed spool.

Special Flanges & Dimension Data

Industrial Flanges and Dimension Charts from Mumbai, India

As an ISO certified manufacturer of seamless tees and reducers in stainless and carbon steel, we also produce special-purpose flanges and publish dimension and weight data to simplify your engineering checks.

Industrial spectacle blind and orifice flanges

Special Purpose Industrial Flanges

Engineered flanges for line isolation, flow measurement and large-bore connections.

  • Spectacle Blind Flange
  • Orifice Flange (ASME B16.36)
  • Large Diameter Flanges (ASME B16.47)
  • Reducing Flange

Advantages of Flanged Connections

Flanges are easy to assemble with moderate bolt torque, remove the need for adapters and allow pipes to be dismantled for cleaning, inspection or modification. With correct gasket selection and even bolt-load distribution, they resist loosening under shock, vibration, high pressure and temperature fluctuation — which is why they are trusted for toxic gases and flammable or explosive liquids.

Design Considerations

Flanged joints are heavier and larger than welded joints, and exotic alloys increase cost. For long runs with no maintenance access, buttweld fittings may be more economical. Our engineers can recommend the most cost-effective combination of flanges and welded fittings for your line class.
