Why Are Flanges Used in Piping Systems, Storage Tanks, Industrial Fittings & Pipe Spools?

Flanges are essential mechanical components used to connect pipes, valves, pumps, instruments, storage tanks, pressure vessels, and fabricated pipe spools using bolted and gasketed joints. They provide leak-proof performance, high mechanical strength, and easy access for inspection and maintenance. Flanges are widely preferred in industrial piping because they can be dismantled and reassembled without cutting or welding pipes.

Major Reasons Why Flanges Are Used

• Easy assembly and disassembly for shutdowns, repairs, and modifications
• Leak-proof sealing using suitable gasket types
• Strong mechanical joint to handle internal pressure, vibrations, and temperature
• Ensures accurate alignment between connected components
• Supports modular construction and future piping expansion
• Interchangeable design as per ASME, DIN, EN, and JIS standards
• Available in various materials suitable for high-temperature and corrosive services

Flanges eliminate the need for fully welded joints where frequent maintenance is required.

Application Areas of Flanges

1. Piping Systems
   Flanges are used as connecting points in process pipelines for oil, gas, steam, water, and chemicals. They ensure operational safety and help in quick access for cleaning, hydro testing, and inspection during plant shutdowns.
    
2. Storage Tanks & Pressure Vessels
   Flanges are used for tank nozzles, manways, vents, drains, and instrumentation connections. They provide secure sealing and easy operational access in pressurized and hazardous service environments.
    
3. Flanged Pipe Fittings
   Flanges are used to assemble elbows, tees, reducers, valves, strainers, flow meters, and specialty fittings. This allows faster replacement of components and improves system reliability in critical service lines.
    
4. Pipe Spools & Modular Skid Assemblies
   Flanges enable fast installation of pre-fabricated pipe spools at project sites. This reduces manpower needs, improves project delivery time, and ensures high-quality fabrication done under controlled workshop conditions.

Industries Where Flanges Are Widely Used

• Oil & Gas Refinery and Petrochemicals
• Chemical Industries and Pharmaceuticals
• Power Plants and Desalination Units
• Fertilizers, Steel Plants and Mining
• Marine, Shipbuilding and Offshore Platforms
• Food Processing and Water Treatment Plants

Flanges are crucial for maintaining operational safety and integrity in industrial facilities.

Common Flange Materials

• Stainless Steel: 304/304L, 316/316L, 321, 347, 904L
• Carbon Steel: ASTM A105, A350 LF2, A516 Gr.70
• Alloy Steel, Duplex and Super Duplex Steel
• Inconel, Monel, Hastelloy and Nickel Alloy Flanges
• Galvanized and Non-Ferrous Metals for special services

Material selection depends on corrosion, pressure rating, and working temperature of the application.

Certifications & Standards

• ASME B16.5: ½” to 24”
• ASME B16.47 Series A & B: 26” to 60”
• Pressure Rating: 150#, 300#, 600#, 900#, 1500#, 2500#
• NACE MR0175 / MR0103, IBR, PED compliance available

All flanges can be supplied with MTC EN 10204 3.1 / 3.2 as required.

Why Flanges Instead of Welding?

• Quick dismantling for inspection and cleaning
• Easier replacement of equipment and fittings
• Better alignment during construction and modifications
• Saves shutdown time and reduces installation cost

Flanges help extend the life of the piping system by reducing operational challenges during maintenance.

Types of Flange Facing & Their Purpose

Different flange facings help achieve specific types of sealing performance:

• RF (Raised Face): Most common; gasket sits on a raised surface
• FF (Flat Face): Used with cast iron or fiberglass flanges to prevent bending
• RTJ (Ring Type Joint): For extreme pressure, temperature, and gas-tight sealing
• Male & Female (M/F): Controlled gasket compression
• Tongue & Groove (T/G): Ideal for repetitive opening, ensures accurate alignment

Surface Finish & Roughness Requirements

• Proper gasket seating depends on machined serrated finish (125–500 AARH) 
• Too smooth = leakage
• Too rough = damages gasket

Ensuring correct groove pattern avoids failure in high-pressure services.

Selection of Gasket Materials

Gasket choice affects sealing performance:

• Spiral Wound Gaskets — common in refinery service
• RTJ Metal Gaskets — high-pressure / high-temperature
• Compressed Fibre / Rubber — low-pressure and water lines
• PTFE & Graphite — chemical & thermal resistance

Right gasket = Extended service life + Zero leakage

Bolt Tightening & Torque Requirements

• Uniform tightening prevents leakage, bending & stress concentration
• Torque values depend on:
  • Bolt grade (B7, B8, B16 etc.)
  • Pressure class
  • Gasket material
  • Lubrication factor

Incorrect bolting is a major cause of flange joint failure.
 

Pressure Classes & Their Strength Behavior

ASME pressure ratings: 150#, 300#, 600#, 900#, 1500#, 2500#

Higher class = Designed for higher pressure & temperature

Example: Class 150 may suit chilled water lines,
                Class 2500 needed for high-pressure hydrocarbon pipelines.

Heat Treatment & Manufacturing Grades

• Common forging standards: ASTM A105, A182, A350 LF2 etc. 
• Heat treatment improves:
  ✅ Strength
  ✅ Ductility
  ✅ Grain structure
  ✅ Corrosion resistance

HIC / NACE requirements critical for sour gas environments.

Tolerance & Machining Accuracy

Tolerances ensure perfect alignment with pipes & fittings:

• Bolt hole circle accuracy
• Thickness uniformity
• Straightness & perpendicularity to bore

Poor tolerances = Misalignment = vibration & leak problems

Coating & Corrosion Protection

Surface protection options:

• Hot-Dip Galvanizing (HDG)
• Zinc plating & epoxy coating
• PTFE / FBE coating for chemical pipelines
• Rust preventive oil coating

Required for marine & outdoor installations.

Flange Markings & Identification

Every flange must be marked with:

• Manufacturer name or logo
• Size & schedule
• Pressure class
• Grade & specification
• Heat number

Guarantees traceability for quality assurance.

Common Reasons for Flange Failure

• Improper gasket selection
• Uneven bolt tightening
• Damaged flange face finish
• Thermal expansion ignored
• Incorrect pressure rating selection

Proper QA ensures long service reliability.
