Dipti Metal Industries, as a leading global manufacturer, stockist, and supplier, offers a comprehensive range of flanges conforming to key EN standards, ensuring the best quality and compliance for a large variety of projects worldwide, particularly those requiring European specifications.

• EN 1092-1 (Steel Flanges):
  • This is the primary and most comprehensive standard for steel flanges within Europe. It specifies requirements for circular steel flanges with PN (Pressure Nominal) designations. It has largely replaced older national standards like DIN 2501, BS 4504, and AFNOR NF E 29.
  • Pressure Ratings: PN designations from PN6 to PN400, covering a vast range of pressures. We manufacture and stock flanges for the biggest pressure demands.
• Other EN Standards for Flanges:
  • EN 1092-2 (Cast Iron Flanges): Specifies requirements for cast iron flanges, which we also supply.
  • EN 1092-3 (Aluminium Flanges): Specifies requirements for aluminium alloy flanges, within our capabilities.
  • EN 1092-4 (Copper Alloy Flanges): Specifies requirements for copper alloy flanges, also within our supply range.
• Types of Flanges Covered: EN 1092-1 covers a full range of steel flange types, each designated by a Type number, all of which our manufacturing capabilities can produce:
  • Type 11: Weld Neck Flanges
  • Type 01: Plate Flanges (simple flat plates, similar to Slip-On)
  • Type 02: Loose Plate Flanges (used with stub ends, similar to Lap Joint)
  • Type 04: Loose Plate Flanges with Weld-Neck Collar (a specialized loose type)
  • Type 05: Blind Flanges
  • Type 12: Hubbed Slip-On Flanges (similar to ASME Slip-On)
  • Type 13: Threaded Flanges
• Material Specifications: EN standards specify precise material grades (e.g., P250GH for carbon steel, 1.4404 for 316L stainless steel) which are part of the harmonized European system. We select and process these materials in our manufacturing.

Our deep understanding of the comprehensive EN standards ensures that Dipti Metal Industries is a top global leader in manufacturing and supplying compliant flanges, providing comprehensive and dependable solutions for large-scale projects requiring European specifications worldwide.

Flange Facing Types for EN Flanges, Precision Manufactured

The flange facing is crucial for establishing a secure, leak-proof seal with the gasket. EN 1092-1 specifies various facing types, and we manufacture and supply EN flanges with the most common and effective configurations, ensuring precision engineering:

• Type A (Flat Face - FF):
  • Description: (Face plate) The gasket surface is in the same plane as the bolting circle face. Our manufacturing ensures perfect flatness.
  • Usage: Requires a full-face gasket and is typically used when connecting to cast iron flanges or other low-pressure equipment that cannot withstand the bending stresses caused by a raised face.
  • Applications: Low-pressure, non-critical services, often with non-metallic full-face gaskets.
• Type B (Raised Face - RF):
  • Description: (Face surélevée) The gasket surface is raised above the bolting circle face. This is the most common facing type in EN standards, precision-manufactured by us.
  • Usage: Designed to concentrate the compressive load on a smaller gasket area, increasing the joint's ability to contain pressure. Used with various non-metallic and metallic gaskets.
  • Applications: Widely used across almost all industries for general and medium-to-high pressure service.
• Type C (Tongue), Type D (Groove), Type E (Spigot), Type F (Recess), Type G (Male), Type H (Female), Type J (Ring Joint Face):
  • Description: These are matching faces (e.g., Tongue & Groove, Male & Female, Ring Joint) designed to contain the gasket and ensure precise alignment. We manufacture these with high accuracy.
  • Usage: Provide a more robust and confined gasket seating area, especially for specialized, high-integrity, or high-pressure services (Type J is for RTJ gaskets).
  • Applications: Used in critical applications where positive gasket retention and enhanced leak protection are required, such as in aggressive chemical environments or high-temperature steam lines.

Our comprehensive stock includes EN flanges, both manufactured by us and sourced, with these facing types, ensuring Dipti Metal Industries is the best source for optimal sealing solutions in piping systems worldwide. We are a top global manufacturer and exporter of diverse EN flange solutions.

  • We conduct PMI testing using state-of-the-art handheld spectrometers for all incoming raw materials and outgoing manufactured flanges. This verifies the correct alloy composition of each EN flange, preventing material mix-ups and ensuring grade accuracy throughout our manufacturing process.
  • This process is critical for maintaining material integrity, especially for stainless, duplex, and alloy steel flanges. We ensure complete material verification for all our manufactured products for our clients globally.
• Non-Destructive Testing (NDT):
  • Various NDT methods are applied to our manufactured flanges as per specific EN standard requirements and project specifications:
    • Ultrasonic Testing (UT): To detect internal discontinuities within the material, ensuring the integrity of our manufactured product.
    • Radiography Testing (RT): For volumetric inspection of welds (for Weld Neck flanges, Type 11) produced in our facility.
    • Magnetic Particle Testing (MPT) / Liquid Penetrant Testing (LPT): To detect surface and near-surface discontinuities on our flanges, critical for flange integrity and sealing surfaces.
    • Hydrostatic Testing: To verify the pressure-retaining capability of the EN flange assembly manufactured by us.
• Mechanical Testing:
  • Includes tensile tests, hardness tests, impact tests (e.g., Charpy V-notch for low-temperature service as per relevant EN or equivalent ASTM materials), performed on our manufactured EN flange material to ensure it meets specified mechanical property requirements.
• Corrosion Testing:
  • For corrosion-resistant alloy EN flanges (e.g., stainless steels, nickel alloys) that we manufacture, specific tests like intergranular corrosion tests are performed as per EN ISO 3651-2 to confirm resistance to aggressive environments.
• Certification & Documentation:
  • All our manufactured EN flanges are supplied with full Mill Test Certificates (MTCs) conforming to EN 10204 Type 3.1 and 3.2. This is crucial for international projects and reflects our commitment as a manufacturer.
    • Type 3.1: Certified by our manufacturer's authorized inspection representative, confirming compliance with order requirements.
    • Type 3.2: Independently verified by an authorized third-party inspection (TPI) agency (e.g., TÜV, Lloyd's Register), providing additional assurance for critical applications for our manufactured products and compliance with PED.
