DIN Blind Flanges (EN 1092-1 Type 05, DIN 2527): Largest Global Manufacturer, Supplier & Exporter from Mumbai, India

Introduction to Dipti Metal Industries' Expertise in DIN Blind Flanges

Dipti Metal Industries proudly stands as the largest global DIN Flanges Manufacturer, supplier, stockist, dealer, distributor, and exporter of DIN Blind Flanges from our base in Mumbai, India. We are recognized as a top worldwide leader for high-quality flanges. Our manufacturing capabilities, combined with our extensive global sourcing from trusted, certified partners, ensure that all products rigorously adhere to European standards, primarily EN 1092-1 Type 05 and DIN 2527. Our commitment ensures compatibility, safety, and superior performance across diverse industrial applications globally.

DIN Blind Flanges are solid disc flanges used to effectively terminate pipe ends, valves, or pressure vessel openings, providing a secure and leak-proof seal within piping systems. They are indispensable for pressure testing sections of a pipeline, providing a permanent cap, or allowing for future system expansion, particularly in installations following European engineering standards. Our extensive inventory includes a comprehensive selection of DIN blind flanges in various nominal diameters (DN 10 – DN 2000), pressure nominals (PN 6 – PN 160), and face types, compatible with a wide array of industrial materials. Our unwavering commitment to stringent quality control ensures that every DIN blind flange we supply meets precise dimensional and material specifications, providing robust and durable solutions for demanding industrial piping applications worldwide.

DIN Blind Flange Code Standards (EN 1092-1 Type 05 & DIN 2527)

Dipti Metal Industries supplies DIN Blind Flanges compliant with the leading European standards. The table below outlines key specifications for these flanges.

Notes:

• RF (Type B): Raised Face (most common, with concentric serrations for gasket).
• FF (Type A): Flat Face (gasket covers full face, often for cast iron flanges).
• RTJ (Ring Type Joint): Used for high-pressure, high-temperature applications with a metal ring gasket.
• PN (Pressure Nominal): Designates the nominal pressure the flange can withstand.
• DN (Nominal Diameter): Represents the size of the flange in millimeters.

European Material Grades & International Equivalents for DIN Blind Flanges

Dipti Metal Industries offers **DIN Blind Flanges** in a vast array of materials, ensuring compliance with global standards. This cross-reference table focuses on common DIN/EN material equivalents for various flange types, including blind flanges, facilitating seamless international procurement.

Notes:

• This table serves as a general guide for common material equivalents used in flange manufacturing. Exact chemical compositions and mechanical properties may vary slightly between standards.
• Always refer to the specific material specification (e.g., EN 10222-1 for forgings, EN 10028 for plates) and manufacturer’s data sheet for precise details relevant to DIN flanges.
• The presence of "–" or "Equivalent supplied" in a column indicates that a direct, widely recognized equivalent may not exist or that Dipti Metal Industries ensures the supply of a functionally equivalent material to meet project requirements.

DIN Blind Flange Dimensions, Pressure Ratings (PN) & Face Types

Dipti Metal Industries ensures that all DIN Blind Flanges strictly conform to the dimensional and pressure rating requirements of EN 1092-1 Type 05 and DIN 2527. This ensures perfect fit-up and leak-proof connections in European and international piping systems.

• Nominal Diameter (DN) Range: DN 10 to DN 2000 (equivalent to ½″ to 80″ for certain classes).
• Nominal Pressure (PN) Ratings: PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160. Each PN rating dictates the maximum allowable pressure at a given temperature.
• Common Face Types:
  • Type B (Raised Face - RF): The most common face type for steel flanges, featuring a raised portion with a spiral or concentric serrated finish for optimal gasket compression.
  • Type A (Flat Face - FF): The entire flange face is flat, often used with soft gaskets and for mating with flat-faced equipment or cast iron flanges to prevent bending moments.
  • Tongue & Groove: Features a matching 'tongue' and 'groove' face, providing a self-aligning joint and improved gasket containment, used in specialized applications.
  • Ring Type Joint (RTJ): Designed for high-pressure, high-temperature applications, utilizing a metallic ring gasket that seats into a machined groove.
• Drilling & Bolt Holes: Conforms to the specific DIN/EN standards for bolt circle diameter, number of bolt holes, and bolt hole diameter, ensuring interchangeability.
• Wall Thickness / Flange Thickness: Designed according to the PN rating and DN size to withstand specified pressures and stresses.

For detailed dimensions, tolerances, and bolt circle data, always refer to the latest editions of EN 1092-1 and DIN 2527 standards.

Applications of DIN Blind Flanges

Dipti Metal Industries' supplied DIN Blind Flanges are essential components in numerous critical industrial applications across Europe and worldwide, providing reliable system isolation and pressure containment.

• Oil & Gas Industry: For terminating pipelines, pressure testing sections, or isolating equipment in refineries, petrochemical plants, and offshore platforms.
