DIN 2527 SS 321 Blind Flanges are specialized components used in industrial piping systems to close off the ends of pipes or equipment where no further connection is necessary. A blind flange is a solid, flat disc without a central bore, specifically designed to seal the open end of a pipe or a vessel. The DIN 2527 standard, developed by the German Institute for Standardization, defines the specifications for these flanges, ensuring that they meet high standards for dimensional accuracy, pressure tolerance, and mechanical strength. The SS 321 material, used for the production of these blind flanges, is an austenitic stainless steel known for its excellent resistance to high-temperature oxidation, corrosion, and scaling. The addition of titanium to this steel stabilizes its structure, making it suitable for environments where temperatures fluctuate or are consistently high. As a result, SS 321 blind flanges are frequently used in industries where both strength and resistance to harsh environmental conditions are paramount, including the chemical, petrochemical, aerospace, and power generation industries. By utilizing DIN 2527 SS 321 Blind Flanges, companies can ensure secure, long-lasting, and efficient closures for piping systems under challenging operational conditions. These flanges are essential in maintaining the integrity of systems exposed to elevated pressures and corrosive substances, ensuring the safe containment of fluids and gases. key Features of DIN 2527 SS 321 Blind Flanges: Material Composition of SS 321: Carbon (C): ≤ 0.08% Chromium (Cr): 17.0 - 19.0% Nickel (Ni): 9.0 - 12.0% Titanium (Ti): 5 times the carbon content, generally around 0.60% minimum, to prevent carbide precipitation. Manganese (Mn): 2.00% max Silicon (Si): 1.00% max Phosphorus (P): 0.045% max Sulfur (S): 0.030% max Pressure and Temperature Resistance: Operating Temperature: SS 321 can perform well in high-temperature environments, up to 900°C (1650°F) intermittently and up to around 700°C (1292°F) for continuous service. Design and Dimensions of DIN 2527 Blind Flanges: Pressure Ratings: The design of a DIN 2527 blind flange is primarily based on pressure class ratings (such as PN6, PN10, PN16, etc.), which denote the maximum pressure the flange can safely withstand. Bolt Holes: The number and size of bolt holes for DIN 2527 blind flanges are specified according to the flange's pressure class and size. The bolt pattern is designed to ensure a tight seal and accommodate appropriate bolt sizes for a given pressure class. Thickness: The thickness of a blind flange can vary depending on the pressure rating and size, with thicker flanges being required for higher pressure applications. Nominal Diameter: Blind flanges are available in various nominal pipe diameters (DN) ranging from DN10 (1/2 inch) up to DN600 (24 inches) or more. Types of DIN 2527 SS 321 Blind Flanges: Standard Blind Flange (Type A): A solid, circular flange used to seal the end of a pipe or vessel. Common for general applications.

A DIN 2527 AISI 4140 blind flange is a specialized type of blind flange made from AISI 4140 alloy steel, adhering to the DIN 2527 German standard. Blind flanges are crucial components in piping systems, used to seal the end of a pipe, vessel, or valve to isolate it or stop the flow of fluids. The AISI 4140 material used for this specific flange is a high-strength alloy steel known for its robustness and excellent mechanical properties, making it ideal for high-stress applications. AISI 4140, a chromium-molybdenum alloy steel, is renowned for its excellent mechanical properties, including high tensile strength, hardness, and resistance to wear. It is often used in heavy-duty applications such as in the automotive, aerospace, and oil & gas industries, where the need for robust materials is crucial. The use of AISI 4140 steel in a DIN 2527 blind flange ensures that the flange can handle high pressures, temperatures, and mechanical stresses without compromising on performance or safety. Material: AISI 4140 Alloy Steel Composition: AISI 4140 is a medium-carbon steel alloy that contains chromium (Cr) and molybdenum (Mo) as its primary alloying elements. These elements improve the steel's hardness, strength, and wear resistance. Key Properties: Strength: High tensile strength and yield strength, making it capable of withstanding high loads and stress in high-pressure applications. Toughness: Offers excellent toughness and impact resistance, making it suitable for challenging environments where forces are dynamic. Hardness: Can be heat-treated to achieve high hardness levels, providing resistance to wear and abrasion. Corrosion Resistance: While AISI 4140 is not as corrosion-resistant as stainless steel, it can still perform well in less corrosive environments with proper surface treatment (e.g., coatings or galvanizing). Design and Dimensions (DIN 2527) Shape: The blind flange is a flat, circular plate with no central hole. Its purpose is to seal the end of a pipe or vessel, effectively "closing" the pipeline or system. Bolt Holes: The flange has evenly spaced bolt holes around the perimeter, allowing it to be bolted securely to the corresponding flange or fitting in the system. These holes align with the bolt pattern of other components. Thickness: The flange thickness varies depending on the size, pressure class, and specific application requirements. It is designed to withstand internal pressure while providing a reliable seal. Pressure Rating: Flanges are typically rated according to pressure classes such as PN 6, PN 10, PN 16, PN 25, etc., indicating the maximum pressure the flange can safely handle without failure. Applications Pipeline Sealing: The primary function of a blind flange is to seal the open end of a pipeline, preventing the passage of fluids, gases, or other materials through the system. System Isolation: Blind flanges are used to isolate a section of the system for maintenance or repairs, allowing for safe disconnection of parts while maintaining system integrity. Pressure Containment: AISI 4140 blind flanges are also used in applications where maintaining pressure within a system is critical. The high strength and durability of AISI 4140 make it suitable for use in high-pressure environments. Types of Blind Flanges in DIN 2527 Raised Face (RF): The flange surface has a small raised area around the bolt circle to improve sealing when mated with a gasket. Flat Face (FF): The flange surface is level with the flange body, typically used with softer gaskets to create a seal. Ring Type Joint (RTJ): The flange may feature a groove to accommodate a metal ring gasket for high-pressure applications, providing a secure, reliable seal.

Commonly used for pressure testing, maintenance access, and future expansion. • Flat Face (FF) Flanges Flat sealing surfaces designed for use with full-face gaskets and flat-faced mating flanges. Promotes even bolt loading and effective sealing under high-pressure conditions. Carbon Steel Grades and Composition: ASTM A105 (Forged Carbon Steel) • Carbon (C): ≤ 0.35% • Manganese (Mn): 0.60 – 1.05% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.040% • Silicon (Si): 0.10 – 0.35% Applications: Commonly used for high-temperature and high-pressure systems. Ideal for oil and gas, steam, and hydraulic systems. ASTM A350 LF2 (Low-Temperature Carbon Steel) • Carbon (C): ≤ 0.30% • Manganese (Mn): 0.60 – 1.35% • Silicon (Si): 0.15 – 0.30% • Nickel (Ni): ≤ 1.0% Applications: Suitable for sub-zero temperature services such as cryogenic systems, LNG processing, and cold-weather pipelines. Applications of DIN 2627 Carbon Steel Flanges PN 400: • Oil and Gas Transmission Lines Used in pipeline systems and refineries handling hydrocarbons under high pressure. • Steam and Power Generation Plants Ideal for high-pressure steam lines, condensate systems, and boiler feedwater applications. • Petrochemical and Chemical Industries Suitable for handling neutral and non-aggressive chemical fluids and process gases. • Water Treatment and Pumping Stations Used in high-pressure water systems, including pumping stations, pressure regulators, and testing units. • Heating, Ventilation, and Air Conditioning (HVAC) Employed in high-pressure chilled water and steam systems for industrial facilities. • General Manufacturing and Engineering Systems Reliable for structural piping systems in factories and mechanical installations.
