DIN 2567 Carbon Steel flanges PN 25 and PN 40 are robust threaded flanges manufactured from high-strength carbon steel, engineered to perform reliably in moderate to high-pressure applications. Built to DIN 2567 standards, these flanges offer excellent mechanical strength, durability, and thermal conductivity, making them suitable for general-purpose industrial systems such as oil and gas, water pipelines, power plants, and mechanical construction. Ladhani Metal Corporation is a trusted manufacturer and exporter of carbon steel flanges, delivering components that meet stringent international standards. The threaded design ensures quick, weld-free assembly, making these flanges ideal for systems requiring ease of installation and periodic disassembly. Pressure Ratings: • PN 25 (25 bar / 362 psi): Designed for industrial systems requiring strong mechanical performance and resistance to moderate pressure and temperature variations. • PN 40 (40 bar / 580 psi): Suitable for high-pressure piping systems and fluid-handling applications in power, oil & gas, and manufacturing sectors. Flange Types: • Threaded (Screwed) Flanges Allows easy installation and removal, especially in systems requiring regular maintenance. • Raised Face (RF) Flanges Enhances sealing performance under elevated pressure and temperature conditions. • Flat Face (FF) Flanges Used in systems with flat mating surfaces, especially when brittle or non-metallic components are involved. • Forged Threaded Flanges Provide superior strength, resistance to impact, and tight dimensional tolerances. • Custom-Machined Flanges Available in various sizes, pressure classes, and carbon steel grades as per customer specifications. Available Carbon Steel Grades and Composition: 1. ASTM A105 (Forged Carbon Steel) o Composition: • Carbon (C): ≤ 0.35% • Manganese (Mn): 0.60 – 1.05% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.040% • Silicon (Si): 0.10 – 0.35% o Applications: Widely used in oil and gas piping, power generation, valves, and fittings due to its high strength and ease of fabrication. 2. ASTM A350 LF2 (Low-Temperature Carbon Steel) o Composition: • Carbon (C): ≤ 0.30% • Manganese (Mn): 0.60 – 1.35% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.040% • Silicon (Si): 0.15 – 0.30% o Applications: Ideal for low-temperature service in pressure vessels and pipelines, especially in cryogenic environments and cold climates. Applications of DIN 2567 Carbon Steel Flanges: • Oil & Gas Industry: Used in upstream and downstream operations, including pipelines, pressure vessels, and refineries. • Power Plants: Installed in high-pressure steam lines, water supply networks, and heat exchangers. • Water and Wastewater Systems: Suitable for potable water lines, sewage treatment, and distribution systems. • Chemical and Petrochemical Plants: Used in process piping systems carrying non-aggressive or mildly corrosive fluids. • Mechanical and HVAC Systems: Common in industrial construction for heating, ventilation, and air conditioning systems. Key Features: • Conforms to DIN 2567 standard • Available in PN 25 and PN 40 pressure ratings • High tensile strength and impact resistance • Cost-effective solution for industrial and utility systems • Threaded design enables non-welded, easy assembly and maintenance • Suitable for welding, galvanizing, or surface coating • Supplied with test certificates, quality documentation, and full traceability Conclusion: DIN 2567 Carbon Steel flanges PN 25 and PN 40 from Ladhani Metal Corporation are engineered for strength, affordability, and versatile performance. Ideal for use in industrial piping, mechanical assemblies, and infrastructure projects, these flanges deliver long-lasting service and simple installation.
