Stainless Steel Flanges
DIN 2573 Stainless Steel Flanges PN 6 are precision-manufactured flat flanges made from high-grade stainless steel, designed for low-pressure applications across a broad range of industrial sectors. Compliant with DIN 2573 standards, these flanges provide excellent corrosion resistance, mechanical reliability, and compatibility with standard piping systems. They are commonly used in non-critical, low-pressure environments in industries such as water treatment, HVAC, food processing, and general utility piping systems.
Ladhani Metal Corporation is a reputable manufacturer and exporter of stainless steel flanges, offering components that adhere to international quality benchmarks. The flat flange design simplifies assembly and disassembly, making these flanges a practical choice for systems requiring easy maintenance and reliable sealing at lower pressure ranges.
Pressure Rating:
• PN 6 (6 bar / 87 psi): Engineered for low-pressure systems where moderate sealing performance and corrosion resistance are essential.
Flange Types:
• Plate Flanges
Used in low-pressure piping systems for simple bolted connections with gaskets.
• Flat Face (FF) Flanges
Ideal for use with cast iron equipment or non-metallic gaskets to ensure uniform surface contact.
• Slip-On Flanges
Designed for ease of installation by sliding over the pipe and welding both sides for moderate sealing.
• Custom-Machined Flanges
Available in specific dimensions and stainless steel grades as per customer specifications and operational requirements.
