Lukies Flanges stands out as a top-notch manufacturer and supplier of Alloy 20 Threaded Flanges in Midland, delivering high-quality, corrosion-resistant solutions tailored for critical industrial piping systems. These threaded flanges come with internal threads, allowing them to be easily screwed onto pipes without the need for welding. This feature makes them perfect for situations where welding isn’t an option or for systems that require straightforward disassembly. At Lukies Flanges, we prioritize precision manufacturing and adhere to international standards. Our Alloy 20 Threaded Flanges boast exceptional resistance to sulfuric acid, chlorides, and pitting corrosion, making them a go-to choice in the chemical, petrochemical, pharmaceutical, food processing, and power generation sectors for safe, reliable, and maintenance-friendly connections.
Alloy 20 Threaded Flanges are crafted from a nickel-iron-chromium alloy that includes 32–38% nickel, 19–21% chromium, 3–4% copper, 2–3% molybdenum, along with trace elements of carbon, manganese, and silicon. This unique blend guarantees remarkable resistance to sulfuric acid, chlorides, and pitting corrosion. On the mechanical side, these flanges deliver a tensile strength of around 620 MPa, a yield strength of about 300 MPa, and impressive ductility and impact toughness. Their threaded design not only simplifies installation and removal but also ensures structural integrity, corrosion resistance, and dependable performance in demanding industrial piping environments.
