Cast Iron Blind Flange
Product Introduction
Cast Iron Blind Flange is a solid, holeless flange whose core function is to seal the end of a pipe, isolate the fluid (gas, liquid, or solid media) inside, prevent leakage, and facilitate maintenance and repair of the pipeline system. Made from high-quality gray cast iron and ductile iron, using advanced lost foam casting and resin sand casting processes, and manufactured in strict accordance with international and domestic standards, cast iron blind flanges offer advantages such as simple structure, convenient installation, excellent sealing performance, high cost-effectiveness, corrosion resistance, and long service life. They can be directly adapted to various cast iron, carbon steel, and stainless steel pipes without additional modification, significantly reducing construction and maintenance costs.

Core Advantages
High-Quality Raw Materials, Controllable Quality: Cast Iron Blind Flange uses carefully selected high-purity cast iron raw materials, free of porosity, sand holes, and cracks. Rigorous chemical analysis and mechanical property testing ensure that the material's hardness, toughness, and corrosion resistance meet usage requirements. Fully Visualized Production: From raw material selection, casting, processing to finished product inspection, each process is controlled by professional quality inspectors to prevent unqualified products from leaving the factory.
Advanced technology and superior performance: Utilizing advanced lost foam casting and resin sand casting processes to replace traditional casting methods, the products have a smooth appearance, precise dimensions, neat edges, high machining accuracy, and evenly distributed bolt holes, ensuring uniform stress during installation and improving sealing reliability.
Standard compliance and wide adaptability: Strictly adhering to international standards ASME B16.1-2020 (standard for cast iron flanges) and ANSI B16.1, while also complying with domestic and international standards such as GB13295, ISO2531, and EN545.
