Product Overview
Engineered for durability and precision, our carbon steel pipe flange is manufactured using investment casting technology to ensure leak-proof performance, high-pressure resistance, and seamless integration in industrial piping systems. Designed for oil & gas, chemical processing, power generation, and water treatment applications, this flange guarantees reliability under extreme temperatures and corrosive environments. As a leading investment casting foundry, we deliver ISO-certified, customizable solutions tailored to meet global engineering standards.
Key Features
High Strength & Durability: Made from AISI 1045/1050 carbon steel for superior load-bearing capacity and impact resistance.
Precision Investment Casting: Tight tolerances (±0.2mm) ensure perfect alignment with pipes and valves.
Corrosion Resistance: Optional coatings (zinc, epoxy, or galvanized) for harsh or humid environments.
Customizable Designs: Adjustable flange types (weld neck, slip-on, blind), pressure ratings, and bolt patterns.
Cost Efficiency: Near-net-shape casting reduces machining time and material waste.
