Threaded Flanges
Threaded Flanges are specially designed pipe flanges with internal threads that allow secure pipe connections without welding. Manufactured from high-quality materials, they provide excellent strength, easy installation, corrosion resistance, and reliable performance for low-pressure, high-pressure, oil & gas, petrochemical, chemical processing, and industrial piping applications.
Overview
Threaded Flanges are industrial flanges designed with internal threads that connect directly with externally threaded pipes without requiring welding. These flanges are ideal for applications where welding is difficult, unsafe, or not preferred.
Manufactured using premium-grade materials and precision machining technology, Threaded Flanges provide excellent dimensional accuracy, mechanical strength, and leak-resistant connections. Their design allows easy installation, removal, and maintenance while maintaining dependable performance.
Veltronova Industries supplies high-quality Threaded Flanges available in multiple sizes, pressure classes, materials, and international specifications. These flanges are widely used in oil & gas pipelines, chemical industries, refineries, power plants, water treatment facilities, marine systems, and industrial piping networks.
