Reducing Threaded Flange

At Metrade, we deliver precision-engineered reducing threaded flange solutions that ensure a secure, pressure-tight connection between pipes of different diameters without the need for welding. These components support a wide range of low-pressure and non-critical piping systems, particularly in environments where welding is impractical, restricted by safety or environmental guidelines, or limited by specific code requirements.

We offer a broad selection of materials, pressure ratings, and size combinations to meet diverse industrial needs. Each product follows strict international manufacturing standards, with full material traceability and rigorous quality checks that reinforce long-term reliability. Our ISO 9001:2015 certification reflects our commitment to consistent performance, and all reducing threaded flanges aligns with ASME, API, DIN, and other global specifications to deliver dependable results across various applications.

A Reducing Threaded Flange is a versatile pipe fitting designed to connect pipes of different diameters using a threaded connection, eliminating the need for welding. It features a larger outer diameter with internal threads of a smaller size, allowing easy attachment to a smaller pipe while maintaining a secure and leak-resistant joint. This makes reducing threaded flanges particularly useful in applications where welding is not feasible, such as in hazardous or high-temperature environments where sparks must be avoided. These flanges are ideal for low-pressure and non-critical systems that require frequent assembly and disassembly. Manufactured from high-quality materials such as carbon steel, stainless steel, and alloy steel, reducing threaded flanges offer excellent mechanical strength, corrosion resistance, and durability. They are commonly used in industries including oil and gas, petrochemical, chemical processing, and water treatment, providing a cost-effective and reliable solution for connecting pipes of varying sizes with ease and efficiency.
