ASME B16.11 Reducing Coupling
ASME B16.11 Reducing Coupling Manufacturer & Supplier
ASME B16.11 Reducing Coupling is a forged steel pipe fitting manufactured in accordance with the ASME B16.11 standard. It is designed to connect two threaded or socket weld pipes of different sizes while maintaining a secure, leak-proof, and high-strength connection. These forged reducing couplings are widely used in high-pressure and high-temperature piping systems where pipe size reduction is required without compromising system performance.
The ASME B16.11 standard specifies the dimensions, pressure ratings, materials, marking, manufacturing, inspection, and testing requirements for forged socket weld and threaded fittings. Manufactured using premium-quality raw materials and precision forging technology, ASME B16.11 reducing couplings provide outstanding mechanical strength, corrosion resistance, dimensional accuracy, and long service life.
Our ASME B16.11 reducing couplings are available in various pressure classes, sizes, and material grades to meet the requirements of oil & gas, petrochemical, power generation, chemical processing, marine, offshore, pharmaceutical, water treatment, and other industrial applications.
