Our stainless steel high pressure socket welding reducer hoops are precision-forged fittings designed to connect pipes of different diameters in high-pressure industrial pipelines. They provide secure socket weld or threaded connections, precise alignment, and excellent pressure resistance.
Manufactured according to ASME B16.11, BS 3799, JIS B2316, GB/T 14383 and other international standards, these reducer hoops are widely used in oil & gas, petrochemical, power generation, offshore, and industrial pipelines, where reliable high-pressure performance is critical.
Forged construction ensures high mechanical strength and durability
Suitable for Class 3000, 6000, 9000 high-pressure systems
Compact socket weld or threaded connection for easy installation
Reduces leakage risk compared to other connection types
Corrosion-resistant and suitable for high-temperature environments
CNC machining & precise dimensional control ensures reliable socket fit
