ASTM A860 WPHY60 ASME B16.9 Concentric Reducer Shipped to US Pipeline Project
Long-distance transmission pipelines across the United States often demand high-strength butt-weld reducers capable of maintaining toughness in cold operating environments. Haihao Group has completed production and shipment of ASTM A860 WPHY60 ASME B16.9 concentric reducer for an American pipeline client, fabricated in SCH40 wall thickness with two size combinations for diameter transition on trunk pipelines.

This ASTM A860 WPHY60 ASME B16.9 concentric reducer batch includes 12″×6″ and 18″×12″ butt weld concentric reducers. Overall dimensions follow ASME B16.9, while the end bevel preparation for field butt welding complies with ASME B16.25. Manufactured from ASTM A860 WPHY60 high-yield carbon steel, these fittings must deliver guaranteed chemical composition and mechanical performance, with Charpy impact qualification at -46°C to resist brittle fracture under low-temperature service.
During forming and heat treatment, every ASTM A860 WPHY60 ASME B16.9 concentric reducer is closely monitored by our quality team. After thermal processing, sampling mechanical tests and low-temperature impact tests are carried out to validate the required toughness at -46℃. Our inspectors check overall length, taper profile, wall thickness and weld bevel geometry to meet ASME specifications, ensuring seamless fit-up during field pipeline assembly.
Full material certification and low temperature impact test reports are provided with each ASTM A860 WPHY60 ASME B16.9 concentric reducer. These documents satisfy the rigorous material traceability and third-party inspection requirements common for US oil & gas transmission projects. Additional NDT, custom marking and protective export packaging can be arranged for other reducer sizes or wall schedules.
