This ASTM A860 WPHY65-W eccentric reducer is sized 42 inch by 22 inch, with wall thickness 22.23 mm on the larger end and 12.7 mm on the smaller end. Unlike seamless variants, this unit is single seam welded, with the weld plate supplied as per the client’s drawing. Every production step was controlled to satisfy the mandatory Charpy impact criteria: 40J average and minimum 34J at -46°C, a critical requirement for pipeline systems that may encounter cold operating conditions.
Heat treatment is a core part of validating the ASTM A860 WPHY65-W eccentric reducer. The thermal cycle stabilises the welded microstructure, delivering consistent mechanical strength and guaranteed toughness across the body and weld zone. Once heat treatment records and impact test reports passed review, the reducer received a black paint finish for temporary surface protection before packing. Eccentric reducers of this grade are commonly specified for horizontal runs, helping prevent vapour pocket build-up at pump suction points on hydrocarbon lines.
MSS SP-75 governs high-strength butt weld fittings such as this WPHY65-W eccentric reducer, widely adopted across Middle East pipeline projects. Our quality team cross-checked dimensions, weld visual inspection, heat treatment documents and low-temperature impact test results before release. We also attach full material traceability and test documentation for the client’s site acceptance and third-party review.
Haihao Group regularly supplies MSS SP-75 high-yield fittings for UAE, Gulf region and global pipeline contractors. We support custom large-bore welded reducers, elbows and tees with specified Charpy impact values, heat treatment and coating options.
