AI Technical Summary
Complex eddies and impacts caused by abrupt changes in fluid flow direction in high-temperature and high-pressure steam pipelines lead to localized stress concentrations, especially at bends where fatigue cracks or creep damage are prone to occur. Existing technologies, through material upgrades or local structural reinforcement, have failed to fundamentally optimize the fluid turning process and stress distribution.
The traditional large-angle single bend is equivalently decomposed into a combined bend segment composed of multiple continuous sub-bends. The steam flow path is optimized through fluid dynamics and stress analysis to reduce local peak stress and avoid material consumption.
It effectively reduces local peak stress in pipelines, ensures safe and reliable operation, reduces material costs, and extends pipeline life. It is suitable for newly built or renovated high-parameter units.
