摘要: 介绍了HFW焊管水压失效处理流程，并结合实际生产情况提出具体的应对措施。分析认为：HFW焊管静水压试验失效涉及焊缝和原料两方面质量因素；若出现水压失效，首先借助断口形貌、金相组织、电镜分析及机械性能试验确定失效源头，再由失效原因及分布情况来决定复检范围，最终保证HFW焊管质量。

Abstract: Described in the paper are the processing flow of hydrostatic test failure of the HFW pipe， and specific countermeasures as proposed based on actual operation circumstances.Relevant analysis leads to the conclusion as follows.The said failure involves two quality elements，i.e.，weld and material.In case of the failure，the failure origin has to be firstly identified by means of fracture morphology and metallographic structure analyses，electron microscopic analysis and mechanical tests，and then based on the failure causes and failure distribution，the re-test scope is determined in a bid to ensure final quality of the HFW pipe.
