Steam power plant turbine blade in service vortex flaw detection

Power plant turbine blade crack detection

Steam power plant turbine blade in service vortex flaw detection usually adopt edge probe to scan crack on the edge of blade,spot probe detects crack in root of blade。field operation needs to overcome affects that blade cavitation pitting  on crack detection.

Flow detection uses offline or online to detect surface of metal bar,tube,seamless tube,welded pipe and belt materials,near surface 、inner surface and inner flaw usually adopt outside wear probe,the detected material cross probe and detect;high frequency welded tube online vortex flaw detection can also adopt  saddle magnetic saturation、saddle probe to detect quality of welding line,including  lack of fusion、slag inclusion、sand hole、air hole、and other flaws.

When material area is big or shape is complex with high requirement,then it needs to adopt spot probe,manual or equipped with automatic scanning equipment to realize one by one scanning detection。

Different detecting ways need to adopt different auxiliary equipment,or suitable for situation,fully take advantage of current equipment of production scene ,design special auxiliary instrument to realize。for liquidity scene,usually adopt simple convenient auxiliary instrument to realize,manual way is available。
