Petrochemical refinery fertilizer plant heat exchanger in service vortex detection system

Petrochemical refinery  heat exchanger in service vortex flaw detection and thickness measure

Petrochemical plant  heat exchaner in service vortex flaw detection and thickness measure

Petrochemical refinery fertilizer plant heat exchanger ,heat exchanger tube mostly are carbon steel  or austenitic stainless steel

Austenitic stainless steel tube in service vortex flaw detector adopts normally used vortex detection method,interpolating probe  one by one stretches tube by worker or probe propeller to do flaw detection and tube wall uniformly reduced and measured

Carbon steel in service vortex flaw detection adopts far field vortex method to do vortex flaw detection on inner outter wall of steel tube and tube wall thickness measurement。

Vortex detecting workers apart from  detect out of hauge flaw tube for user to block pipe,they still need to evaluate last life of tube without out of gauge flaw,providing evidence for users to improve technology

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。
