Abstract Failure cause analysis was carried out on tee joint crack of boiler platen superheater header (12Cr1MoV) of subcritical power station applying microanalysis,mechanical properties test,chemical composition analysis,metallography examination and SEM observation etc.Results indicated that the tee joint crack originated at the original defects,connected with reheat cracks during propagation and led3D analysis for pit evolution and pit-to-crack transition Corrosion fatigue has been found to be responsible for the degradation and failure of many metallic materials and structures (Ruiz and Elices,1997; Zupanc and Grumb,2010; Palin-Luc et al.,2010).A corrosive environment assists corrosion pit formation,pit evolution and eventually leads to fatigue crack initiation and growth to failure (Ishihara et al.,2008; 2010; Bhuiyan et al.,2008).

A failure analysis of fillet joint cracking in an oil failure analysis flange crack zhejiang pipe

Nov 01, 2009· The weld failure was attributed to three possibilities, including microbiological sulfate reducing bacteria from hydrotesting the tank with seawater (March and Mclennan, 1997). The crack of a flange on the south side of an oil tank at a Houston, Texas oil and chemical company in 2003 let the oil out and led a small fire (USCSB, 20002003).A failure analysis of fillet joint cracking in an oil failure analysis flange crack zhejiang pipeNov 01, 2009· The crack of a flange on the south side of an oil tank at a Houston, Texas oil and chemical company in 2003 let the oil out and led a small fire (USCSB, 20002003). The failure of the bottom portion of a newly fabricated tank containing hydrochloric acid at an Illinois lighting plant in 2001 was probably due to malfabrication ( USCSB, 2000 failure analysis flange crack zhejiang pipe

APPENDIX B Potential Releases and Pipeline Safety

: API 5L and other specifications and standards addressing the steel pipe toughness properties needed to resist crack initiation and crack propagation, and to ensure crack arrest during a pipeline failure caused by a fracture must be followed. Keystone must prepare and implement a fracture control plan addressing the steel pipeAnalysis and treatment of welding crack of 304 stainless failure analysis flange crack zhejiang pipeIn this experiment, the internal cooling water pipe was selected, and the connection method was flange connection. The internal materials of the inner cold water pipeand the flange are all 304 stainless steel, and a K-shaped groove is set at the specific weld position. During the overhaul, an obvious crack was found in the internal weld of the inner cold water pipe. After polishing it, a large amount of welding slag was found inside.

Analysis of Mode II Crack Growth Behavior in Spalling

The crack in spalling failure of steel making backup rolls propagates mostly in Mode II.Mode II crack growth rate (KII-da/dN) and Mode II threshold stress intensity factor range (KIIth for aBoiler Tube Failure Analysis is about Corrosion,Stress The first step in boiler tube failure analysis by AIS is to perform a visual inspection of the failed tube.Then make preliminary observations and make suggestions on how to proceed in the boiler tube failure analysis or heat exchanger tube failure analysis that fits your budget.

Brittle crack propagation/arrest behavior in T-joint

May 10,2015·In the case of a full penetration T-joint,the brittle crack was arrested if the steel plate used for the flange had a high K ca value in the range from 4900 to 7300 N/mm3/2.FEM analysis of the stress intensity factor K indicated that brittle crack propagation was arrested under the condition that the K value at the running crack tip was less than the K ca of the material.Cited by 14Publish Year 2011Author Srdan M.Bonjak,Miodrag A.Arsic,Nenad D.Zrnic,Zoran D.Odanovic,Milo D.Dordevic Failure Analysis of Bucket Elevator Conveyor Chain Failure Analysis of Bucket Elevator Conveyor Chain Links @inproceedings{Yin2018FailureAO,title={Failure Analysis of Bucket Elevator Conveyor Chain Links},author={Edward C.Yin},year={2018} } View PDF.Save to Library.Create Alert.Cite.Launch Research Feed.Share This Paper.

Failure Analysis of Flange Crack - Metal & Oil & Gas News

Flanges are generally used for parts transfer to facilitate disassembly and assembly. Flange pairs are fastened together by bolts. Pipe flange materials generally use Q235, equipment flange materials generally use 20 steel, 16Mn, 304, 316, 316L. In order to investigate the impact of the storage environment on the engine, the engine was stored in a relatively harsh and high temperature and humid South Coast.
