@article{(Open Science Index):https://publications.waset.org/pdf/4546, title = {The Significance of the Radiography Technique in the Non-Destructive Evaluation of the Integrity and Reliability of Cast Interconnects}, author = {Keshav Pujeri and Pranesh Jain and Krutibas Panda}, country = {}, institution = {}, abstract = {Significant changes in oil and gas drilling have emphasized the need to verify the integrity and reliability of drill stem components. Defects are inevitable in cast components, regardless of application; but if these defects go undetected, any severe defect could cause down-hole failure. One such defect is shrinkage porosity. Castings with lower level shrinkage porosity (CB levels 1 and 2) have scattered pores and do not occupy large volumes; so pressure testing and helium leak testing (HLT) are sufficient for qualifying the castings. However, castings with shrinkage porosity of CB level 3 and higher, behave erratically under pressure testing and HLT making these techniques insufficient for evaluating the castings- integrity. This paper presents a case study to highlight how the radiography technique is much more effective than pressure testing and HLT.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {7}, number = {1}, year = {2013}, pages = {36 - 41}, ee = {https://publications.waset.org/pdf/4546}, url = {https://publications.waset.org/vol/73}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 73, 2013}, }
