In high-chromium ferrite heat-resistant steel pipe welds, which are often used in ultra-supercritical pressure boilers Japan, a large number of Type IV creep voids occur the region deep beneath outer surface and then develop into cracks. When crack is detected, main piping power plant judged to have zero remaining life. Since damage areas material there no non-destructive evaluation (NDE) metho...

Piping systems are exposed to many negative effects during their operation, which often cause the occurrence and development of various erroneous states that significantly affect safety economy other operations. Therefore, it is important test implementation effectivity technologies could be suitable used repair these pipes or components without system operation shutdown as presented in this ar...

© 1989 Johnson Controls, Inc. 1 Code No. LIT-351H110 The relationship between the many factors which influence the pressure and flow rate within a hydronic system can sometimes seem very confusing. This report provides a simple systematic approach for analyzing basic hydronic systems. These concepts can later be applied to more complicated systems like those discussed in Engineering Reports H11...

In this paper we propose a new argument in support of the view that focus association involves covert focus movement with pied-piping, as proposed by Drubig (1994) and more recently supported by Krifka (2006) and Wagner (2006), and against the more prominent approach which does not involve movement (Rooth 1985, 1992). The evidence will come from an interaction between the interpretation of pied...
