High-density polyethylene (HDPE) piping has been used in place of steel alloys in the petrochemical, power, and mining industries due to its exceptional resistance to corrosion and erosion. Recently, HDPE has also been used for nuclear safety-related cooling water applications. The application of nuclear quality assurance requirements creates reasonable assurance that the production fusion join...

Comprehensive upgrades of gas turbine involve the replacement of “flange-to-flange” parts with more advanced designs. Because late-model gas turbines already incorporate advanced technology, these comprehensive upgrades apply only to older gas turbines that are part of a series or model line that the original equipment manufacturer (OEM) has redesigned. Examples of these model lines include the...

Joint kinematic behaviour, i.e., joint rotation and axial translation, can partially help pipelines to accommodate abrupt ground movements, cause leaking if service limit is exceeded, even without any structural failure. Kinematic behaviour of bell-spigot jointed ductile iron (DI) pipes its influence on sealing capacity under transverse movements are investigated in this study. Firstly, a beam-...

In this report, we present the case of a 64-year-old woman who sustained a Burch-Schneider cage fracture. Prior to this event, she underwent repeated acetabular reconstructions, but in the end prosthesis removal was performed as a salvage procedure. We believe that the primary cause of the fracture was metal fatigue facilitated by intraoperative re-contouring of the flange, as well as reuse of ...
