Why Certification Does Not Always Equal Quality? A Case Study

Why Certification Does Not Always Equal Quality? A Case Study

HRSGs and power boilers are built by assembling large numbers of components, mostly by welding. Design choices in optimizing heat transfer against overall cost lead to configurations that aim to minimize the number of welds per square meter of heat transfer surface. In addition, fabrication of the modules is frequently subcontracted by the OEM for manufacture in regions where manpower is cheaper. The OEM becomes in effect an integrator of components built by others. How can Product Quality for pressure parts be assured in that context?
