Casting Defects and Repairs - Common Problem on New Construction Projects
|
Abstract:
This presentation describe nine case histories (many with multiple castings) where casting defects, rejections or repairs caused significant impacts to project costs and/or schedule. All these cases involved alloys, such as Cr-Mo low alloy steels, 300 series stainless steels or nickel-based alloys. The defects were detected during either installation or during plant hydrotesting. Three root causes have been defined, namely casting defects due to poorly designed molds or inadequate casting procedures, improper heat treatment and contamination from scrap. Various improvements are being tried, and some industry standards are being revised to add additional quality control and assurance, but more widespread application of these steps is needed.
