Early Generation Seam Welds

This report summarizes the results of the project, which focus primarily on anomalies and material properties of lap-welded pipe, low frequency Electric Resistance Weld (ERW) seam pipe, and flash weld pipe. Limited data were available and are reported for early single submerged arc welds, double submerged arc welds, and high-frequency ERW. The main body of this report summarizes the development of the material-property database and summarizes the types of seam-weld anomalies identified in this program. It also provides guidance on analyzing seam-weld anomalies and makes recommendations for future efforts. Appendix A provides information on the material properties of early generation seam welds. While not extensive, this appendix provides a basis for estimating material properties and their variations. Appendix B illustrates many of the anomalies present in early generation seam welds. This appendix can be used by subject matter experts to assess the validity of various inspection techniques and as an aid in selecting and using integrity analyses. Additional work is needed to characterize typical inspection signals as a function of anomaly type and dimensions. The data reported here do not represent the full range of pipe manufactured and in use today. Continuing efforts are needed to obtain more complete material property and seam weld anomaly data for use by pipeline companies in their integrity management programs.
