Bill Amend will present “Identifying Vintage and Modern Pipe Types in the Field,” as a webinar on June 1, 2021, at 9 am CDT.

There is increased interest among pipeline operators in using randomly selected samples of pipe to determine the characteristics of an entire pipeline segment.  As a result, it is important to be able to identify as many characteristics of pipe nondestructively in the field as possible so that conclusive determinations can be made whether all pipe is from a single population or are the exposed segments of pipe representative of multiple populations having different characteristics.  When multiple pipe populations are present the mechanical properties can be different, the vulnerabilities and threats to long term integrity can be different, and sampling plans may need to be modified.

In this 2.5 hour webinar, the participants will learn to use visual and nondestructive inspection to identify the manufacturing process used to make the pipe. They will also learn to decipher the meaning of some early vintage pipe features that can indicate which manufacturer made the pipe, whether the pipe was rehabilitated after prior service and reused in a new application, the features of various types of girth weld designs used since the 1920s, and how or if the girth welds were originally tested or inspected.  The types of pipe that will be addressed include seamless, ERW, lap seam, butt weld/fusion weld seam, three variants of seams made by A.O. Smith (arc welded, arc+flash welded, and flash welded), single side and double side submerged arc welded seams (SSAW and DSAW), and lap seam.

Bill Amend, P.E
Principal Engineer, DNV
Pipeline Integrity, Metallurgical Engineering, Materials Selection, Welding Engineer

Bill Amend has 41 years of experience performing pipeline integrity management, failure analysis, metallurgical engineering, and welding engineering services. His background includes 26 years working for pipeline operators (Unocal and Southern California Gas Co.)  before working for engineering services providers. He is currently Principal Engineer at DNV GL. He is a co-author of the ASME report CRTD Vol. 91 regarding field measurement of hardness to determine the lower bound yield strength of pipe and has managed and conducted various research projects for ASME, DNV GL, NYSEARCH and PRCI addressing the continued development and validation of methods for nondestructive determination of pipe properties, chemical analysis of steel, tensile testing, and characteristics of early vintage pipeline girth welds.  He is a registered professional Metallurgical Engineer in California and graduated from California Polytechnic State University in San Luis Obispo (Cal Poly SLO).
