Abstract

The curved-wide plate (CWP) tests are frequently used for assessing the quality of pipeline girth welds. Despite a large number of CWP tests having been conducted at great expense over many decades, an industry consensus standard remains unavailable. Considerable effort at several research institutions is being focused on the standardization of test protocols. It is widely recognized that comparing results from CWP tests from different institutions is difficult if not impossible without accounting for all the possible parametric differences. This paper presents the procedural details recently used in testing X100 girth welds. The protocols cover (1) specimen design and dimensions, (2) instrumentation plan and data acquisition, (3) specimen fabrication and preparation, (4) preparing and executing the tests, (5) processing of raw test data and (6) post-test metallurgical examination. The evaluation of specimen deformation, flaw growth, and comparison of test data with model predictions are presented in a companion paper. Furthermore, CWP test data are evaluated in detail and compared to tensile strain models of the girth welded pipe in another paper.
