Fatigue Aspects of CRA Lined Pipe for HP/HT Flowlines

Abstract: Hydrocarbon exploration and production is moving into deep and ultra-deepwater to meet global energy demands. The industry is having, as a result, to face up to field developments with great challenges, including designing for a HP/HT product whilst also meeting sour service requirements. It has been a common practice in the past two decades to use pipelines with metallurgically bonded corrosion resistant alloys for such field developments. CRA lined (mechanically bonded) pipes are, however, … Show more

“…On the other hand, bending of internally-pressurized lined pipes has received much less attention. Full-scale experiments, reported by Toguyeni et al (2012) and Sriskandarajah et al (2013), investigated liner wrinkling under bending in the presence of internal pressure, in an attempt to prevent wrinkle formation. In those tests the level of pressure was 50% of nominal yield pressure.…”

“…1b a schematic of a pipe longitudinal cross section in the neighborhood of a girth weld joining two BuBi ® pipes. The ends of the liners are terminated with a seal weld and a 50 mm overlay weld (see [11,12]). The ends of the pipes are then beveled to accommodate the girth weld between two joints (for more on current welding procedures see [24]).…”

“…To understand the challenges and limitation of reeling lined pipe, several full-scale bending experimental programs have been undertaken during the last several years including a series of bending results from a Delft University group (e.g., [5][6][7]), by Cladtek [8,9], repeated bending over circular shoes [10], full-scale reeling simulations by Subsea7 and Butting [11,12] and others.…”

“…Figure 1 shows schematically the neighborhood of a typical girth weld joining two lined pipes. For BuBi® pipe, the ends of the liners are terminated with a seal weld and a 50 mm overlay weld (see [13,14]) while the pipe end is also beveled to accommodate the girth weld joining two joints (for more on current welding procedures see [25]). Thus, in this set up, the edge of the liner can be considered attached to the outer pipe.…”
