Abstract

Under sponsorship of the Line Pipe Research Supervisory Committee of PRC International, Battelle has conducted ongoing research on the fundamental mechanisms driving failure of pipeline corrosion defects. This phase of the research investigation has resulted in a simplified, closed-form failure criterion for blunt corrosion, known as PCORRC. This report summarizes the key elements of recent research including: (1) development of a PC-software computational model, known as PCORR, for predicting the remaining strength of the class of corrosion defects that fail by ductile plastic-collapse under internal pressure loading; (2) a comparative evaluation of the material and defect geometry variables that control the remaining strength of blunt corrosion defects in moderate- to high-toughness pipe materials; (3) development of the simplified failure criterion, PCORRC, for predicting the remaining strength of blunt corrosion defects in moderate- to high-toughness pipe materials. The results of this investigation indicate that corrosion defects may fail by one of two potential failure mechanisms. The first is a ductile plastic collapse mechanism in which failure is controlled by the material`s ultimate tensile strength. The second is a fracture-based mechanism in which cracks may nucleate, grow, and coalesce at the base of the corrosion defect.

Failure Pressure Estimates of Steam Generator Tubes Containing Wear-type Defects

Conference Chang, Yoon-Suk; Kim, Jong-Min; Huh, Nam-Su; ...

It is commonly requested that steam generator tubes with defects exceeding 40% of wall thickness in depth should be plugged to sustain all postulated loads with appropriate margin. The critical defect dimensions have been determined based on the concept of plastic instability. This criterion, however, is known to be too conservative for some locations and types of defects. In this context, the accurate failure estimation for steam generator tubes with a defect draws increasing attention. Although several guidelines have been developed and are used for assessing the integrity of defected tubes, most of these guidelines are related to stress corrosionmore »« less
Database of corroded pipe tests. Final report

Technical Report Vieth, P; Kiefner, J

The remaining strength of corroded pipe is an important consideration in the operation and maintenance of high-pressure cross-county pipelines. In that pipeline replacement is extremely costly, pipeline operators need to avoid replacing pipe that, though corroded, is still fit for service. For over 20 years, the pipeline industry has relied upon a simple, reliable semi-empirical equation for predicting the remaining pressure-carrying capacity of corroded pipe. This equation is embodied in an industry-accepted standard, the ASME B31G Guidelines. The basis for the guidelines is found in past research sponsored by the Pipeline Research Committee (PRC) of A.G.A. The final acceptance ofmore »« less
A new design criterion based on pressure testing of torispherical heads

Journal Article Kalnins, A; Rana, M - Bulletin - Welding Research Council

Two vessels with torispherical heads were pressurized to destruction at the Praxair Tonawanda facility on September 12--13, 1994. The objective was to determine pressures at which observable or measurable indications of failure could be detected. Plastic limit pressures for the two heads were calculated at 190 and 240 psi, respectively. For Vessel 1, the only observable action was a slow formation of some waviness of the knuckle profile at approximately 600 psi. It lost pressure at 700 psi when a crack developed at a nozzle weld at the bottom of the shell. For Vessel 2, no indication of any signmore »« less
Research seeks more precise corrosion defect assessment; Part 1

Journal Article Stephens, D - Pipe Line Industry; (United States)

Heightened competition among energy suppliers is making cost-effective maintenance and rehabilitation decisions increasingly important. Accepted methods for evaluating corroded pipe's remaining strength, while sound and well validated, are semi-empirical and limited to specific corrosion defect classes. Key industry concerns on the effects of axial loads on defect behavior and on interaction of adjacent defects cannot adequately be addressed by the classical acceptance criteria such as ASME B31G. The industry, through the Pipeline Research committee (PRC) of AGA and the Gas Research institute (GRI), has recognized the need for improved understanding and behavior models of corroded areas in pipelines.

Techniques developed to evaluate the fracture toughness offast breeder reactor duct. [Use of J-integral tests]

Conference Huang, F.; Wire, G.

Large changes in strength and ductility of metals after irradiation are known to occur. The fracture toughness of irradiated metals, which is related to the combined strength and ductility of a material, may be significantly reduced and the potential for unstable crack extension increased. Therefore, the resistance of cladding and duct materials to fracture after exposure to fast neutron environments is of concern. Existing Type 316 stainless steel irradiated ducts are relatively thin and since this material retains substantial ductility, even after irradiation, the fracture behavior of the duct material cannot be analyzed by linear elastic fracture mechanics techniques. Instead,more »« less
