Sulfide stress cracking resistance of API-X100 high strength low alloy steel in H2S environments
Sulfide Stress Cracking (SSC) resistance of the newly developed API-X100 High Strength Low Alloy (HSLA) steel was investigated in the NACE TM0177 "A" solution. The NACE TM0177 "A" solution is a hydrogen sulfide (H2S) saturated solution containing 5.0 wt.% sodium chloride (NaC1) and 0.5 wt.% acetic …

Studies of Environmental Stress Cracking of High Density Polyethylene Liner in Alkaline Surfactant Polymer Enhanced Oil Recovery Floods
… (HDPE) pipes in EOR process, environmental stress cracking (ESC) poses a threat to the integrity of the pipe in ASP floods. In this research, the ESC behaviour of HDPE pipes was studied in ASP floods under conditions that simulated the EOR reality. Particularly, tensile tests were conducted …

Solvent induced microcracking in high performance polymeric composites
The first paper, “Dye Penetrant Induced Microcracking in High-Performance Thermoplastic Polyimide Composites”, studied the possibility of spurious microcracking in three high-performance thermoplastic polyimide composite materials due to zinc iodine dye penetrant. The material systems were …

An assessment of the performance of high density polyethylene copolymers for natural gas distribution pipes
… the major influences being in the long-term hoop stress resistance and the environmental stress cracking resistance. Minor amounts of hexene-1 are more effective than comonomers lower in the homologous series, although there is some sacrifice of density related properties. A synergistic …

Potential for electrical power generation from dry geothermal sources
… the fissure geometry created by thermal stress cracking in a hydraulically fractured well. The fourth geometry modeled a cylindrical well bore. In the analyses, heat transfer in the rock and the thermal efficiency of a heat engine were considered in determining the amount of electrical …

Long Term Health Monitoring of Anthony Wayne Bridge Main Cable with Acoustic Emission Technique
… (NDT). AE events generate a spectrum of stress waves starting at 0 Hz, and typically falling off at several MHz . Based on the characteristics of AE waveforms and wave propagation theory, useful information like source location and the cause of emissions can be obtained. During the course …

Effect of intermediate solvents on poly(ether ether ketone)
… isotactic polypropylene. PEEK specimens were stressed in the inside of glass cones and immersed in a series of solvents. Differences among solvent uptakes of stressed and unstressed specimens were explained in terms of crazing and SINC. Microtensile tests were performed on completely swollen …
