22/03/2011· The shear stability of an oil is measured by using both ASTM test methods D445 and D5275. First, the viscosity of an engine oil is measured. Then, the oil is exposed to severe shearing conditions by repeatedly pumping it through a specially-sized diesel fuel injection nozzle at high pressure. After shearing the oil, its viscosity is measured again.
07/09/2017· The mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high-Nb X80 pipeline steels with the different alloying systems have been used in the Second West-to-East Gas Transmission Pipeline Project. Nevertheless, an investigation into the effects …

With the rapid development of oil industry, the high strength-toughness drill pipe suited to the task of sour environment and ultra deep wells would be considered more and more important. A new drill pipe steel, which was designed with the proper decrease of C content and increase of Cr, Ni, Mo, Nb and V alloy element, was developed and studied in this study.
02/10/2008· The crack arrestability for high strength line pipe steels with tensile strength of 650 to 850 MPa was evaluated using precrack DWTT (pc-DWTT). Moreover, the effects of microstructure and texture on pc-DWTT energy were investigated. The pc-DWTT energy was remarkably affected by tensile strength.

Due to the requirement to develop a deep sour gas field (>2% H2S at reservoir depths of 5,500-6,000 m), it was decided to investigate the actual damage that high-strength drill pipe (S135 grade) will suffer when exposed to these formation fluids over a short time (1-3 hr), as it would be typical for circulating out the kick during a well-kill
This is termed as the phenomenon of Thermal shakedown. The material selected for high temperature and high-pressure piping should be resistant to corrosion at higher temperatures. As the temperatures increase in high-temperature piping systems, the insulation thickness is increased. Also at temperatures of the order of 650-700 degree C, Ceramic
