Tingkah laku kakisan keluli karbon API 5L X65 dengan kehadiran bakteria penurun sulfat (SRB) dalam persekitaran CO2 adalah dikaji. Uji kaji yang dijalankan bagi meneliti tingkah ujian kehilangan berat dan analisis permukaan. Spesimen didedahkan kepada medium kawalan (tanpa konsortium bakteria) SRB selama 10 hari aliran gas berterusan. Biofilem, produk kedalaman lubang terhasil dicirikan mikrosk...

Residual stresses (RS) in pipes welded by a fully automated friction welding process, called FRIEX, are investigated using the contour method (CM) and X-ray diffraction (XRD). Samples were produced self-developed equipment, which is based on interaction between consumable intermediate rotary ring two stationary pipe sections, varying loading rate applied during of API 5L B with an X65 ring. Mec...

Low-carbon steel is widely used in industrial pipelines, and corrosion studies are focused mostly on erosion-corrosion, its prediction control. In this paper, the rate pipelines modeled using a flow loop measured by linear polarization resistance method (LPR) 3-electrode setup for API-5L-X65 QT steel. Optical microscopy SEM conducted to examine surface of sample products. The effect NaCl concen...
