... discoloration on the metal, avoiding the formation of black scale. It was also recommended that the scale and discoloration of the welds at the outlet and HAZs be removed by abrasive blast cleaning and that the interior of the completed tanks be passivated, using either 22% HNO 3 at 60 °C (140 °F) or 50% HNO 3...

...Abstract Abstract A newly installed pipeline leaked during cleaning prior to hydrotest at a pressure of approximately 400 psig. The intended hydrotest pressure was 750 psig. The pipeline was constructed from spiral-welded API 5L-X65 HSLA steel and was intended for seawater injection. Analysis...

..., in the real world this is not always possible. Samples of oil, grease, and loose debris should be carefully removed from all components, identified, and stored for future reference. The components can then be cleaned with a solvent that will not remove or obliterate any rust, oxidation, burnishing marks...

.... Refinements in welding procedures and implementation of preweld/postweld heat treatments were also recommended. All system components were abrasively blasted with ground walnut shells prior to inspection and selection of specimens. The intent was to provide a clean test surface without inducing any...

... generous allowances for deviation about a nominal thickness, whether in terms of thickness or weight. In addition, the rusting of the steel and the lifting of the mill scale can render subsequent abrasive blasting easier, rather than increase costs as is sometimes claimed. From the many investigations...

... damage of the worn products after the tribological process. Then, the article describes some examples of wear processes, considering possible transitions and/or interactions of the mechanism of fretting wear, rolling-sliding wear, abrasive wear, and solid-particle erosion wear. The role of tribological...

The corrosive atmospheres in which wire ropes operate are created by blast furnaces, cleaning tanks, plating...

For example, any band saw cutting, abrasive-wheel cutting, or burning should be done well away from the fracture initiation area. The fracture face should not be touched by any liquid and should be kept dry and clean. If the part must...

... and the heating of steam in a superheater or reheater. The heat-flow path through a clean boiler tube has three components. First, fire-side heat transfer from the flame or hot flue gases is by both radiation and convection. Radiation predominates in the furnace, where the gas temperatures may be close to 1650 °C...
