New tube materials in development

摘要

FOR energy-conducting tubes (oilfield, conduits and boiler tubes), the trend is moving towards higher-tensile alloys as preferred materials. Pipeline producers must operate their pipelines under increasingly harsh environmental conditions and at higher pressure, in high-tensile steel grades such as X80, X100 and higher. In addition, the trend in the large tube sector is moving towards thicker walls and increased resistance to low temperatures.
