Abstract

Over the past 30 years, severe demands have been placed on the pipe manufacturer with respect to the development and processing of materials to pipe line. Line pipe steel is put to extremely severe conditions like deep water, cold climate, corrosive and high pressure applications etc. Their quality requirements are becoming exceptionally stringent with respect to metallurgical properties i.e. cleanliness, physical and mechanical properties etc. In line with these requirements, significant improvements have been undertaken for achieving the desired chemistry and bringing down the level of non-metallic residuals to meet stringent specifications of customers. This paper briefly summarizes the technological requirements of line pipe steel.
