API (American Petroleum Institute) Plates
API 5L line-pipe grade plate for oil and gas service.
Overview
Material overview
It includes as-rolled, normalizing rolled, thermomechanical rolled, thermomechanical formed, normalizing formed, normalized, and normalized & tempered sheets and plates.
Requirements for API 5L X grades are stringent: particular attention is given to toughness tests for sour service and higher pressure and temperature classes, with sulphur content minimized (max 0.007% specified).
