N80

General purpose pipe manufactured to API specification 5CT. Available in both standard Quench and Tempered API N80 and lower cost Normalized API N80 (walls less than 0.5"). Inspection, testing and dimensions are in accordance with API 5CT for grade N80. Charpy V-notch impact test absorbed energy results meet API SR16 and are lower in Normalized N80 than Quench and Tempered N80.
