API N80 or N80 Q&T (Quench and Tempered) - general purpose pipe manufactured to API specification 5CT

 

Our quality N80 metal casing tube has the same steel grade as the J55 form along with the K55 variety goods. All of them belong for the initially group of small steel grade. Our products can drop into N80-1 and N80-Q types. If our client has no desire, there'll be no flaw detection with the N80-1 style solution. The following table demonstrates the distinction between these two types from their visual appeal.

 

API Normalized N80 - lower-cost alternative to standard Q&T N80; pipe walls less than 0.500 inch; inspections, testing and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results conform to API SR16 and are lower Q&T N80

Notes: A lower-cost alternate to standard Quench and Tempered API N80 (partitions considerably less than 0.500 inch). Inspection, screening and dimensions are in accordance with API 5CT for quality N80. Charpy v-notch effect examination absorbed energy success satisfy API SR16 and are reduced than Quench and Tempered N80.
