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
