The best thing you get an API5L,from American Petrol Institut.Cost will app. 115-120US-Dollars,you can order through internet adress is http:// www.api.org.
There is in inner and an outer N5-notch dim. are width 0.04" max,depth 5%t(nom. wall)+/-15% with a min off 0.012" +/- 0.002" ,length for ultrasonic is 2" for max depth.
Normally the test pipe will supply by producer(pipe mill),should be sam grade and weight.For weld normally a 1/16" hole will be used.
With best regards Andreas Voge
