Thank you George for your valuable advice. If you see PG 10.2.2.3, it requires the documentation of killed steel. How to document whether the steel is killed or not, except mentioning the Silicon/Aluminium content. Is it possible to perform some tests?
Best Regards

Since the Code is Sect I + B31.1 you have to use PG-10. The approach is similar to UG-10. Since you lack full identification and If you know the spec of the materials then you implement PG-10.2 . If not then you implement PG-10.3. In both cases you have to perform chemical analysis and mechanical testsΣτις Τρί, 22 Σεπ 2020 στις 10:17 π.μ., ο/η Rejoy Thomas <rejoythomas90@gmail.com> έγραψε:--Dears,How can I recertify raw pipes, where the material certificates are missing/cannot be recovered..! The code of construction is ASME Sec I & B31.1. As per Sec viii UG-10, is it possible to recertify pipes that don't have certificates, by performing mechanical tests? Please share your knowledge with regard to this. Your reply would be highly appreciated.Best Regards
