Impact Testing on ASME B31.3 Process Piping - API 570 and API SIFE Exam Question

Bob Rasooli explains impact test requirement as per ASME B31.3 for process piping which is API 570 piping inspector and API SIFE (source inspection fixed equipment) exams questions.The video indicates how exemption evaluation should be conducted. The video describes that piping material grouped in 4 curves and exemption depends on the assigned curve, wall thickness, minimum design metal temperature. If material minimum design temperature and wall thickness combination fall below the curve, then the impact test is a mandatory requirement. If it falls on the curve or above the curve, then is exempted.

How did you define "stress ratio"? i am doubt!

How A106 Gr.b belongs to curve D

[@vinaymaisuriya3885]

Could you please explain for MDMT -40 F and pipe material SA-516 Gr.B. Pipe 6" NPS and SCH. 40. Design temperature 95 C and pressure 5 psig...

[@vipinzh]

Gr. B koi pipe nahi hota , lets assume A516 gr70 then it will fall under B-curve, temp95C hai toh thickness kuch bhi assume kroge impact test ki zaroorat nh hogi because curve upar ban rha hai

Can someone PLEASE help me to find a solution to the below problem?
Thanks in advance.
An A 381 Y 35 pipe is 1.0” thick and is installed in a system operating at 150 psi. A replacement pipe will be ordered, and will be the same material (not normalized or quenched/tempered). If the design minimum temperature is 10F and the nominal pressure stress is 10,000 psi, what temperature can this material be operated at without impact testing?

[@vipinzh]

min. of 20degree C, if stress ratio u will provide then maybe further can reduce
