Thank you all very much for your answers. Therefore, as a conclusion, if I use ASTM A335 P91, I´ll have to calculate the allowable stress values at design temperature not exceed the lower of two-thirds of SY and two thirds of Syt. But I think there is a reason for ASME not to use ASTM A335 P91...
I'm trying to determine the wall thickness of a pipe that has a design pressure of 15,000 psi at 700 F.
The specified material is ASTM A335 P91. I have to use ASME B31.3 chapter IX (defined by the owner). The problem is that ASTM A 335 P91 is listed only in Appendix A. Can I use the allowable...
Thanks for all the replies.
jojoyohan, you´re right, maybe I have to use piping and fittings custom built.
LittleInch, thank you. The version I have is B31.3 2016. I am trying to request the latest version for my company. However, in any version, ASME B31.3 allows the use of unlisted...
Thanks for all the replies.
We are designing a process plant, which the following are the main design conditions:
Pressure disign: 15000psi
Temperature of system: 0°C (32°F) and 200°C (400°F)
Fluids: Water and Nitrogen.
Estimated quantity: 2000m
I had selected the X70 and the X80, but to use...
Has anybody ever use the N80 or other API 5CT one to use as a line pipe? It´s possible?
I need a material that resist 15000psi at 400°F. There aren´t materials listed in ASME B31.3 (table A1 or table k1) that results in acceptable thicknesses.Does anyone have a sugestion?
Thank you KeVinNZ!
It´s difficult to find this factors.
I have another question. Has anybody ever use the N80 or other API 5CT one to use as a line pipe? It´s possible?
I need a material that resist 15000psi at 400°F. Does somebody have a sugestion?
I am designing a pipe line, based on B31.3 Chapter IX.
Design conditions:
P (internal design gage pressure) = 15000psi
T (design temperature) = 400°F
d (required minimum inside diameter of the pipe )= 5,125in
There is no material listed (table A1 or table k1) that results in acceptable...
