Need review for pipe wall thickness calculation sheet for pipes under internal pressure 7

[Asisraja D]

Hi professionals

i am a project engineer and i did some calculations part for calculating wall thickness for pipes under internal pressure as per ASME B31.3.
i have attached the sheet here.

This is just my work to submit to all of you for a review on the steps involved here and the Units i used here whether right or wrong ?
if anyone cross check the work please you can download and try this at free time. Thank you for all of your support to keep curious of engineering as part of my life.​

Sir i haven't heard about the software used for this kind of calculation, anyhow thanks for introducing them for me.

OP,
You have gone wrong in two places:
1. 4.78 mm wall thk looks to be a non-standard pipe schedule - means you can't buy in the market.
2. t[sub]m[/sub]value must be equal or greater than t[sub]c[/sub].

correct these two and you should be fine.

Thank you sir for correcting the errors in my sheet.

OP,
You must go for either 30 Sch or 40 Sch pipe, depending on market availability.
