Please make video about Aramco engg std. Which is certainly useful for every piping engineer. I hope you are going to start such std very soon.

Excellent video. At 00:58 of the video, you mentioned that "serrated finish" is used for "non metallic gasket". But spiral wound gasket (metallic gasket) is used with serrated finish and you mentioned that metallic gaskets require smooth finish.
Would you kindly clarify it please?
Thanks.

Regarding spec break ...valve should always in higher spec so that upstream valve conditions i e pressure and temperature can be sustained

Please make a video on how to decide a joint to be field weld or shop weld when designing/ routing a pipe in software, thank you.

Excellent video! Regarding "Y" in pipe thickness formula, it is which coefficient? And there is nothing mentioned about material yield strength?
Can you clarify please?

Knowledgeble video, pls pdf copy if available i will pay the fees.

In one of the Interview question videos, it was told that Seamless pipes are used upto 18", but in this video it is 16"?

[Mindsoul]

In difference between pipe and tube, it was mentioned that pipe has constant OD but the tube has constant od with thickness mentioned in bmg. For pipe the OD never matches the called pipe in inches until above or equal to 12”. Please correct me if wrong.

Mam your video is very good but i understand very little. I want you to make videos in Hindi. If you make videos in Hindi, then more people will understand. Due to which more people will see your video and your members will also increase. Thank you🙏🙏
