150 lb or 150 # is the term used to specify pressure class of the flange. There is no real correlation of this with actual pressure rating which is also a function of temperature. The pressure class starts from 150 and goes all the way to 2500. 150 lb & 300 lbs are the most commonly used flange pressure classes. In the video, at 7:25 there is a table that correlates pressure class to European classification of pressure (PN) and pressure rating at various temperatures.
What’s the difference between the lap joint and the flat faced. You held them both up but they look identical. How can I tell the difference between the two?
This is the video that I was looking for. All of the others videos showed me drawings; I want it for real!thank u so much! Keep going this way!
Good video.

great video!
very good explanation
Good video
Thank you for Morocco
It's very helpful,Thank's a lot.

Can you make the video for different loads and moments in the flange?
thanks
What do you mean when you say 150 lb?
150 psi is the rated working pressure for that flange at a certain temp. I believe it is somewhere 8 to 900 degree range.
good
what is PN number?
sushant kapoor we deal in flanges.. contact me on +918433699329
Close up shot is better
