▶️Piping flanges are essential components within all piping systems. A flange is a type of mechanical joint and is the second most common type of joint after a welded joint. Unlike welded joints, a flange can be quickly and easily assembled and disassembled.
Flange Types
The most common flange types are the:
- Blind Flange
- Slip-on Flange
- Socket Weld Flange
- Welding Neck Flange (also known as a ‘weld neck flange’)
- Lap Joint Flange (LJF)
- Threaded Flange (also known as a ‘screwed flange’)
Blind flanges are used for a wide range of pressure classes and may have all types of flange face.
Slip-on flanges are used for medium to low pressure classes and use flat or raised faces.
Welding neck flanges are suitable for a wide range of pressures, temperatures and NPS sizes; they are the most common type of flange within the oil and gas industry.
Socket weld flanges are used for smaller nominal pipe sizes, and low to medium pressures.
Lap joint ring flanges do not come into contact with the process medium. A stub end is inserted through the LJF and welded to the associated pipe; it is the stub end that comes into contact with the process fluid. Stub ends can be used for a wide variety of pressure classes and temperatures.
Threaded flanges are used for lower pressure and temperature applications. Typically, the NPS of a threaded flange is small (less than 4”).
The most common flange faces are the:
- Flat Face (FF)
- Raised Face (RF)
- Ring Type Joint (RTJ)
Flat face flanges have a large sealing area and are used for low pressure and low temperature system. Raised face flanges have a much smaller sealing area and are often serrated; this type of flange is used for medium pressure systems and higher. RTJ flanges have a small sealing area and use metal gaskets (hard gaskets); RTJ flanges are used for medium pressure systems and higher.
The most common flange surfaces are the:
- Smooth
- Serrated (which can be concentric or spiral [phonographic])
- Stock Finish
Stock finish surfaces are the most common flange finishing surface. Raised face flanges usually have a serrated surface. Flat face flanges have a smooth surface finish and are used for lower pressure applications.

YOU didn't mention any information about reduced flanges ( types- dimentions .. etc )
It's not all that often that the algorithm actually recommends a video I might actually enjoy like this...
working in the Oil&Gas industry since 6months and finally i understood why flanges are not just 2 slab of metals to connects pipes and valves together. Really appreciated the “make it simple” touch of the presentation while explaining everything completely.
😄5:43 could not stop grinning at the comparison here , these are moments that make my work place entertaining. Thanks for adding some glitter to this tutorial
Great courses, really enjoyed! Much appreciated!
Glad to hear that. Took me over six months to write the content for this course.
I was too much confused from 2 years but now i understand the whole phenomena very well.its a great vedio and i think many people like me will now understand flanges
Very well explained. I'll never have to worry about remembering the flange faces again.
Oh man, your work is truly awesome! Thank you so much for sharing this content.
You're welcome
So much information demonstrated in a beautiful manner
That was excellent. Absolutely fascinating. I was in hvac, so frequently saw slip on flanges. I recall the importance of welding the face and the neck of SO flanges. Although frequently, in the field, only the neck would be welded.
Been getting ready to the job interview while watching your videos, and now still watching after i got the job offer😊
This videos is freaking great! So much useful information!
So well explained!
Beautiful explanation and presentation as always 👏👏
Thank you so much all your videos are really helpful.hope you will upload a video of how the compressor works.
wow, this is brilliant!
Best video on flanges 👌👍 your way of thinking and teaching is superb,thanks a million.
Excellent! ... Very informative.
I've enjoyed all of your videos thus far. Personally I would have saved the seal joke and inserted a picture of myself when you said Stud. But who am I? You rock🤘
Good point. Will have to get that joke in the next video. The seal joke had to go in the video though, I just could not leave it out (I tried).
that was a perfect explanation , thank you ^^
Great explanation and very well structured. Thank you!
You're very welcome!
It's so interesting and informative.
Thanks a lot.
Thank you, this is one of the best basics in Mech field. Much appreciated.
You're welcome
What a great explanatory video on flanges and types 👌 Thanks for producing such an amazing and engaging content on engineering.
You're welcome
Can you tell me which software is this??
very helpful, thanks!💯👏
Fantastic video, thanks for creating!
No problem
Thanks for sharing ☺️ and very informative 👍👍👍
Wonderful as usual stay blessed sir
Thanks for this video 🤝
Great job Mr Piping Engineering applications
thanks sir this was a very informative video , I work in oil drilling and we use lot and many types of flanges, especially the types 6B and 6BX flanges for high pressure applications 5K, 10K and 15K psi. the sealing grooves are very small compared to the size of flanges thus allow the device to sustain high pressures.
a fine application of the P=F/S concept
I love how you explained that you must understand the concecpt. 🙂 i'm rookie, have no papers, but so passionate about engineering.
thanks this was a very informative video
Absolutely flangetastic video 👍👌
amazing, I found this chanel yesterday and I have been watching some videos and everyone of them are amazing for learnig new stuff and refreshing some concepts even.
Welcome aboard!
Great video
was very helpful thank you
Great Video, thanks a lot.
Thanks for watching
thanks for informative vidoes
Just amazing!
Thanks!
You're my hero.. Thank you. Very helpful.
You're welcome.
@@savree-3d how are you this good at explaining things?'
I really appreciate your courses Sir. It is very academic.
I need Sir in future, If you can give us some webinars about PID's (process and piping). Thank you sir
So helpful. Thankyou!
Glad it was helpful!
great video and presentation I will look at your courses
Awesome, thank you! courses.savree.com
I like this... thanks a lot... 🙏
Excellent channel. Keep it up
Will do
Excellent video! What software is that? The model looks amazing. Thank you. Suggestion: do a video on hydraulic fittings, hoses, adapters, etc.
Well explained sir.
5:40 seal 😆😆😂
That joke had to go in there
ISO를 실제 제품으로 볼수 있으니 공부하는 엔지니어들에게는 쉽게 이해가 되겠어요. 좋은 영상 입니다. 저도 열교환기 열정산 지식전달 유튜브를 운영하고 있는데 도움이 되셨으면 합니다~ㅎ
I realy like all of your videos ....and please I want the other video that locked to see and download it ......
What software is used to generate this model but also the rendered graphics? The surface finishes are next level realistic! Cheers
Main products: sealing gasket,gland packing,PTFE/graphite/asbestos products, ceramic fiber products, high temperature heat insulation and fireproof material.
Just came across this brilliant resource. Excellent content. Can I ask what software was used to create the amazing graphics. Really brings the content to life
We use screen capture and saVRee.com
thank you
No problem!
What software did you use to make those model sir, and how long will it take to reach such level of proficiency?
Lol...the seal was a fan of ur pun at 2:25.
just wowwwww
Hi Sir Good day. May I ask if I can use a Raised face type valve in flat face flanges?
Videos on actuators & expansion joints.... On different types of valves
Please
Nice
Thanks
Very intriguing, very informative. Can you please share the software name that you are using to view the 3D model?
Used screen recording software and saVRee.com
what software been used in this 3D modeling?
Which software is this??
I have seen plenty of threaded langed that ar welded
😊😊
Please drop ur udemy price to 500rs in india , i just earn 9500 rs as trainee engineer , couldn't spend more. Ur prices are not too high but u can help ppl like me to fight our conditions thats power of knowledge which can touch and change world for many !

The minute I clicked on this video, I fully realized how much of a nerd I am.
Vishwakarma was best engineer ever sir
you still not explained how tightening flange bolt
3:23 deeznuts..... I'm sorry
This voice sounds so familiar 😑, Engineering Explained?
Seal 🤣🤣🤣
Yet, any man is easily 5 times physically stronger than any woman of the same build. PC is BS. Let it go.
Thanks for the flanges
Which way around does the blond flange get installed? Is it the flat side agaisnt the gasket or the inner raised side against the gasket?
