Very informative video and interesting methods shown. Thank you for posting this video. It’s cool to see how all of the techniques and stuff is executed.
Thank you Brother.
Actually terrible
Great video. What references would you recommend for determining the minimum required size beams needed for the stiffeners? API 653 doesn't seem to cover much beyond stating they may be required.
Thank you bro. As you told, minimum size is not mentioned in the cods. Structural size depends, the diameter, slope, loads on the roof, ind speed etc
Superb good job 👌👌👌👍👍👍
Thank you.
hi this is interesting ,is there a course that i should to be a certified storage tank repair
Sorry, Bro. To my knowledge, I don't know any institution conducting certification courses for tank repair.
@@technicalstudies. okay thank you so much
What a great work 👌
Thanks a lot 😊
wonderful video
Thank you Bro.
What cutting method was used to cut the old annular away so that there was a clean straight profile on the bottom of the shell plates for welding the new annular welds. Are there photos of this work somewhere? You must also take care not to cause a differential settlement situation or cause damage to the shell bottom plate when driving in wedges. Interesting approach.
We used the gas cutting method, fortunately, our gas cutting technician was highly experienced in these types of jobs. He put a 10 thick flat bar near the corner welding and moved the cutting torch horizontally. The cutting was very smooth. Unfortunately, there was not any photograph left.
Great thanks, great thanks, great thank.
Thank you.
API 650 is for constructing a new above ground liquid storage tank while API 653 is for the maintenance of an API 650 to determine whether the tank fit for continued service.
Bro, you are right, but for some corrections, API 650 stands for atmospheric pressure. API 653 stands for whether the tank fits for continued service. Thank you for the comment.
Great work
Thank you.
Thank you soo much
You're welcome!
Informative
Thank you.
How to apply RT on weld seams joining annular plates together ?
I am sure, you know the answer. Mostly the client will not ask you, when you repare and replace the annular plates.
Amazing 👍🏼
Thank you
Thanks for this
Thank you.
super bro
Thank you Bro.
What is the correct scissor seal installation method in floating roof storage tanks for hydrocarbons?
Bro, sorry for the late reply. Each and every sealing has its advantages and disadvantages. I am only a fabrication engineer.
It is not clear on removeal of the existing annular bottom plate when wedge load is exerted on existing plate , also tnak height is reducing by 25 mm , will changes the position of nozzles
Superb
Thank you.
how do you perform the weld where the 2 annular plate is directly below the shell?
Thank you for the comment.We used to push two wedgs on both side of the joint between the shell and annular plate, making a gap of 20 to 25mm.
@@technicalstudies. How to do RT for Annular joints
@@TheTanker_69 Hai Ketsana. Not many clients, ask for RT, in this type of replacement methods. Instead, UT and PT is possible. In case the client ask for RT is a must, then we need to change the LOW COST to HIGH COST jacking method. Thank you.
@@TheTanker_69 where do you keep film for RT
More vids please
Sure Bro.
So you have to raise the tank with crane or hidraulik pistons
Bro. it depends on your pocket 🤣
If you have dollars, I will recommend the jacking method. This is a low-cost method.
Yes but if the tank weight is 120 tons, is not so safe to lift it with crane right ?
If your tank has a false button can you use this method
Bro. I dont understand what is false bottom.
How you remove the existing annular plate with bothe side welding
Bro. Annular plates, always welded on a single side.
Top side only.
How to weld annular to annular But Joint while Shell plates rest on Annular plate??
drive, wedges, between the shell and the annular plate, you will get enough gap for welding, use a needle grinder for cleaning.
Tank repair due to corrosion... have a ceiling
I will Bro.
Great work
Thank you.
great work
Thank you.
