1. Which is the best method available & suggested for inspection of Corrosion Under Insulation in a chemcial process plant?
2. Is it advisable to coat the pipes, drains & vents lines of a hazardous piping system before insulating? how long the high temp coating survive normally.
3. To my...
Boiler in our case is a waset heat boiiler & is designed as per ASME Sect. VIII and not ASME Sec.I...!
Discussion porgressing w.r.t. ASME Sec.I...!
Would any one like to change the opinion now & comment..!
As a thumb rule of civil engineering, the maximum allowable defelction for wind design shall be 1 horizontal per 200 vertical.
Soon, I shall be trying an innovative method to measure the defelction in our 80 mtr. high steel structure. let me suceed , i will share
@ Mike Halloran,
Thanks for your attention ... "We" are Human Technocrats & "We" live on "The Earth" currently.
I would appreciate if you could help to throw light on the techncial issue mentioed & request not to read between the lines..!
One of the metallic structure approx. 50 mtrs. high, around the plant process equipment vibrates too much. We have doubt that deflection/ vibration is higher than normal & could be dangerous.
What could be the probable reasons ?
Any method to measure the deflection ?
How much deflection is...
Back to Basics...!
Can some one tell .. where i can get the comprehensive list of codes & standards likely to be used in a Ammonia-Urea fertilizer plant..!
Query may look silly .. however, to us it is very critical to know the correct standards to be procured...!
Thanks mrfailure
1. My query is whether a partly submerged truss is worse than a non-submerged truss from corrosion point of view??
2. if we coat the truss members properly will it help to reduce corrosion rates in partly submerged truss?
1. A Filter water tank of 18000 m.3 capacity, that is in service for last 20 years seen a sudden faiure of trusses supports.
2. It is fixed roof type tank. Plate material is IS226 M.S.
3. Some corrosion was also seen on trusses. as per design trusses bottom of approx. 200 mm was submerged in...
We have a water tank that stores water for plant process aswell as drinking purpose. the tank is rmajor repair.
We need to protect the inside of this tank and wish to use a good protective coating that would not affect the potable water quality also.
Please suggest is it allowed to apply...
Boiler tube leak is suspected in our plant.
Tubes are SA213 Gr.,T-11, 3.2 m thick and 38 mm OD (qty. 120 )
Tube sheet is SA387 Gr.11, 21 mm thick.
Boiler is high pressure.
Tube to Tube Sheet weld joint is strength weld.
We need to attedn thetube leak by plugging the leaky tube.
Is the...
Original Queries was whether all ASME Sect VIII designed vessels need U stamp & do the shell thickness vary on higher side if we opt for U stamping?
gr2vessels replied it well in the very 2nd post however later the post got diverted more towards to AI cost, which was informative as well.
The...
Thanx all .... froum coming to a uniiform conclusion...!
We have strongly asked our designer to clarify their version on the effects stated by them with U-stamp.
Lets wait what he replies.. i will share here...!
Good & healthy Debate... thanks to all... I am unquoting, what our designer mentioned us when we asked them to design our vessel with U-stamp.
Guys... my concenr would be more clear now...
