Boiler Tube / Tube Plate Weld Cracks - Boiler and Pressure ...

eng-tips› …› Boiler and Pressure Vessel engineering ForumSep 04, 2006· I have radial cracks that presumably are thermally induced in my aged boiler tube to tube plate welds. On examination of the bolier tube plate tube ends there w Boiler Tube / Tube Plate Weld Cracks - Boiler and Pressure Vessel engineering - Eng-TipsI strongly recommend that you get a boiler inspection company involved as the presence of the "white deposits" could mean major trouble in you boiler. Not wanting to sound too pessimistic, white deposits in an area of cracking in a boiler or steam system usually indicate the presence of caustic embrittlement. If you have such a case it will take some expertise to determine even if repair is possible. Can you comeback with your boiler operating conditions and water treatment?Based on the information in your post, your repair approach sounds correct. One question, are the boiler tubes rolled and seal welded or are the boiler tube welds considered strength welds (partial penetration) in the tubesheet? If the tubes are rolled and seal welded it is best to remove the entire defective seal weld and re-weld, do not perform local grinding and leave the remaining seal weld intact. You may need to actually apply a preheat to the tubesheet to drive out residual moisture in the tube to tubesheet joint. This is not going to be an easy weld to make because the tube to tubesheet joint will have crud that could interfere with welding. You will need to work around this problem. After all of the defective tube welds are repaired, I would only MPI. There is no need to perform a hydrostatic test. Check to make sure that the repairs are performed by an organization that has a valid Certificate of Authorization to Repair Boilers/Pressure vessels issued by the National Board of Boiler and Pressure Vessel Inspectors.This sounds like a firetube boiler. If so you probably have a build up on the waterside that allowed the tubesheet/plate to be become overheated and crack. We used to call them "firechecks",tough to weld repair as it is full of residue and the carbon may be cooked out. Suggest you tear all the tubes and check the sheets after a good cleaning. May be time to replace,esp. the rear one. You can try to weld repair and/or patch but just does not work that well. If you got to have it back on line fast,remove the leaky tubes,weld repair,use copper ferrules in the tubeholes,and retube. Check your blowdown procedure and the location of the blowdown fitting. Your water chemistry may need a look as well. A good boiler repair firm can handle this rather common repair.2One more thought---You may be able to reroll the tubes and get them to seal. It will be short lived and depends how bad you need this boiler. I would do a hydro to working pressure when I had it torn down. You may find weeps or other problems. If you plan weld repairs without removing the tubes---you are likey wasting your time.Unclesyd : I need to check some info and come back to you, thanks. Matengr & deanc : valuable comments, again let me come back to you Thanks AllUnclesyd: the operating pressure is 250lbs. Water treatment can be a problem but I don't think we have a high pH issue. Metengr: majority of the tubes are expanded and seal welded with the exception of the the stay tubes which have strength welds. I have defects in both types. Why don't you see a benefit of a hydro test? Futher info : the front tubesheet has expanded tubes only. Deanc: no obvious build up or carbon. What do I need to look for and what would cause the build up? ThanksThe build-up would be hard or soft scale on the waterside of the tubesheet. This is not uncommon on the back sheet. Scale of even .10" can cause enough overheating of the base metal around the tubes to decarbonize. If you have spider cracks from the tubeholes(LP or MT)that is likely the cause. They will crack through the seal welds. Try a "reroll" before you go further. Make sure you have someone whos knows what they are doing. Hydro at working pressure and if it leaks---you need to pull some tubes to really check this. Also check the seating area of the roll joint. If this is the case--weld repairs are seldom long lasting. Best to replace the sheet. Water treatment/enough bottom and surface blows will help. If you have poor water or lots of make-up,plus run your boiler hard you must have good water chemistry. Rear tube sheet beading/seal welds make the pull out value higher and keeps the tube ends from burning off. In a old boiler a "seal weld" seldom seals. If your hole is bad use a copper ferrule,a good (maybe old) boiler guy will know about this. Call a "GOOD" boiler repair firm--you will be glad you did and cheaper in the long run. Sorry you asked???? Have fun and let us know what you find.Thanks deanc

Dollar Plate - Boiler and Pressure Vessel engineering ...

eng-tips› …› Boiler and Pressure Vessel engineering ForumMar 25, 2007· Vessel heads are usually formed with one plate section. But when the head diameter becomes too large and you cannot use just one plate section, the head is fabricated in orange peel sections. The orange peel sections meet at a "circular plate" at the center of the head.PPVE, Vessel heads are usually formed with one plate section. But when the head diameter becomes too large and you cannot use just one plate section, the head is fabricated in orange peel sections. The orange peel sections meet at a "circular plate" at the center of the head. That circular plate is referred by others as the "dollar plate". Is the nozzle that needs reinforcement located at the center of the head?Another word for an insert plate which is much thicker than the local shell that it is being inserted in and butt welded to. Never hurt to ask. 99% of the engineering people at a vendor shop won't hesitate to answer your question, no matter how stupid it may seem to you and I. Those are usually the most enlightening questions.I agree with vesselguy's definition. They are used to thicken the shell locally, very often around nozzle necks when sufficient reinforcement can't be achieved by a repad, whether it's for area replacement of the nozzle or to help counter other mechanical loads such as pipe loads.Thanks very much for your comments, guys. In the context of the Vendor's offer, the locally thickened plate for nozzle reinforcement is the answer I need, although it's interesting that another explanation exists within vessel engineering for a similar but different application. Something for my spongy grey data bank (memory). Thanks again.PPVE, For a new vessel, I would rather prefer an insert nozzle like those in ASME VIII-1 Fig. UW-16.1 sketches (f-1) through (f-4) than a locally thick insert plate to compensate for nozzle reinforcement. I have only seen insert plates used in patching up holes in incorrectly located nozzles or in modifying nozzles in existing vessels. I am not saying insert plates (as nozzle reinforcement) cannot be used in new construction. It is just that in my few years of experience, I have not seen it done on a new vessel.We use the term "dollar plate" to refer to any large round plate, in several different applications, without reference to any particular weld detail. Ask if it's not clear. (Maybe it's called a Pound Plate or a Euro Plate elsewhere?) FYI- the old silver dollars were our largest coin- minted up until 1935, then for a few years in the 1970's.I've seen insert plates used on new construction typically for large nozzles with large loads. Most of the time a forging conforming to Fig. UW-16.1 (f1-4) will be cost prohibitive in large diameters, and the OD of the forging at the shell attachment will not be sufficient to handle the piping loads. Actually, I've seen very few such forgings in any size… Given a choice between an insert plate (the ones I've seen are typically rectangular, not circular) and a repad, I'll take an insert plate any day for a variety of reasons including strength/integrity (especially on a large repad one has to question whether the shell and pad are acting together) and inspectability (an external inspection using UT cannot "see" the shell thickness under a repad). jt1We use insert plates and insert nozzles essentially interchangeably on all new equipment. We trend to use insert plates on tanks and relatively thin wall PV's while insert nozzles are used on higher pressure PV's. Our use of inserts is driven by our processes, one is extremely corrosive and the other is high temperature cycle driven. The corrosive process likes crevices and will preferentially corrode nozzles by end grain attack. To mitigate the end grain attack we seal weld all penetrations to slow the corrosion and preventive the penetration of the space between the shell and the doubler plate. Another advantage of the insert plate is that is that the nature of our corrosion is intergranular. The product of IGC is a plethora of little notches in the shell that greatly enhances the the affect of any motion in nozzle. The additional thickness of the insert plate slows the process. In the high thermal cycle process the doubler plate acts as a heat sink causing a higher differential between the shell and the doubler plate and the plate and the nozzle proper.1Use insert plate por pressure vessels in lethal, corrosive or nucler service. 100% NDE inservice inspection is one of the reasons rhgFor nozzles in heavy wall vessels(greater than 2" thick) or for nozzles in high-temperature hydrogen service, would you recommend a locally thick insert plate to meet reinforcement requirements?
