Hi all,
I would appreciate information on the water quality requirements for a once through heat recovery steam generator with steaaming conditions of 4140 kPag and 400 degrees Celsius.
Thanks

There is a carbon steel vessel with skirt (handling natural gas) that is electrically heat traced and insulated. The question is does the vessel require painting? If yes what type of primer and paint. My concern is that the paint must not impede heat transfer or burn fron the heat tracing.
The...
Hi everyone,
I am looking to substitute EPT rubber gasket with SS304 spiral wound gasket (with 99.5% graphite filling) on all piping flanged connections. I have read that there are quite a few cases of buckling of the metal winding and then finding their way into the piping. I was looking for...
Hi,
I have requirement to use 17-4PH stainless steel(Condition H1150) for valve stem.
I have an offer for HH1150 double age as per NACE MR-01-75 from a supplier. Can I use this instead?
I can't find the specification properties for HH1150, these are not listed in ASTM standards- do I assume them...
Hi to all,
An existing valve stem (Alloy steel 13 Cr.,1 Moly, HB-220-260) is to be replaced. The valve maintenance group prefer A564 Gr.630 (H1100)to be used.
1)I went through the ASME B31.1 Code and found that it is listed under Bolts,Nuts & Studs Austenitic. The max. allowable stress values...
Regarding pressure drop for flow through a tee the pressure drop factors given in Crane, Flow of Fluids is K=20fT for flow through run and K=60fT for branch.
I require clarifications on the following:
1)Is there any limitation on tee size for using the above. Say if I have a 10 inch. pipe with...
Hi:
I am looking to establish the flow resistance for a rectangular wire mesh strainer fitted in a lube oil tank to handle higher flow requirements.(The present strainer does not handle the flow requirement and there is a backing up.) I would like to estimate the pressure drop for different...
Hi:
I am looking to establish the flow resistance for a rectangular wire mesh strainer fitted in a lube oil tank to handle higher flow requirements. I would like to estimate the pressure drop for different screens. I would appreciate any help on formulae or correlation for this calculation...
