    Fouling Factors for PHE

    Thank you rmv! I'll take that in mind! But when you are evaluating a PHE working, against design, do you use the fouling factor?

    Fouling Factors for PHE

    That's what I was looking for! The values I need are only 20-30% of the normal Shell&Tube! It's very kind of you submitting the paper! Tks a lot!

    Steam - Tracing or double-pipe

    Duwe and ash, thank's for your input. About the expansion coefficients, we already took those in mind. Tha ash experience, might be very usefull for a decision.

    Steam - Tracing or double-pipe

    Big, My question is more about - would tracing be enough? So, I'm looking for something like: If process fluid solidifies at 90ºC, for a 3" pipe one tracing line/two tracing line/jacketed line/etc is enough. We have steam available and we also have some electric tracing available, but this last...

    Steam - Tracing or double-pipe

    Q:Do you require heating on the branch connection? A:Yes. But it was decided to let it traced. Q:How was the existing jacket terminated when you cut it for the branch connection? A:According to the site you mentioned, it was swaged jacketed piping. Q;Is the branch connection configured...

    Steam - Tracing or double-pipe

    DSB123, Yes, I meant jacketted pipe. And its not really a pipe-line, but it's a line with about 100 meters. The problem is that we have cut the pipes to put another entry in the line. In means the outside was cut off and we became without jacket in a small part of the line. So, I'm wondering if...

    Steam - Tracing or double-pipe

    For heating a pipeline with steam, is there a simple definition/procedure to decide the use of a double-pipe or tracing? Is there a site where I could read more of these (already tried a few, but didn't found what I'm looking)? Thanks in advance

    Demin. water - Cationic bed filtering laterals

    Well, the raw water come from underground. Its always at +-25ºC. The regenerant solution is a little bit higher. It may vary, lets say, 30+-5ºC.

    Demin. water - Cationic bed filtering laterals

    Hello! I have a problem with the filtering laterals (regeneration screen) inside cationic bed. They worn after 2 years of work. They are half-pipes (half is a common pipe and the other half is a screen with 300 microns openings) which contact with 3 fluids: 1 - Raw Water; 2 – Air; 3 – HCl...
