    Compare corrosion of 304Lss to 316Lss for SO2 and SO2 queous

    Yah I'm just going to have the piping re done to the recommended. Rather fix it now than face down time later. Thanks Everyone!

    Compare corrosion of 304Lss to 316Lss for SO2 and SO2 queous

    SO2 reacts with water to form sulfurous acid H2SO3, not H2SO4 sulfuric acid. It acts much differently than sulphuric which is often extremely corrosive to both 304 and 316. To form sulphuric acid the reaction is SO3 + H2O --> H2SO4. From reading I have seen that 316L is the standard to use on...

    Compare corrosion of 304Lss to 316Lss for SO2 and SO2 queous

    I recently had some pipe installed for an SO2 line but I made the mistake of having fittings for two different projects sitting next to each other. So when the contractor finished their work I noticed that they had mixed in a few 304Lss fittings with the rest of the project that was 316Lss. My...

    AC-ITT pump Curves

    Ya I agree that the 3196 is overall a better pump, but the 731+ did have some great advantage. The dynamic seal that is on the 731+ pump is great, better than the 3196. They even have a double dynamic seal, which isn't in the 3196 line to my knowledge. Thanks alot for the curves Ten!

    That would be awesome!

    AC-ITT pump Curves

    I have been searching for an Allis Chalmer's pump curve catalog for a while now, but it is impossible to find on the web. I'm mainly looking for a catalog with the discontinued pumps like the PS-Plus and 731+ pumps. Wondering if any one has a pdf of these they wouldn't mind sharing.

    Super Sonic Flow in Pipe

    Thanks everyone for your posts, helped alot with getting more familiarized with the compressible flow equations. Especially when I should assume adiabatic, isothermal.. and so on. I used the adiabatic fanno flow equation to solve for mass flow rate of the air. Kyle

    Super Sonic Flow in Pipe

    Sorry, I'm a little green on modeling flows for a compressible fluid, and having a hard time grasping it. Basicly I've been assuming the fluid is first incompressible to get the entering velocity of the fluid into the pipe. Next I iterated all my friction factors with the increasing...

    Super Sonic Flow in Pipe

    Working on finding the mass flow rate of air exiting a vent out of a softner column. The pressure inside the column is 84.696 psia which is then vented through a 3" pipe (about 35 ft in lenth) to a backwash tank which is at atmospheric pressure. I have tried solving for this using basic...
