    Flexible Connections Between Above Ground Water Tank and Piping

    "metra-Flex" is a listed flexible grooved connection that I have used in the past at bldg expansion joints, floating dock separation, etc. spkreng, CET

    Waterflow Test

    close one of the outlets to get a correct pitot gage reading, I am not sure of the formula but just like getting a reading from the 4 1/2" outlet you have to adjust the pitot gage psi reading bt a coefficient multiplyer to get a correct gpm, not just double it or add together. spkreng, CET

    Exposed Piping

    no bid, designing, the owner is the installer - yes headaches galore...gonna go with sch. 10 galvanized as they won't go under the dock (scubba painter) to paint pipe and won't find breakage, leaks until it's used. spkreng, CET

    Exposed Piping

    I have a floating dock, several - actually 1400' long with 400' spurs, am doing a dry standpipe. question is rather than use galvanized pipe couldn't I just have it painted and meet the corrosion requirements, all grooved items are factory painted, metra-flex fire loop at all...

    Obstructions and calcing Specific Application sprinklers

    First off if the lower level spacing is the greater of the two or you are dropping down with say 1" lines you need to prove this pipe sizing. usually when in doubt I do an additional set of calc's. Now as to the stair, it is enclosed with a 2hr wall and door right, so it's a separate fire area...

    AutoCad M.E.P. and ribbon

    Travis, I didn't get into it real deeply, but I found it overwhelming, considering I've been using AutoCAD LT since like 1998, for piping it had alot of commands and symbols, and seemed to be geared for a nice 3D and cooridantion, however it's commands were stacked with alot of electrical and...

    Sprinkler O-Ring

    true, true that was in the early stages. 80's -then Central got bought out and Labor allowance became a conditional documented (lets say 1 yr arbitration) and most contractors rightly opted out as no pay no fix spkreng, CET

    Trapeze requirements

    Well I had nothing better to do..according to NFPA 13 2010 9.1.1.6.6 The ring, strap or Clevis installed on a pipe trapeze...just as in the 2002 edition as stated above, however the sizing of rods is absent... spkreng, CET

    Sprinkler O-Ring

    What gets me is even though the CPSC mandated a recall how did Tyco (the receiver of omega o ring heads from Central) get away with only providing replacement parts (heads) and not labor? A lot of companies I know of quit selling this idea as the owner (rightfully) wasn't going to pay twice for...

    Trapeze requirements

    I stand by the statement that 2 hanging points (on the trapeze) = enough to hang the main...SD2 what does it say in the handbook/appendix? and what you say is true than you are hanging a 2" trapeze with 6" rings all around right..someone sometime got into this and the listed hanging capability...

    Trapeze requirements

    welcome AZ, as of the 2002 NFPA 13 Handbook, which I love because it explains stuff like this. 9.1.1.6.5 Where a pipe is suspended from a pipe trapeze of a diameter less than the diameter of the pipe being supported, ring,strap, or clevis hangers of the size corresponding to the suspended pipe...

    Rack Head Spacing

    sorry 13, 2002. I have read the referenced report and also viewed FM Globals latest review on changing sprinkler classifications as well as their study that only pend. spkrs are really effective in high challenge fires, so I can only glean together an informed opinion as to the design basis...

    Rack Head Spacing

    So I should inform the owner that his property cannot be protected by a fire sprinkler system, because no one has accumulated data for his needs? If I had a tobacco farmer whom grows his plants on platforms 30' in the air with a 75' warehouse shell, I should tell him no tests have been done so...

    Rack Head Spacing

    Why an FPE, NFPA 303 references NFPA 13, 2002 edition. NFPA #303 Chapter 6, 6.3.4.4 the design of automatic sprinkler systems shall comply with the provisions of NFPA 13, for Group A Plastics stored on solid shelves. my concern is the rack head layout. On an aside why would I need an FPE the...
