RE: Hanger Loading

I agree. The loads given on the data sheets have safety factors built-in. If for some reason you needed to do an engineering analysis of that hanger, you’d have to contact Tolco for the load at which it failed during testing. Ed Kramer Bamford Fire From: Sprinklerforum

Re: Hanger Loading

Mike is correct, Jerry.  That 5x+250 only comes into play when using a hanging method which isn't listed. *Ken Wagoner, SET *Parsley Consulting*** *350 West 9th Avenue, Suite 206 *Escondido, California 92025 *Phone 760-745-6181* Visit the website *** On

Re: Hanger Loading

I believe if you look at the wording of the standard the only time the phrase 5 times the weight of the water filled pipe plus 250 pounds occurs is in situations that require an "engineered" solution to hanging. EG multiple system supports, pipe stands outside the scope of NFPA etc. I can't

RE: Grounding Electrical Wire to Sprinkler System

Here's the NEC Code Section; 2017 NEC 250.104 Bonding of Piping Systems and Exposed Structural Metal. (A) Metal Water Piping. The metal water piping system shall be bonded as required in (A)(1), (A)(2), or (A)(3) of this section. (1) General. Metal water piping system(s) installed

RE: Grounding Electrical Wire to Sprinkler System

Correct cannot be used for "GROUNDING". However per the NEC all metallic water piping including sprinkler piping is required to be "BONDED". GROUNDING = Used to connect the building electrical system to Earth. Fire Sprinkler piping including Underground, FDC's etc are not considered ground

Grounding Electrical Wire to Sprinkler System

Where in NFPA 13 does it say that the sprinkler system can not be used to ground the electrical system? Thanks, Mike ___ Sprinklerforum mailing list Sprinklerforum@lists.firesprinkler.org

Hanger Loading

I'm doing this right? I'm looking at a Tolco Fig 200-2 hanger ring. The max load is 400lbs. 400 - 250 = 150 / 5 = 30lbs 2" sch ~5.13lbs This means if I use this ring I will have to space my hangers about 5'8" on center. Jerry Van Kolken Millennium Fire Protection Corp.

Re: Software

Mike, If you're taking what you think is 3x as long to design and coordinate a 3D system over a 2D system then you're not doing anything wrong - it just takes time. Sure these fancy software packages might make things easier but there is still a lot of work to be done over a 2D design.

I agree about being accessable thru ceilings. I just mentioned it as to describe what it is: not a mezzanine or deck area above the ceiling. I agree with the single (or two) sprinklers at the unit idea, was just looking for some backup. As said before, the information from this group, more than
