Re: Am I reading this right?

If what you are saying is true, and I'm not questioning your statement, then this condition would not allow the lower obstruction to be the bottom chord of a steel bar joist or open web wood joist because the range pipe would need to be centered in the web of the joist and parallel to the joist,

RE: Am I reading this right?

Because an Upright ESFR sprinkler can be connected directly to a Range Pipe of up to 100mm NB thus it is tested with an obstruction to core discharge. The Upright ESFR sprinkler must have the yoke arms aligned with the Range Pipe therefore the obstruction is in the shadow area from the yoke arm

Is this pipe that is reasonable for the pressure? The only time I ever asked about this was use of that very lightweight plastic pipe you see on the lawn irrigation aisle at Home Depot. It's been awhile but when I asked the designers' if this pipe was rated for 90 psi in one case, and 110 psi in

What do you mean by out of control? Monthly or weekly runs? I’m still old school but I do wear full PPE (most of the time) during annual testing, even after 3 arc flashes. I know.. I do a flush, 4 points with everything, 3 manual, 3 auto, exercise both disconnects, full run handle, even light

The easiest solution we found when faced with this very problem was to call in the experts. When we asked our insurance agent about this we discovered that we could end up needing to change our policy to cover high voltage exposure. So we now use manufacturers recommended pump service compani

Lets assume he was typing too fast and meant to say that ESFR are NOT a control mode sprinkler. Upright ESFRs have a very different discharge pattern. The pendents have a very strong thrust zone in the middle of the pattern that play havoc with obstructions. Uprights do NOT. The penalty is t

There are upright ESFR sprinklers. They are K 19 (point something) and I believe they are metric and are popular in Europe. I could be mistaken about the metric part, but they are listed in the protection schemes for storage occupancy protection in NFPA 13 as ESFR. Mark at Aero 602 820-7894 S

Short story is yes. Long version is an ESFR is not an upright it's a control mode sprinkler and has its own rules. Beyond that if you are using them then you usually have an insurance underwriter who also had their own rules Sent from my Verizon 4G LTE Droid On Mar 27, 2017 6:54 AM, Vince Sabol
