Hi all,
Your considered advice would be welcome on the following:
We have Power Plant with a huge Gas Oil Storage Area with Cooling Systems giving a demand of around 25000 USGPM, this demand is supplied via 5 No. 20% Duty Fire Pumps.
Supplied from the same Underground Ring Main we have...
Hi All,
Could someone please advise if there any NFPA requirements for Hydrostatic Pressure Testing of the Fire Pump Suction Piping?
Is it subject to the same requirements as the "system side"?
I am aware of the code requirements regarding test pressures in NFPA13, but do these apply to the...
Gentlemen,
Your assistance would be appreciated please, the above clause in NFPA 20 states that the Jockey Pump stop point should equal the churn pressure of the Pump plus the minimum static supply pressure, I have a 10m High Fire Water Storage Tank, I have an 8" Outlet on the Tank and 8" Inlet...
Hi All,
Could someone please advise if it is a code requirement within NFPA 20 for the Jockey Pump and it's Controller to be located in the same room as the Fire Pumps.
As you can probably guess I have space issues!
Cheers

Hi all,
Hope you can help me, I have clients engineer who I need to convince that we have to have a dedicated and separated power supply to our Auto Change Over Switches from the Alternate Supply, I know this and I have provided the details in figure A.10.8, question is:
Does it clearly state...
Hi all,
I have a requirement for a pressure booster Pump, I am protecting a large Tank Farm on a Power Plant with Foam Monitors and I require about 10 Bar at the Monitor. By the time I work out the losses I need about 13 Bar at the inlet of the Foam Proportioning Skid (I am using a FireDos...
I have a client who has requested a connection from our Fire Main to top up a water cooled heater circuit, I have told him that it's just not done, Fire Mains are for Fire Systems and it will affect the operation of the Pumps but I can't find anything in NFPA 24 that tell me it is...
Can anyone please advise me if there is a restriction on the number of Fixed Fire Protection Systems (Deluge Waterspray)that can be supplied from a spur off a Yard Ring Main.
I thought there was something in NFPA 850 but I can't find it, my concern is the number of systems that may be isolated...
I have a client who is requesting a steam injection Fire Protection System to a storage silo.I think that what he actually means is a Deflegration Supression System. I have read NFPA 69 and I think I grasp the concept, however I have no experience in designing this type of system and I would...
I have a client who is utilising a secondary containment tank instead of a dike. The gap between the primary and secondary tank is around 750mm.
Can the containment tank be viewed as a method of exposure protection for the primary tank containing Distillate Fuel Oil? Thus negating the need for...
I am designing a Foam Enhanced Deluge System, I have to do a Hydraulic Calculation around the longest yard path of my Fire Main to ensure that I can satisfy the minimum nozzle pressure.
Is there a code requirement to do a Hydraulic Calculation on the most hydraulically favourable route (ie...
