Hi

Anyone help me about sprinkler system.

How can i decided the explosion temperature of the sprinkler ( using for building)?

Sprinkler Temperature



Temperature:

The nominal operating temperature of the automatic chuveros are listed below as peqena made a table for you to understand better.
The chuveros resistant to corrosion can be identified in three ways: as a point at the top of the baffle, with specific colors and coatings for the color of the arms.


Temperature range, color classification of sprinklers

[link Point to another website Only the registered members can access]


1 Special coatings
Showers resistant to corrosion shall be installed in places where there is the presence of corrosive vapors, moisture or
other environmental conditions that can cause damage.
The anti-corrosive coatings should be applied exclusively by the manufacturers of showers.
Unless specified by the manufacturer, the shower should not be painted, coated and any shower can only be
replaced by another of the same features, including hole diameter, temperature of operation and
water distribution.
Any decorative finish of the shower should be performed by the manufacturer.


2 Canoplas and wrappers
Canoplas and non-metallic enclosures must be provided by the manufacturers of the shower.
Canoplas and enclosures used with sprinklers embedded or non-apparent must be provided in conjunction
with showers.

3 Guards
The automatic sprinklers installed in places subject to mechanical damage should be provided with guards.

4 Stock of spare showers
Showers should be kept spare for immediate replacement in case of operation or damage. These showers
must have the same characteristics that are installed and should be kept in place whose
the temperature does not exceed 38oC.
A special key for removal and installation of the showers should be available next to them.
The stock of spare showers should include all the templates installed, shall be as follows
way:

a) 6 showers, at least for systems with up to 300 showers;
b) 12 showers, at least for systems with showers 300-1000;
c) 24 showers at least for systems with more than 1000 showers.


I hope this helps.

I found some datas in NFPA 13. Like that 38 C, 66 C and different colour etc. But these temperature is called that ceiling temperature. What does ceiling temperature mean? Is ceiling temperature max. resistance of sprinkler ? Above this temperature sprinkler open. Right?

In my project, max. local temperature 55 C. So can I specified ceiling temperature 66 C ?

Tebela in annex in my previous postagem is identical, the table 3-2.5.1 (Temperature Ratings, Classifications, and Color Codings) 13 NFPA Edition 1999.

Now We go its Questions.


1º: What It means Temperature of Ceiling or also known as Maximum limit of temperature?

Resp: It is the Ambient temperature


2º: What It means Value of Temperature?

Resp: It is the Limit of Temperature in which the weld that keeps the plate of canopla melts, with this the plate of canopla plain is set free thus displaying internal sprinkler to the increase of the ambient temperature.


3º: In my Project the ambient temperature is 55°C. Can thus I specify the temperature of ceiling 66°C?

Resp: To read the Item Carefully: 5-3.1.4 (Temperature ratings) 13 NFPA Ed.1999.


In Annex a Drawing to assist in case of some doubts.

Are you looking for a specific book?

Here are references on mitigation of Hydrogen Sulfide...

Thanks for great help.
I'm evulating the charge feed for Sulfur Recovery unit.
If the large amout of H2S vapor release from the feed vessel.
Owing to the concerntration of H2S is near pure.
We prefer to install a set of water spray for mitigation the concerntration of H2S vapor. For emergency response use.
Is there any reference for such design and emergency response guide?
