Foreign Fire Sprinklers

A Guest Post Submitted By Mike W

Have you ever wondered about the use of fire sprinklers outside the U.S.? There are actually many countries that use and manufacture sprinkler heads. The use of sprinklers now spans the entire globe. Sprinklers can be found on every continent with Antarctica being a possible exception. However, sprinklers are not manufactured on every continent.

I have been collecting sprinkler heads for a little over six years, but I have recently gained a special interest in sprinklers from other countries. In January of 2009, I purchased my first foreign-made sprinkler heads. My first foreign heads were from England and Denmark. While Denmark is host to one manufacturer, “GW”, England is home to the most sprinkler companies outside of the U.S. These brands include: Mather & Platt (Grinnell), Atlas, Matthew Hall, Spraysafe, Wormald (British sector), Titan, Firekil, and Angus.

Sprinkler Protection from Corrosion

In the beginning there was brass and it was good. Brass while a good metal for use in water, is was not suitable for corrosive atmospheres found in some industrial facilities.

I live near the coast in Florida and have seen many sprinklers installed in areas such as parking garages, apartment breeze ways, etc. All a nice shade of green. My company makes good money replacing heads in places such as this. Early on in the sprinkler industry they discovered this and worked to develop finishes and coating to protect against corrosion.

What is the best material used to extinguish fires?

What is the best material available to man to use in fire protection systems? Oxidane, Hydrogen oxide, Dihydrogen monoxide, Hydrogen Hydroxide, Hydroxylic acid, Hydroxic acid H2O or just plain old WATER? Actually all the items listed are just water!

We are in the business of putting water on fires. Either as a fire sprinkler contractor or fire fighter. We both employ specialized equipment whose only purpose is to get water on the fire in many different ways.

What makes water such a great fire fighting medium? Both as liquid water and as vaporized steam, water has properties that make it good for firefighting. Water has a high capacity for holding heat. Thus when applied to a fire, water carries the heat away and reduces the fuel’s temperature. When water absorbs enough heat it turns to steam which is effective in displacing oxygen and starving the fire.

Class vs Pounds The Rating of fittings

What is the pressure rating of a Class 125 fitting? What is the pressure rating of a Class 250 fitting? The answer to both of those questions is the same. It depends!

One thing that’s been a problem over the years in dealing with fittings is the nomenclature used. For years we called our cast iron fittings 175 pound fittings. And then when we needed higher pressures we called for 300 pound fittings. I’ve had plenty of discussions with engineers over what fittings to use due to a general misunderstanding of how fittings are rated. I learned to start by trying to educate people about this subject.
