Fire sprinklers have saved countless lives and millions of dollars worth of property. Perhaps we take them for granted. Have you ever stopped to wonder just how fire sprinklers work? The popular YouTube channel Discovery News explains.

Unlike what you see in the movies, setting off one fire sprinkler does not set off all of the sprinklers in a system. A sprinkler head installed by a fire protection sprinkler company goes off when subjected to intense heat. Each sprinkler head needs to feel that heat to go off.

This way, a sprinkler system does not destroy properly through water damage.

A sprinkler head contains a valve that’s connected to a water supply. This valve is covered by a glass tube. There is sugar alcohol inside of the tube that expands only when it feels a huge upsurge in heat. The gas breaks the glass, which releases the valve. Sprinkler heads are made to react with different degrees of heat.

Many fires start on the floor or on furniture, which is usually waist height. So, why are fire sprinklers installed on the ceiling? This is because heat rises. The heat from fires tends to rise quickly, setting off the fire sprinklers.

A diamond cluster is a ring that has numerous diamonds in it. This type of ring can take on various shapes. It can have a single band or two or three levels to it. Clusters are best when a person is trying to achieve an elegant look.

Another type of diamond ring that might interest someone is a three-stone diamond ring. This type of ring usually has the diamond in the center and two different types of stones on both sides of the diamond. They could be birthstones or something else. These are excellent for people who like to add a little uniqueness and flavor. An experienced jeweler can help a prospective buyer to choose the most suitable ring for a partner, fiance, or loved one.

Modern engine and gun parts have to be manufactured using high-tech modern processes in order to perform well under all conditions. Traditional manufacturing techniques might be able to shape metal and seal gaps between parts, but they can’t offer long-term protection from the elements or create non-stick surfaces.

In order to achieve these and other goals, some gun and engine parts manufacturers offer plasma coating services. Unlike traditional coatings that have to be weak and malleable enough to be applied under normal conditions, plasma coatings are much tougher.

In order to apply a plasma coating, the coating material is heated in plasma. Then it is applied to the object that needs to be coated. Generally, that object is metal or ceramic because it needs to be able to withstand high temperatures during the coating process. Once the coating hits the surface of the object, it is almost immediately permanently bonded in place.

To see a plasma coating service in action, take a look at the video posted here. It shows plasma coatings being applied in normal atmosphere and vacuum conditions. It works on both large parts for engines and small parts for more delicate devices like guns.
