Utility Piping | Steam Piping - Steam Heating

In Previous Article We seen the different use and types of steam.

We know the dry saturated steam is generally used in pipe heating process.

Steam is one of the most common and effective heat transfer mediums used in industry, but it is not the only medium available. Other fluids such as hot water and oil are also used for indirect heating in heat exchangers.

So following are the advantages of steam heating:

In case of heating with hot water it only loose sensible heat around 17kcal/hr But if we use dry saturated steam then it loose latent heat around 539kcal/hr.

So we can see the use of the steam is more preferable in case of pipe heating.

What Is Steam

In  a simple word Steam is the gas formed when water passes from the liquid to the gaseous state.

The process of formation of steam can be explained as,

In liquid water, H2O molecules are constantly being joined together and separated. As the water molecules are heated, however, the bonds connecting the molecules start breaking more rapidly than they can form. Eventually, when enough heat is supplied, some molecules will break free. These 'free' molecules form the transparent gas we know as steam, or more specifically dry steam.

So there are main two form of the steam: Dry steam and wet steam 

Steam is Called Dry steam when all its water molecules remain in the gaseous state. It's a transparent gas.

And is called as Wet Steam When Is Contain water particles in it. 

Because there are various form of the steam so according to the phase of steam use is different.
