What is Boiler Tubes?

Boiler Tubes are steels with open ends having a hollow section and are either made of carbon steel or alloy steel. The length of a boiler tube is greater than its periphery. Depending on the method of production, the boiler tubes can either be a seamless steel pipe or a welded steel pipe. These tubes are primarily found inside the boilers and it helps in heating water to produce steam. There are two main types of tube boilers namely fire-tube boilers and water-tube boilers. The boiler tubes are used in various industries including industrial processing plants, fossil fuel plants, electric power plants, etc.

What is the difference between an economizer and a superheater?
Superheater is an essential component of a boiler system. It helps to heat the steam above its saturation point so as to prevent it from getting condensed. It is also used in steam engines to improve the efficiency of the machine. It helps in electricity generation through steam turbines and is also used in steam engines. They are effectively used in processes such as steam reforming. An economizer, on the other hand, is a device present in boilers that helps in exchanging heat. It improves the efficiency of the system and also saves fuel. Using this, the temperature of boiler feedwater increases, and that lowers the needed energy input. It helps reduce the needed firing rates for rated boiler output.

Why use Stainless Steel Boiler Tube?
Stainless steel boiler tubes are one of the most efficient pieces of equipment that promises safe and long term operations. It helps to resist high temperatures and pressures, which is why it is abundantly used in steam pipelines, super heaters, etc. The features of the Stainless Steel Boiler Tubes have made it popular across various industries. It is resistant to corrosion and oxidation. It possesses high weldability and formability. The tubes also show excellent toughness even in cryogenic temperatures. It helps to eliminate the pressure stress on the wall of the uneven internal surfaces. It is also used to guide reaction exhaust gases created due to controlled combustion taking place in the engine.

Which is better stainless steel or carbon steel for Boilers?
Both stainless steel and carbon steel have some features that are unique to another. But comparing the two, it can be concluded that stainless steel is better than carbon steel for boilers. It is because stainless steel offers higher corrosion resistance than carbon steel. It is resistant to both high and low temperatures which is very crucial for boilers. The tubes made from stainless steel are quite durable and strong too. They come with low maintenance and can easily be cleaned. Stainless steel is known for its long lasting nature and can be given different finishes according to preferences. Even though carbon steel is cheaper compared to stainless steel, the features of SS are greater than it.
