Why flame failure cause in oil refinery heaters?
Flame failure in oil refinery heaters can occur due to several reasons, including insufficient fuel supply, malfunctioning burners, or improper air-fuel mixture. Additionally, equipment failures, such as faulty ignition systems or flame detectors, can contribute to the loss of flame. Environmental factors like high winds or changes in pressure can also impact combustion stability. Flame failure is critical to address promptly, as it can lead to unsafe operating conditions and potential explosions.
What is peritectic steel?
peritectic steels are ultra low carbon steels that fall into the phase change boundary, namely upper phase, that is it is directly influenced by alloying elements which can make this high tensile, high shrink steel difficult to cast for the automotive industry, great care has to be taken in mould powder choices, and also the cooling rate in terms of litres/Kilogramme. Using the Carbon equivalent to identify the peritectic chemistry is a bit hit and miss, hence the practicalities of making this product need much more study. It is problematic globally, indeed some producers cannot continuously cast this grade. Mould powder, secondary cooling and continuous unbending in the machine, all have to be optimised...expect disappointments!
What is free carbon in cast iron?
Free carbon in cast iron refers to carbon that exists in its elemental form within the iron matrix. It appears as graphite flakes or nodules, contributing to the material's unique properties, such as high fluidity during casting and improved machinability. This free carbon distinguishes cast iron from other metals.
Is LPG has high calorific value than methane?
Methane is CH4 and LPG(Butane) is C4H10. The energy in the Carbon Carbon bond (C-C)is more than that in the Carbon Hydrogen bond (C- H). Since there are more number of C-C bonds in butane (LPG) than in methane,calorific value of LPG or butane is higher than that of methane.
What is difference between MS rods and TMT bars?
TMT Bars - High strength deformed steel bars used for concrete reinforcement. The surface has many short ribs to allow the concrete to adhere better than if the bars had a smooth surface.MS Rods - Mild Steel rods are used to construct many things (such as scaffold construction), but are not the best choice for concrete. The surface of the rod is smooth, so it does not allow the concrete to adhere as well as if the surface had a texture.
Which type of flame is used for high carbon steel?
Most cutting and welding is done with a neutral flame.
What welding rods do you use for welding bennox plate?
bennox is a high carbon steel material so low hydrogen or carbon steel electrodes are recommended
Why high carbon high chromium steel cannot be weld?
High carbon high chromium steel is prone to cracking when welded due to its high hardenability and limited ductility at high temperatures. The heat-affected zone is more susceptible to cracking because of the rapid cooling after welding, leading to embrittlement. Preheating and post-weld heat treatments are often required to minimize the risk of cracking, but it can still be challenging to successfully weld this type of steel.
What is low carbon steel and high carbon steel?
Low carbon steel is steel with low carbon. High carbon steel is steel with high carbon
Distinguish between an oxidising flame and a carburising flame in oxy- acetylene welding?
Basically, you need to look at the flame itself, if the tip of the nozzle is bluish/white, and long , then the flame is a carburising or reducing flame, it contains a high ratio of acetylene compared to oxygen, and will produce a cooler sooty flame. this can be used to make metals more malleable when working them, but the carbon is not helpful, and cannot be used for welding operations An oxidising flame is more pupleish/white and is far hotter, with more oxygen than acetylene, this flame is used in cutting, but will harden steel, making it brittle. in between the two is the neutral flame where welding operations are carried out.

Why temperature drop is high in low carbon steel than high carbon steel?
Because high carbon steel has low fluidity & low carbon steel has high fluidity.
What is stronger low carbon steel or high carbon steel?
The amount of carbon in iron metal determines the strength and type of steel.Steel with low carbon is called low carbon steel and carbon with medium carbon called medium carbon steel. It is called low carbon steel if the carbon content is around 2.5 % or less. Others may be called medium or high carbon steel like that used in Die Steel of cutting tools. Generally low carbon steel are preferred if welding is adopted.
Can high carbon steel compact?
yes high carbon steel compacts
Which element is used in welding with oxygen?
Acetylene is commonly used in welding with oxygen to create a high-temperature flame for cutting and welding metal.
What is difference between 1018 steel and WCB?
AISI 1018 is usual quality structural grade A216 Gr WCB is Steel Castings, Carbon, Suitable for Fusion Welding, for High- Temperature Service
Is it possible to cold roll high carbon steel?
Yes you can bend high carbon steel.
