What material use for boiler tubes?
Boiler tubes are typically made from high-strength materials such as carbon steel, alloy steel, and stainless steel. Carbon steel is commonly used for lower pressure applications, while alloy steels, which may contain chromium or molybdenum, are preferred for higher temperature and pressure environments due to their enhanced durability and resistance to corrosion. Stainless steel is also used in specific applications where corrosion resistance is critical. The choice of material depends on factors like operating conditions, pressure, and the type of fluid being heated.
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!
Do you need to be a certified welder to weld ammonia pipe in Michigan?
In Michigan, there is no specific state certification required solely for welding ammonia pipes. However, welders must adhere to relevant industry standards and codes, such as those set by the American Society of Mechanical Engineers (ASME) or the American Welding Society (AWS). It's also crucial for welders to have the appropriate qualifications and training for the specific type of welding being performed, especially in high-pressure applications. Employers may require certifications to ensure safety and compliance with regulations.
What is grade of steel in LPG portable cylinders?
The grade of steel commonly used in LPG portable cylinders is typically high-strength low-alloy steel, often classified as S235 or S355 according to European standards. These grades provide the necessary strength and ductility to withstand the pressures associated with liquefied petroleum gas. Additionally, the steel is usually treated with protective coatings to prevent corrosion and ensure safety during storage and transportation.
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.
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.
Can high carbon steel compact?
yes high carbon steel compacts
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 carbon steel and high tensile steel the same?
No, carbon steel and high tensile steel are not the same. Carbon steel is a type of steel where the primary alloying element is carbon, and it can have varying carbon content, affecting its hardness and strength. High tensile steel, on the other hand, is specifically designed to have high strength and tensile properties, often achieved through alloying elements like manganese, nickel, or chromium, and specific heat treatments. While high tensile steel can be a type of carbon steel, not all carbon steels are classified as high tensile steel.
Is it possible to cold roll high carbon steel?
Yes you can bend high carbon steel.
