What is Hastelloy C22, and why is it used for boiler tubes?
Hastelloy C22 is a high-performance nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance in various aggressive environments. It is specifically designed to withstand the corrosive effects of acids, chlorides, and other harsh chemicals, making it an ideal choice for various industrial applications. In the context of boiler tubes, Hastelloy C22 offers several advantages. Its superior corrosion resistance helps protect the tubes from the corrosive elements in boiler feedwater and flue gases, which can lead to the degradation and failure of conventional materials. Hastelloy C22 exhibits excellent mechanical properties, including high tensile strength and pitting and crevice corrosion resistance. These characteristics make it a reliable and durable choice for boiler tubes, ensuring prolonged service life and enhanced operational safety in demanding environments.

How does the corrosion resistance of Hastelloy C22 compare to other materials commonly used for boiler tubes?
When it comes to comparing the corrosion resistance of Hastelloy C22 with other materials commonly used for boiler tubes, it stands out as an exceptional choice. Hastelloy C22 offers superior corrosion resistance in highly aggressive environments, particularly against various acids, chlorides, and oxidizing agents. That sets it apart from other materials commonly used for boiler tubes, such as carbon steel, stainless steel, and even nickel-based alloys.
While carbon steel and stainless steel may be suitable for less corrosive environments, they can be susceptible to various forms of corrosion in the presence of acids or chlorides. In contrast, Hastelloy C22 demonstrates excellent resistance to localized corrosion phenomena, such as pitting and crevice corrosion, which are major concerns in boiler tube applications. Additionally, Hastelloy C22 maintains its integrity and performance even at elevated temperatures, further solidifying its position as a highly corrosion-resistant material for boiler tubes.

Welding Process
The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a Tube.
Drawing/ Floating Process
Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless Steel Tubes benefit from maintaining the integrity of their surface.
Continuous Seamless Tube Mills
The production of seamless tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, seamless pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.
Continuous Casting
A notable advancement in the production of seamless Tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the Tubes.
Annealing
Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.
Sinking Process
Tube sinking is a drawing technique that reduces the diameter of Tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, Tube sinking is ideal.
Inspection and Testing
Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
