What is Alloy 20, and why is it used in boiler tubes?

Alloy 20 is a specialized nickel-chromium-molybdenum stainless steel alloy commonly used in boiler tubes. It is renowned for its exceptional corrosion resistance, especially in highly corrosive environments containing sulfuric acid, phosphoric acid, and chloride solutions. The alloy's composition provides excellent mechanical properties, such as high tensile strength and good impact toughness, which are crucial for withstanding the stresses and pressures experienced in boiler operations. Additionally, Alloy 20 exhibits superior resistance to pitting, crevice corrosion, and stress corrosion cracking, making it an ideal choice for boiler tubes in industries with corrosive elements. This alloy's exceptional performance and durability help ensure the integrity and longevity of boiler systems, contributing to their efficiency and safety.

Alloy 20 Boiler Tube Manufacturing Process

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.
