What is Inconel 718, and why is it commonly used for boiler tubes?

Inconel 718 is a nickel-based superalloy widely recognized for its exceptional high-temperature strength, corrosion resistance, and mechanical properties. It is composed primarily of nickel, chromium, and iron, with small amounts of other elements such as molybdenum, niobium, and titanium. This alloy is commonly used for boiler tubes due to its unique properties, making it suitable for demanding boiler applications. The high-temperature strength of Inconel 718 allows it to withstand extreme operating conditions and resist deformation under thermal stress. Its excellent corrosion resistance also ensures long-term durability and protection against the harsh environments encountered in boilers. These characteristics and good weldability and fabricability make Inconel 718 a preferred material choice for boiler tubes in various industrial sectors, including power generation, chemical processing, and oil refining.

What are the key properties of Inconel 718 make it suitable for boiler tube applications?

Inconel 718 possesses several key properties that make it highly suitable for boiler tube applications. Its exceptional high-temperature strength enables it to withstand the demanding operating conditions and thermal stresses experienced in boilers. This property allows Inconel 718 to maintain its structural integrity and resist deformation even at elevated temperatures, ensuring reliable performance over extended periods.

Inconel 718 exhibits excellent corrosion resistance, particularly in aggressive environments involving chemicals, acids, and high-temperature gases. This resistance to corrosion helps protect the boiler tubes from degradation, prolonging their lifespan and reducing maintenance requirements.

Moreover, Inconel 718 demonstrates good mechanical properties, including high yield and tensile strength, contributing to its overall durability and resistance to mechanical stress. That enables the tubes to withstand pressure differentials and mechanical loads during boiler operation.

Inconel 718 exhibits favorable fatigue and creep resistance, allowing it to withstand cyclic loading and prolonged exposure to high temperatures without experiencing significant degradation in performance. This property is crucial in boiler applications where cyclic thermal stresses and long-term exposure to high temperatures are common.

Inconel 718 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.
