Hastelloy Tube

Hastelloy Tube Manufacturer, Supplier in India

Hastelloy Tube is a type of tubing made from a family of nickel-based alloys known as Hastelloy. These alloys are designed to offer exceptional resistance to a wide range of corrosive environments, making them highly suitable for various industrial applications. One of the key characteristics of Hastelloy tubes is their exceptional resistance to corrosion, including resistance to both uniform and localized corrosion. They exhibit excellent performance in highly corrosive media such as acids, salts, oxidizing agents, and reducing environments.

Hastelloy tubes also possess high strength and good mechanical properties, allowing them to withstand challenging conditions such as high temperatures and pressures. Additionally, they offer excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, further enhancing their durability and reliability. These unique characteristics make Hastelloy Tubes an ideal choice for industries such as chemical processing, oil and gas, pharmaceuticals, aerospace, and many others where corrosion resistance is paramount.

How does Hastelloy tube differ from other types of tubing materials?

Hastelloy Tubes differ from other tubing materials primarily due to their unique composition and exceptional corrosion resistance properties. While many other tubing materials may offer decent corrosion resistance, Hastelloy alloys provide superior resistance to corrosive environments, including highly aggressive acids, alkaline solutions, and harsh chemicals. Compared to stainless steel, commonly used for tubing applications, Hastelloy tubes exhibit higher resistance to localized corrosion, stress corrosion cracking, and pitting.

Additionally, Hastelloy alloys can maintain their structural integrity and mechanical properties even in extreme temperatures, making them suitable for high-temperature applications where other materials may degrade or fail. Another distinguishing factor is their excellent resistance to oxidation, which enables them to withstand the effects of oxidizing agents and retain their performance over time. The exceptional corrosion resistance, high strength, and temperature stability of Hastelloy tubes make them a preferred choice in industries where protection against corrosion and durability are critical factors.

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. Hastelloy 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.
