How does Alloy 20 Seamless Tube differ from other stainless steel tubes?

Alloy 20 Seamless Tube sets itself apart from other stainless steel tubes through its unique composition and specific properties. While traditional stainless steel tubes, such as the commonly used 304 and 316 grades, offer good corrosion resistance, Alloy 20 Seamless Tube takes it further. It exhibits superior resistance to various corrosive agents, including sulfuric acid, nitric acid, and chloride solutions.

This enhanced corrosion resistance makes Alloy 20 Seamless Tube well-suited for aggressive environments where other stainless steel tubes may not perform as effectively. Additionally, Alloy 20 Seamless Tube contains higher levels of nickel, chromium, and molybdenum, along with the addition of copper, contributing to its exceptional resistance to pitting and crevice corrosion. Furthermore, Alloy 20 Seamless Tube maintains its excellent mechanical properties, such as strength and flexibility, even in corrosive conditions, ensuring its reliability and longevity in demanding applications.

What are the common applications of Alloy 20 Seamless Tube in various industries?

Alloy 20 Seamless Tube finds wide-ranging applications across various industries. Its exceptional corrosion resistance and mechanical properties make it an ideal choice for chemical processing, pharmaceutical, food processing, and oil refining industries. Alloy 20 Seamless Tube is commonly used in chemical processing to produce acids, solvents, and speciality chemicals. In the pharmaceutical industry, it is used in drug manufacturing, storage, and transportation equipment. Alloy 20 Seamless Tube produces corrosive-resistant equipment for handling acidic or high-temperature food products in the food processing sector.

Alloy 20 Seamless Tube Manufacturing Process

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. Alloy 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.
