Can stainless steel 304H seamless tubes withstand high temperatures and corrosion?

Stainless steel 304H seamless tubes are specifically designed to withstand high temperatures and offer exceptional resistance to corrosion. These tubes exhibit excellent heat resistance properties, allowing them to maintain structural integrity even when exposed to elevated temperatures. That makes them ideal for heat transfer applications, such as heat exchangers and boilers. Moreover, stainless steel 304H seamless tubes demonstrate remarkable corrosion resistance, making them suitable for corrosive environments.

They are highly resistant to general corrosion, including pitting and crevice corrosion, as well as to a wide range of chemicals, acids, and alkalis. This corrosion resistance ensures the longevity and reliability of the tubes, making them a preferred choice in industries where corrosion is a major concern, such as chemical processing, oil and gas, and marine applications. Stainless steel 304H seamless tubes offer a robust combination of high-temperature and corrosion resistance, making them well-suited for demanding environments where both factors are critical.

Stainless Steel 304H 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. 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.
