Hastelloy c276 tube

UNS 0276 heat exchanger tube and Hastelloy C276 seamless tube suppliers in UAE

Difference between welded redrawn and Hastelloy C276 seamless tube

Hastelloy C276 can get manufactured through various techniques. A welded tube uses strips or sheets that undergo welding longitudinally. This tubing has a seam and is a cost-effective approach. But Hastelloy C276 tubing for chemical processing and tackling corrosion often gets welded and redrawn.
Such components get redrawn after the standard welding to attain a homogenous finish. The redrawing boosts its performance by improving fatigue life and mechanical properties.
In contrast, a Hastelloy C276 seamless tube does not have any welds. It usually gets produced via extrusion. The material gets forced through a die and heat-treated in a furnace. Moreover, seamless tubing offers improved corrosion resistance and can operate in high temperatures and pressures.

How is the annealing of alloy C276 tube done?

Hastelloy C276 can undergo annealing as a heat treatment for softening. A nickel alloy C276 bright annealed tube has better fabricability, making it a better fit for versatile applications.
This procedure involves heating the material to a critical temperature to induce recrystallization. Then, the C276 tubing gets slowly cooled to room temperature. Annealing can improve the chemical properties of the alloy.
The standard annealing process for Hastelloy C-276 involves a temperature of 1170°C to 1200°C. You have to hold it for 10 hours to remove any segregation. Hastelloy C276 tube suppliers can perform the procedure based on your desired requirements.

Is Hastelloy C276 tubing suitable for nuclear power stations?

Nuclear power stations require tubing that can operate in extreme temperatures and pressures. Hastelloy C276 displays strength and stability in severe conditions. Also, this material exhibits efficient heat transfer. A DIN 2.4819 redrawn tube can also tolerate attacks by harsh agents like acids, chlorides, and molten fluoride salts. These properties make it desirable for use in steam generator tubing for nuclear power industries.
This tubing mainly gets used in pipes, heat exchangers, steam lines, exhaust ducts, and valves. A weld overlay with Hastelloy C276 can be effective mitigation for corrosion. A UNS N10276 cold drawn tube is the preferred material in many nuclear fuel plants and reactors.
