Overview, Specification and Application of Nickel Alloy 400 Tubing

Alloy 400 is a nickel-copper alloy, commonly known as MONEL, resistant to seawater and steam at high temperatures and salt and caustic solutions. It is distinguished by strong general resistance to corrosion, good weldability, and moderate to high strength. In several uses, the alloy has been used. It has outstanding tolerance to brackish water or seawater rushing rapidly. When de-aerated, it is highly resistant to hydrochloric and hydrofluoric acids. At room temperature, the metal is mildly magnetic. In the pharmaceutical, oil, and marine sectors, Nickel Alloy 400 Tubing is commonly used.

In subzero temperatures, nickel alloy 400 has excellent mechanical properties that can be used at temperatures up to 1000 ° F, and has a melting point of 2370-2460 ° F. However, in the annealed state, Alloy 400 is poor in strength, so a range of temperatures should be used to improve the strength. This Nickel Alloy 400 Tubing performs excellently in seawater, with better tolerance than other copper-base alloys to cavitation corrosion. Up to 80 per cent concentration at room temperature and up to 15 per cent sulphuric acid at boiling temperatures are also used to treat sulphuric acid.

General Properties

A ductile nickel-copper alloy with resistance to a range of corrosive conditions is Alloy 400 (UNS N04400). In environments ranging from mildly oxidizing to neutral and under moderately decreasing conditions, the alloy is most commonly defined.

The alloy has a long history of use as a substance resistant to corrosion, going back to the early twentieth century when it was produced as an attempt to use nickel ore with high copper content. The ore content of nickel and copper was in the estimated proportion that is now officially defined for the alloy.

Nickel alloys specification

The most valuable materials to manufacture scientifically superior pipes and tubes for industrial uses are nickel alloys. For a wide variety of applications, their intrinsic properties make them viable. In high-temperature conditions, nickel alloys are highly corrosion resistant and can be used.

As nickel alloys are so ductile, they are machined to manufacture pipes and tubes easily while maintaining power. For example, this makes them ideal for heat exchangers in chemical manufacturing, which depends on tubing that can tolerate both the hot and corrosive environment. In steam engines, aircraft systems, and oil and gas exploration, Nickel Alloy 400 Tubing are also used.

There are quite a few types of nickel alloy pipes and tubes available on the market to satisfy the need for these high-quality products.

Pipes and tubes will also use the MONEL variety of nickel alloys. MONEL alloy 400 is a cost-effective alternative, but it can be hardened to provide a very tough result via hot or cold operation. It is on the market for decades and, because of its resistance to underwater corrosion, is a good option for marine applications.

Applications
· Marine and chemical processing equipment
· Process vessels and piping
· Marine fixtures and fasteners
· Gasoline and freshwater tanks
· Valves, pumps, propeller shafts

· Heat exchangers

Nickel alloy pipes and tubes of diverse thicknesses and dimensions come with a variety of specifications. Pipes and tubes are flexible items, and a design is typically required for any project to satisfy every requirement.
