Incoloy Pipe Fittings

Incoloy pipe fittings

What are Incoloy Pipe Fittings?

A worthy selection for industries exposed to corrosive environments is Incoloy, a sturdy material containing nickel, iron, and chromium. Incoloy pipe fittings also have molybdenum, titanium, and copper, while maintaining a total nickel content of less than 50 percent. It is a prime differentiator from Inconel, whose nickel percentage is much higher.

Alloy 825 fittings, a popular grade of this material, withstands oxidizing and reducing environments. Manufacturers can produce fittings to address varied piping requirements, for example, tees, a DIN 2.4858 reducer, elbows, etc. Their performance in aqueous media is fabulous.

What are the key properties and advantages of Incoloy Pipe Fittings?

The outstanding corrosion resistance of Incoloy alloy 825 buttweld fittings is well-documented. They can tolerate sulfuric and phosphoric acids, even operating in phosphoric acid evaporators, and resist stress-corrosion cracking. Besides this, here are other noteworthy benefits:

  • Can handle temperatures up to 1000°F: an incoloy 800 elbow can operate in pressure vessels up to 800°F.
  • Shows resistance to pitting (development of cavities) and crevice corrosion
  • An Incoloy 800H stub end is easy to fabricate and work with

We recommend acquiring fittings from trusted vendors that follow tight tolerances and steep quality standards. an incoloy elbow can deliver long service duration when produced from premium raw materials and thoroughly tested for performance
