What are Incoloy 800 Flanges?
Incoloy 800 (UNS N08800 / W.Nr. 1.4876) is an iron-chromium-nickel alloy engineered for high tensile strength and outstanding resistance to elevated temperatures. The high nickel content provides exceptional protection against chloride pitting and stress corrosion cracking (SCC), making it an ideal choice for high-stress industrial applications.
For more severe environmental demands, improved versions such as Incoloy 800H (UNS N08810) and Incoloy 800HT (UNS N08811) offer enhanced creep rupture and stress rupture strengths. Whether for critical high-temperature thermal processing units or standard fluid transfer piping, Sankalp Alloys Overseas is your go-to solution provider for premium Inconel N08800 Flanges.
Types of Incoloy 800 Flanges We Supply
We manufacture and export a wide spectrum of ASTM B564 Incoloy 800 Forged Flanges to meet custom process requirements:
- Inconel N08800 Slip On Flanges: Easy to align and slide over the pipe, widely used for moderate pressure systems.
- Incoloy 800 Weld Neck Flanges: Designed to transfer stress to the pipe, offering excellent structural reinforcement in high-pressure setups.
- ANSI B16.47 Incoloy 800 Blind Flanges: Used to block/seal the end of piping systems or pressure vessel openings securely.
- Inconel N08800 Socket Weld Flanges: Ideal for small-diameter, high-pressure piping applications.
- Incoloy 800 Lap Joint Flanges: Preferred in systems requiring frequent dismantling for inspection and cleaning.
- Incoloy 800 Threaded Flanges: Screwed onto pipes without welding, ideal for low-pressure gas or fluid pipelines.
