Process piping systems rarely travel in a straight line from process to process.

Alloy C276 Forged Flange Hastelloy C276 Flanges are made up of the nickel chromium molybdenum alloy that is called hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in it. The Hastelloy C276 Flanges have high melting point of 1370 degrees Celsius. This high melting point allows for higher operating temperatures of the flanges. The material also has 790MPa minimum tensile strength and 355MPa minimum yield strength.

Hastelloy C-276 alloy excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, and hot contaminated media (organic and inorganic).

The flange is second most used joining method after welding. Flanges are used when joints need dismantling. It provides flexbility for maintenance. Flange connects the pipe with various equiment and valves. Breakup flanges are adde din the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls ae required in the selection and application of all these elements to attain a joint, which has acceotable leak tightness.

NAS NW276 is a Ni Cr Mo alloy with excellent corrosion resistance in both oxidizing and reducing atmospheres. In this alloy, carbide precipitation in the heat affected zone (HAZ) is suppressed and corrosion resistance is improved by reducing the contents of C and Si.

Alloy B (UNS N10001) was developed to resist hydrochloric acid. Hastelloy B2 has replaced it. Alloy B3 (UNS N10675) is a newer variant with higher thermal stability.
