Hastelloy C276 bushings have excellent resistance to strong oxidizing salt solutions such as ferric chloride and cupric chloride. Alloy C-276 has excellent phosphoric acid resistance at all temperatures below boiling point and concentrations below 65%.

Nickel- and cobalt-based corrosion-, temperature- and wear-resistant alloys, such as Hastelloy B2, are classified as moderate to difficult when machined, but it should be emphasized that these alloys can be produced at satisfactory speeds using conventional production methods processing. During machining, these alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface, and provide high resistance to metal removal due to their high shear strength.

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

The thermal stability of Hastelloy B3 pipes is superior.

Hastelloy X alloy is a nickel-chromium-iron-molybdenum alloy with excellent oxidation resistance and high temperature strength, while still being easy to manufacture.

According to the flange size, wall thickness and diameters, the pressure classes vary from class 150 through class 2500. There are also different faced flanges such as the ring type joint Alloy B2 RTJ Flange, raised face flange and flat face flange.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

The corrosion resistance property of the alloy is credited to the addition of both Molybdenum and nickel.

It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.

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.
