There are different types such as the Hastelloy B2 Slip On Flanges , socket weld flanges, and welded neck flanges. These have 790MPa minimum tensile strength, 355MPa minimum yield strength and 40% elongation rate.

The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments.Alloy C-276 is one of the most universally corrosion resistant alloys available today. It is used in a variety of environments ranging from moderately oxidizing to strong reducing conditions. Alloy C-276 has exceptional resistance to sulfuric acid, hydrochloric acid, formic acid, acetic acid, chlorides, solvents, wet chloride gas, hypochlorite and chlorine solutions.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications. Their inherent properties make them viable for a wide range of uses. Nickel alloys are exceptionally corrosion resistant and can be used in high-temperature environments.

It can be used in reducing chemical environments and chemical processing industry.

All of the common methods of welding can be used to weld Hastelloy C-276 alloy, although the oxyacetylene process is not recommended. Special precautions should be taken to avoid excessive heat input.

Hastelloy B3 fasteners are an excellent choice for bolting applications in chemical processing units because the alloy has excellent resistance to hydrochloric and sulfuric acids, while maintaining mechanical strength at elevated temperatures. HT PIPE offers all types of bolts, screws, studs, threaded rods, nuts, washers and custom bolts in Hastelloy B3.

These Hastelloy C276 contain a mixture of molybdenum, nickel and chromium species. Like other nickel alloys, it is ductile, easy to form and weld, and has excellent resistance to stress corrosion cracking (a form of easily degradable austenitic stainless steel) in chloride-containing solutions. Due to its high chromium and molybdenum content, it is resistant to oxidizing and non-oxidizing acids and exhibits excellent resistance to pitting and crevice corrosion in the presence of chlorides and other halides.
