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.

These flanges are usually welded or screwed. In those instances where welding or bolting the flange is not possible, many industries prefer using WNR 2.4602 Threaded Flanges.

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.

Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions (a form of degradation to which the austenitic stainless steels are prone).

Hastelloy is a term used to describe nickel metal that has been alloyed to increase corrosion resistance. This is primarily done through the addition of molybdenum and chromium.It is commonly used for pipes and valves in the chemical and petrochemical industries. It is also used in reactor vessels in the chemical and nuclear industries.

Hastelloy B2 pipe bend resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition.

Our Hastelloy B2 Ring Joint Type Flanges is not recommended for use in the presence of ferric or cupric salts as these salts may cause rapid corrosion failure. Ferric or cupric salts of these Hastelloy B2 Nippo Flanges may perhaps develop when hydrochloric acid comes in contact with iron or copper.

HASTELLOY(r) C276 can be formed by cold working using conventional techniques.
