The outstanding oxidation resistance of HASTELLOY X pipe bend is illustrated below. Tests were conducted by exposing samples to dry air at 2000 Deg. F. and to dry air pressurized to 300 psi at 1750 Deg. F.

It is well known that Hastelloy c22/C276 fasteners have good dimensional accuracy, corrosion resistance, durability, high durability, high flexibility, strong structure, high tensile strength and other characteristics. In addition, fasteners are resistant to wear in high temperature atmospheres and corrosive environments. Some of the environments in which these fasteners exhibit resistance are oxidizing media, reducing media, chloride environments, and sulfur environments. They are resistant to attack by chemicals such as nitric acid, chlorine, sulfur, acetic acid, organic, inorganic, phosphorus, etc.

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 B2 is a nickel-molybdenum alloy with significant resistance to reducing environments such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 is resistant to pure sulfuric acid and many non-oxidizing acids. This alloy should not be used in the presence of oxidative contaminants in oxidizing or reducing media. Premature failure may occur if Alloy B2 is used in the presence of iron or copper in systems containing hydrochloric acid.

These Hastelloy Alloy C276 Forgings is used for dissimilar welding applications including other nickel ¨C chromium ¨C molybdenum alloys and stainless steels, and for weld overlay or cladding of steels. The alloy is used in flue gas desulfurization systems. It has excellent resistance to pitting and stress corrosion cracking, and resists wet chlorine gas, hypochlorite and chlorine dioxide. The alloy is also resistant to seawater and brine solutions.

Cold bending methods often rely on sheer physical force to help bring the pipe to its final shape while hot bending methods use careful heating to reduce the force required.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

Hastelloy B3 pipe has good resistance to stress corrosion cracking that is chloride induced. The good resistance to a wider range of organic acids makes Hastelloy B2 pipes a popular product.

The high molybdenum content imparts resistance to localized corrosion such as pitting.

Hastelloy C-276 bushings are also used in sour gas wells, pulp and paper production, waste disposal, pharmaceutical and food processing equipment. Other important properties of this alloy Nickel Alloy C-276 and Hastelloy C-276 include its resistance to oxidizing agents.

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.
