Modern processing systems are often a complex network of turns, elevation changes, fittings, and more.

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 C22 alloy includes nickel, chromium, molybdenum, and tungsten, which result in extreme resistance to pitting and stress corrosion cracking.

Hastelloy C-276 also has excellent resistance to pitting corrosion, stress corrosion cracking and oxidizing atmospheres, as well as excellent resistance to many different chemical environments.

Alloy B2 (UNS N10665 / W.Nr. 2.4617) is a solid solution strengthened, nickel-molybdenum alloy, typically used in extreme reducing conditions.

c276 is highly resistant to most chemicals and corrosive environments. The anti-corrosion and anti-oxidative properties come from the composition of chromium and molybdenum.

Alloy C276 Seamless Nickel Tube is a nickel molybdenum chromium alloy with added tungsten for excellent corrosion resistance in a wide range of harsh environments. The high molybdenum content makes this alloy particularly resistant to pitting and crevice corrosion.

Like many other nickel alloys, it is ductile and easy to form and weld. This alloy is used in most industrial environments where corrosive chemical environments exist and other alloys fail.

Hastelloy C2000 lap joint flanges are used for heat treatment applications. They have very little carbon content and high nickel content, which makes them much stronger than any other flanges.

Alloy C-276 has excellent resistance to pitting corrosion, stress corrosion cracking and oxidizing atmospheres up to 1900¡ãF.

Strong and Oxidation Resistant to 2200 Deg. F (1200 Deg. C) – HASTELLOY X pipe bend is a solid solution strengthened grade has good strength and oxidation resistance up to 2200 Deg. F (1200 Deg. C).

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 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.

C-22 is a great alternative when superaustenitic stainless steels (AL-6XN, 904L, and 254 SMO) and duplex stainless steels (2205 and 2507) will not withstand extremely aggressive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy with better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy, like Hastelloy C-276, C-4, and alloy 625.

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.

Exposures like this are regularly experienced during heat treatments that are linked with fabrication.

This alloy of flanges ensures excellent formability and weldability. Therefore these are cold and hot worked.
