Hastelloy Cold Drawn Tubes and Tubes – Offers good machinability, higher strength and constant degrees of freedom compared to hot rolled and cold drawn tubes. These pipes work more efficiently because their microstructure is very constant and also have increased physical properties.

INCONEL alloy C-276 is designated as UNS N10276 and Werkstoff Nr. 2.4819. It is listed in NACE MR0175 for oil and gas service.

Hastelloy C2000 fasteners combine the excellent resistance to oxidizing media of C276 with excellent resistance to non-oxidizing environments, making it a unique alloy for protecting chemical process equipment under a variety of conditions, including fluids contaminated with iron ions . It is designed to provide greater versatility than other Hastelloy alloys. This is achieved by increasing the content of chromium and molybdenum and adding a small but effective amount of copper (1.6%). The addition of copper increases the temperature capability of C2000 fasteners in sulfuric, hydrofluoric, and dilute hydrochloric acids.

C22 can be hot worked or cold worked. However, C22 work-hardens rapidly. Therefore, cold working must often be performed in stages with intervening anneals. Parts should be annealed after cold working.

Built-up sections are produced at the factory and is then transported to the original site and assembled. This concept is generally used to build Metro stations, industrial units, warehouses, etc.

ANSI B16.11 Hastelloy B2 plugs have excellent resistance to oxidizing aqueous media including wet chlorine and mixtures including oxidizing or nitric acid.

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.

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid.

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.

These Hastelloy B2 Weld Neck Flanges should not be used in oxidizing media or where oxidizing contaminants are available in reducing media.

It is used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of ¡°sour¡± natural gas.

The flanges also have 8.89 grams per cubic centimeter density and 1370 degrees melting point. The DIN 2.4617 Socket Weld Flanges and other flanges are used in high temperature, high corrosive and high stress applications due to the higher mechanical properties.

Controlling other alloying elements such as iron and chromium

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.

Hastealloy is a term that refers to a group of corrosion resistant metal mixtures that are based on nickel. Hastealloys have a unique combination of properties that provide them with significantly stronger corrosion resistance capabilities compared to traditional alloys. As such, it was widely accepted in the chemical process and associated industries, and now has a 50-year-old track record of proven performance in a vast number of corrosive chemicals.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications.Nickel Pipe is a metal pipe that is made up of an alloy that has primarily nickel and other elements in its composition.

Hastelloy B2 Round Pipes (UNS N10665) is used for most chemical process applications in the welded condition, gasoline refining.

Alloy B Its popularity has been hindered by its availability. All of these materials are good against reducing acids, but very hard against oxidizing acids. Due to the high molybdenum content, this alloy is relatively expensive than other alloys. At the same time, it has excellent corrosion resistance to medium-concentrated sulfuric acid and various non-oxidizing acids, good resistance to chloride stress corrosion cracking (SCC), and good resistance to various organic acids.

This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such ¡°upset¡± conditions occur frequently.

Hastelloy C-4 is a nickel-chromium-molybdenum alloy with outstanding high temperature stability. It has high ductility and corrosion resistance. It’s high temperature resistance up to 1900 ¡ãF (1038 ¡ãC) makes it suitable for most chemical process application in the “as” welded condition.
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). With its high chromium and molybdenum
contents, it is able to withstand both oxidizing and non-oxidizing acids, and is resistant to
pitting and crevice attack in the presence of chlorides and other halides.

Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used.

Hastelloy B3 fasteners offer the same excellent resistance to hydrochloric acid and other strong reducing chemicals as other B alloys, including B2, but with significantly enhanced thermal stability and easier fabrication. In addition, B3 fasteners are highly resistant to attack from cut lines and heat affected zones. Like B2 alloys, B3 fasteners are not recommended for use in the presence of iron or copper salts that can cause rapid corrosion failure.
