The Corrosion Resistant HASTELLOY alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries.

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.

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.

Each of them have structural differences. These flanges are made up of a nickel, chromium, molybdenum alloy that has 50% nickel 14% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in the composition.

Hastelloy B2 fasteners are primarily used for excellent resistance to reducing environments such as hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid. Like other Hastelloys, B2 fasteners can be used in the as-welded condition because they resist the formation of grain boundary carbide deposits in the weld heat-affected zone. Due to reduced ductility, B2 fasteners are not recommended for use between 1000¡ãF and 1600¡ãF.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available.

HASTELLOY C-2000 alloy is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes. Typical chemical process industry (CPI) applications include reactors and heat exchangers.

The flange is second most used joining method after welding. Flanges are used when joints need dismantling. It provides flexbility for maintenance. Flange connects the pipe with various equiment and valves. Breakup flanges are adde din the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls ae required in the selection and application of all these elements to attain a joint, which has acceotable leak tightness.

Rotary draw bending can also utilize mandrels.

This nickel steel alloy can be used in the as-welded condition because it resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone.

Hastelloy C-276 is easily fabricated by welding, using methods similar to those used for nickel-based alloys.

Hastelloy B2 pipe bend provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media.

The Hastelloy UNS N10665 Pipe Flanges come under the ANSI, ASTM, DIN and other international standards with various dimensions and pressure classes.

Hastelloy can be used with all common welding methods, but oxyacetylene and submerged arc processes are not recommended when the manufactured product is intended for corrosion service.

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 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. These alloy B2 bolts are a wrought nickel molybdenum alloy that can be used in the as-welded condition. It is highly resistant to hydrochloric acid of all concentrations and temperatures. Known as UNS N10665 bolts, these bolts are also resistant to stress corrosion cracking and pitting.

Hastelloy B2 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. The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.Steel pipes can be disintegrated on the basis of its application.Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line, agriculture and irrigation pipes ,tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.

The thermal stability of Hastelloy B3 pipes is superior.

Nickel alloys are alloys with nickel as principal element. Complete solid solubility exists between nickel and copper. Wide solubility ranges between iron, chromium, and nickel make possible many alloy combinations.Steel plates are often used for structural and construcation applications, pressure vessels, marine and off shore equipment, and military applications. The grade, elements and parameters of a steel plate are also improtant in how it is used.

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.

These alloys of flanges are exceptionally resistant to stress corrosion cracking petrochemical applications. Moreover, the molybdenum content results in outstanding strength in solid solution alloy that considers excellent fabrication attributes.

Hastelloy C22 washers are composed of a nickel-chromium-molybdenum alloy that, like other high-nickel alloys, is highly ductile, making it easy to machine, weld, and fabricate into nuts, bolts, and screws. Hastelloy C-22 washers are made of Haynes International trademark alloy, also known as UNS N06022 or alloy 22 fasteners. C-22 fasteners are made from one of the more popular Hastelloy alloys. It is highly resistant to oxidizing/non-oxidizing chemicals, making it an excellent alloy for columns, heat exchangers and reactors in the chemical processing industry.

It is recommended that the alloy be welded in the solution annealed condition with C-276 filler metal.

The high molybdenum content of Hastelloy?* C276 provides the alloy with its excellent resistance to pitting and crevice corrosion.
