Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

Hastelloy tubing is suitable for applications in the chemical processing, pharmaceutical, agricultural, food, petrochemical and power industries. Hastelloy piping is often specified for highly corrosive industrial applications and is often used in processes where chloride is a component.

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 X pipe bend finds use in petrochemical process equipment and gas turbines in the hot combustor zone sections. Also used for structural components in industrial furnace applications because of the excellent oxidation resistance.

Alloy X pipe bend is equally suitable for use in jet engine tailpipes, afterburner components, turbine blades, nozzle vanes, cabin heaters, and other aircraft parts.

Hastelloy C-276 has superior resistance to localized corrosion as well as oxidizing.C276 alloy is suitable for many chemical process applications.

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 C276 has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.

Although Alloy C276 plate has a higher rate of work hardening compared to its austenitic counterpart, in-process annealing may be required if nickel alloy C276 plate is to be work hardened to a higher degree. Solution annealing may be required if the deformation of the nickel C276 strip exceeds 15%.

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.

Alloy C276 is increasingly used in aggressive or corrosive environments where other alloys fail.

Hastelloy C276 material is designed with good mechanical properties. They have a minimum tensile strength of 601Mpa and a minimum yield strength of 204Mpa. This material makes the alloy easy to machine and elongate.

2.4819 has very good resistance to pitting, crevice corrosion and stress corrosion cracking, C276 is worth mentioning for its excellent resistance to aggressive media under oxidizing and reducing conditions.

Hastelloy C2000 flanges are a special alloy for securing chemical process equipment under different conditions, including streams contaminated with ferric ions.

C2000 flanges have better temperature capabilities in hydrofluoric, sulfuric, and diluted hydrochloric acids due to the addition of copper.

Hastelloy G-30 is an improved version of nickel-chromium-iron-molybdenum-copper alloy G-3. With higher chromium, added cobalt and tungsten, the G-30 shows superior corrosion resistance over most other nickel and iron based alloys in commercial phosphoric acids as well as complex environments containing highly oxidizing acids. The resistance of the alloy to the formation of grain boundary precipitates in the heat-affected zone makes it suitable for use in most chemical process applications in the as-welded condition.

Hastelloy fasteners such as bolts, screws, nuts and threaded rods are ideal for use in a variety of moderately to severely corrosive acid environments. The most common grade of Hastelloy fasteners is Hastelloy C276 (2.4819), which is one of the most versatile corrosion-resistant nickel alloys, surpassing Inconel or Monel. There are also other special grades of Hastelloy fasteners that can address more niche corrosion problems.

G30 alloy can prevent the formation of grain boundary precipitation in the heat affected zone of welding

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.

Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Like other nickel alloys, HASTELLOY C-22 alloy is fairly ductile, has excellent weldability, and is easily fabricated into industrial parts. It is available in sheet, sheet, strip, billet, bar, wire, tube and tube. Typical applications may include: reactors, heat exchangers and columns.

C276 is a nickel-molybdenum-chromium superalloy with tungsten added, designed for excellent corrosion resistance in a variety of harsh environments. The high nickel and molybdenum contents make nickel steel alloys particularly resistant to pitting and crevice corrosion in reducing environments, while chromium is resistant to oxidizing media.

The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Hastelloy C276 low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance of welded structures. This nickel alloy resists the formation of grain boundary deposits in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded state.
