Hastelloy X is a nickel-based superalloy ideal for gas turbine engine, aircraft, industrial furnace, and chemical processing applications.
Furnace rolls made of this alloy were still in good condition after operating for 8700 hours at 2150 Deg. F. Furnace trays, used to support heavy loads, have been exposed to temperatures up to 2300 Deg. F. in an oxidizing atmosphere without bending or warping.
Alloy X pipe bend is known for its excellent high temperature strength withstanding up to 2200¡ãF. The alloy can also be easily fabricated with forming and welding characteristics by both manual and automatic methods.
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 X pipe bend is corrosion resistant, heat resistant and oxidation resistant, being able to withstand reducing or neutral atmospheres and oxidation.
Alloy X pipe bend offers exceptional performance in furnace rolls or other industrial furnace applications because of the alloy’s strong resistance to oxidizing, reducing and neutral atmospheres.
Hastelloy X pipe bend is widely used for a variety of chemical processing parts, including retorts, pyrolysis tubing, and muffles due to its exceptional resistance to stress-corrosion cracking.
HASTELLOY X pipe bend is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. All of the product forms are excellent in terms of forming and welding.
Although HASTELLOY X pipe bend is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking and has good resistance to carburization, excellent resistance to reducing or carburizing atmospheres.
Alloy X pipe bend is one of the most widely used nickel base superalloys for gas turbine engine components.
AMS 5754 pipe bend has no yield or tensile strength requirements, but it does require a hardness maximum and stress rupture minimums.
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).
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.
Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X pipe bend excels in both respects due to the formation of a protective, tenacious oxide film.
HASTELLOY X pipe bend also resists carburization and nitriding, two common conditions which often lead to early failure in high-temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization and whereas.
Alloy X pipe bend specimens showed no carburization at all. Of ten materials evaluated in an atmosphere of hydrogen, nitrogen and ammonia at 1100 Deg. F. and 25,00 psi for 64 days, Alloy X had a nitride case less than one-fourth as thick as the closest competitive material without intergranular attack.
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.
Modern processing systems are often a complex network of turns, elevation changes, fittings, and more.
When standard 90-degree elbows won¡¯t work with your system design or space requirements, bent pipes and tubing are an excellent routing option.
As with most piping considerations, understanding the ideal uses for bent pipe in your design or project is essential to the proper operation of the finished system.
Pipe bending allows systems to minimize pressure changes while still routing materials through complex piping systems.
As most bent pipes do not alter the ends of the piping, pipe bends are often easy to implement within a processing system using standard welding processes, flanges, or other connection methods.
The sheer variety of pipe bend sizes and materials also make them suitable for routing everything from hot or caustic liquids to maintaining pressure and movement in high viscosity liquids or those with suspended solids, such as Oil Sands slurry lines which contains a high concentration of silica sand.
As the most pipe bending methods are quite cost-efficient, using bent pipes and tubes will have a minimal impact on the overall design budget when using the ideal length and sizing for your application.
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.
Each method has unique benefits and will determine the degree of bending possible and the final shape of the pipe.
Pipe or tube is bent using a combination of dies and other various components working in a rotary action.
This action draws the pipe or tube forward making the desired bend.
Rotary draw bending can also utilize mandrels.
Bending a pipe or tube using a stationary die while a counter die bends the material around the stationary die.
