Inconel Tubing

DEFINITION OF Inconel Tubing : Inconel Tubing is a high-strength, high-temperature and corrosion resistant nickel-chromium alloy tubing.

Inconel Tubing is a nickel-chromium alloy tubing with good oxidation resistance at high temperatures. It resists cracking and corrosion caused by stress and caustic substances. Often used for thermocouple protection tubing. It’s temperature range is -132°C to 650°C (-205°F to 1200°F).

Since the mid-1980s, Dynamic Flowform has used the precision flowforming process to produce  inconel tubing to net or near-net shape. Flowforming is a cold forming process for the production of seamless, dimensionally precise tubular components. Beside offering lower cost alternatives to machining from solid bar, due to the cold working of the material, the microstructure of flowformed inconel tubing is superior to that of bar or sheet. Flowformed inconel tubing is used in military, nuclear and industrial applications.

The flowforming process offers the designer an opportunity to explore the very high tensile strength, with excellent ductility. The grain refinement and grain directionality imparted by the flowforming process is very advantageous, too. The extremely fine grain structure (ASTM 10-12) is what one would expected from solution heat treating a heavily cold-worked (70% wall reduction) structure at 1750 F post-flowform heat treatment.

Customers can take advantage of the flowforming characteristics by incorporating them into their designs. In addition to the benefits listed above, flowforming produces inconel tubing components with seamless constructions.

Our flowformed components range in size from diameters of 0.866" to 25.600" (22-650mm), wall thicknesses from 0.006" to 0.600" (0.15-15mm) with lengths up to 26.5 ft. (8 meters). Since flowform poses no limitations on the relationship between components diameter and wall thickness, quite often we produce large diameters with precise thin walls.
