Inconel 601 Pipes Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Inconel 601 pipe (N06601, Werkstoff 2.4851) to ASTM B167 from Mumbai, to customers across India and in more than 40 export markets.
Inconel 601 pipe carries heat rather than pressure. It is the burner line, the combustion-air duct, the flare tip and the hot-gas connection on a thermal oxidiser – lines that run hot, see the flame or its exhaust, and cool down every time the unit stops. The 1.0–1.7% aluminium in 601 forms an oxide that survives those cycles, which ordinary stainless pipe and even 600 do not.

Mechanical and Physical Properties
At room temperature annealed 601 pipe runs roughly 550–760 MPa tensile, but its design value is oxidation resistance to about 1200°C with good strength under cyclic heating. Schedule is set by the modest pressures of hot-gas service, not by strength.
Industry Applications
Why Inconel 601 pipe
The argument for 601 pipe is scale that stays put. A hot-gas line that cycles loses wall every time its oxide spalls; 601’s aluminium-stabilised oxide stays attached, so the line keeps its wall longer. It is not a high-strength pipe above 1000°C – a line that carries real load at that temperature belongs in 617 – and it is not a wet-corrosion alloy.
| Industry | Typical use |
|---|---|
| Petrochemical | Flare tips, catalyst regenerator lines and thermal reactor piping. |
| Environmental | Hot-gas ducting and connections on thermal oxidisers and incinerators. |
| Industrial heating | Burner lines and combustion-air piping at the hot end of a furnace. |
| Heat treatment | Radiant tube assemblies and furnace gas lines. |
Testing and Certification
Pipe is supplied with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Hydrostatic, ultrasonic and dye-penetrant testing and positive material identification are available on request, with third-party inspection under our ISO 9001:2015 system.
