Inconel Pipe Grades

Inconel pipe comes in 2 primary grades: Alloy 600 and 625.

Inconel 600 Pipe (Alloy 600)

Alloy 600 (UNS N06600) contains 72% min nickel and resists oxidation up to 1093 o C (2000 °F).

Inconel 625 Pipe (Alloy 625)

Alloy 625 (UNS N06625) adds 8-10% molybdenum and 3.15-4.15% niobium for superior pitting and fatigue resistance.

Inconel Pipe Industrial Applications

Oil and Gas Industry

Inconel pipe handles subsea flowlines, sour gas service per NACE MR0175, and downhole tubing.

Chemical Processing

Acid-handling piping and heat exchanger tubing in sulphuric acid environments use Inconel alloy pipe.

Power Generation

Superheater tubing and steam piping rely on the creep resistance of Inconel 600 and 625 pipe.

Aerospace and Defense

Inconel pipe serves exhaust systems and turbine piping.

Marine Engineering

Seawater piping and desalination systems use Inconel 625 pipe for chloride corrosion performance.

Frequently Asked Questions

What are the ASTM Specifications for Inconel Pipe?+
Inconel seamless pipe follows ASTM B167 (Alloy 600) and ASTM B444 (Alloy 625). Welded pipe follows ASTM B517 and B705.
What Sizes does Inconel Pipe Come In?+
Inconel pipe is available from 1/8" to 24" NPS in schedules 5S through 160.
Is Inconel Pipe Stronger than Stainless Steel Pipe?+
Inconel 625 pipe has 120 ksi tensile strength versus 75 ksi for 316L. It retains strength above 600 degrees C.
How is Inconel Pipe Welded?+
Inconel pipe is welded by GTAW (TIG) with ERNiCrFe-7 or ERNiCrMo-3 filler. Interpass temperature stays below 150 degrees C.
What is the Price Range for Inconel Pipe?+
Inconel pipe costs in India range from Rs. 1700 to Rs. 3852, whereas in the United States they are $10-60/kg for Alloy 600, Rs. 200-4400, and $25-100/kg for Alloy 625.
What is the Difference Between Inconel Seamless and Welded Pipe?+
Seamless pipe has no weld seam and suits high-pressure service. Welded pipe costs less for larger diameters.
Which Inconel Grade is Best for High-Temperature Pipe Service?+
Inconel 601 rates highest at 1260 °C. Alloy 600 serves up to 1093 °C. Alloy 625 suits combined corrosion and heat needs.
What is the Material Code for Inconel Pipe?+
The ASME group is P-43. The HS code is 7507.12 for Alloy 600 and 625 pipe.
