Incoloy 800 Pipes
Incoloy 800 pipes, also known as Alloy 800 pipe or UNS N08800 Pipes, are nickel-iron-chromium alloy pipes designed for high-temperature applications. They have a stable austenitic structure, excellent oxidation resistance, and reliable performance at temperatures up to 600°C and beyond. These pipes are widely used in heat treatment furnaces, chemical processing plants, power generation systems, and nuclear applications, making them a reliable choice for demanding industrial environments.
Incoloy 800 Pipes Price
The price of Incoloy 800 pipe in India varies by pipe type, dimensions, wall schedule, and order volume. Here is a practical breakdown to support procurement planning.
- Approximate price range: Seamless Incoloy 800 pipes are priced between INR 2,500 and INR 6,000 per kg in India. Welded variants are more economical, ranging from INR 1,800 to INR 3,500 per kg depending on specification.
- Cost per foot (approx.): A standard 1-inch Incoloy 800 seamless pipe (Schedule 40) costs approximately INR 800 to INR 2,000 per foot. Larger diameters and higher wall schedules increase this cost proportionally.
- Factors affecting price: The 3 key factors that influence the final Incoloy 800 pipe price are raw material costs (particularly nickel and chromium); the pipe type and surface finish (seamless pipes cost more than welded); and order quantity, along with any additional certifications such as NACE, PED, or third-party inspection requirements.

How To Choose The Right Incoloy 800 Pipes Supplier?
Selecting the right Incoloy 800 pipe supplier directly affects material quality, project timelines, and procurement cost. Evaluate the following criteria before placing an order.
Evaluate the manufacturer's technical expertise: Check that the manufacturer has practical experience with nickel alloys and high-temperature grades. Ask for project references to confirm their expertise.
Check grade availability and product range: A reliable alloy 800 pipe supplier should offer a complete range of diameters, schedules, and pipe types. Wide availability of standard and non-standard dimensions reduces lead times and avoids substitutions.
Verify quality certifications and testing capabilities: Certifications such as ISO 9001, PED, and NACE MR0175 are essential. In-house capabilities like PMI, hydrostatic testing, and ultrasonic inspection confirm that each pipe meets the required standard.
Examine the strength of raw material sourcing: The quality of the raw billets directly impacts the pipe’s final strength. Make sure mill-certified material is sourced from approved suppliers before you place an order.
Assess customisation capabilities: Many projects require specific OD, wall thickness, or end-finish combinations. Confirm the manufacturer can produce to custom dimensions without compromising dimensional tolerances.
Review delivery timelines and supply capacity: For large projects, steady supply is just as important as quality. Make sure the quoted price of Incoloy 800 pipe includes a realistic delivery schedule and sufficient stock to meet the requirements.

Incoloy 800 Pipes FAQ's
The price of Incoloy 800 pipes in India ranges from INR 1,800 to INR 6,000 per kg, depending on pipe type (seamless or welded), outer diameter, wall schedule, and order quantity. Non-standard sizes or added certifications will increase the cost.
Incoloy 800 pipe is a nickel-iron-chromium alloy designed for high temperatures. It consists of about 30–35% nickel and 19–23% chromium, and it can resist rusting, carbon buildup, and corrosion at temperatures of 600°C and higher.
Incoloy 800 pipes are manufactured to ASTM B407 and ASME SB407 standards. These cover both seamless and welded forms. The UNS designation is N08800.
Incoloy 800 pipes are available from ½ inch to 24 inches in outside diameter, with wall schedules ranging from Sch 5S to Sch XXS. Standard lengths are 6 metres and 12 metres. Custom sizes are available on request.
Alloy 800 pipe is available in various types, like seamless, welded, and EFW (electric fusion welded). Seamless pipes are ideal for high-pressure applications. For lower-pressure applications, welded and EFW types are more effective.
Seamless pipes are extruded from solid billets, resulting in a consistent wall thickness and higher pressure ratings. The welded pipes are manufactured by rolling and welding a flat strip or plate, making them more affordable but with a slightly reduced pressure capacity. The decision is based on operational pressure, temperature, and budget limits.
