Inconel Pipe Fittings

Inconel pipe fittings are high-performance connectors manufactured from nickel-chromium-based superalloys. Available in grades such as Inconel 600, 625, and 718, these fittings consist of 58–72% nickel, 14–23% chromium, and various levels of molybdenum and iron. This composition provides strong resistance to oxidation, high-temperature corrosion, and mechanical stress. Unlike standard stainless steel, Inconel maintains its strength at temperatures above 1000°C, making it suitable for extreme heat conditions. The fittings are available as elbows, tees, reducers, caps, and stub ends, in sizes from 1/2" NB to 24" NB, and follow ASTM B366 and ASME SB366 standards. They can handle pressures up to 9000 LBS, making them suitable for both low- and high-pressure applications. These fittings are commonly used in aerospace, chemical processing, oil and gas, nuclear and power-generating applications, where standard alloys fail to perform consistently over time.

Inconel Pipe Fittings Prices

Inconel pipe fitting prices depend on grade, wall schedule, size, and order quantity. Here is a clear breakdown to help you plan procurement accurately.

Approximate price range:

Inconel pipe fittings are priced between Rs. 4,050 and Rs. 6,750 per piece for standard grades and sizes. Heavy-schedule or specialised grade fittings will cost more.

Factors Affecting Price:

• Grade selection: Higher-alloy grades such as Inconel 625 and 718 carry a premium due to elevated nickel and molybdenum content.

• Size and wall schedule: Larger NPS sizes and thicker schedules, such as Sch 80 or Sch 160, require more raw material and machining time, increasing the per-unit cost.

• Order quantity: Bulk orders qualify for volume-based pricing. Share the grade, size, and quantity to receive a project-specific quote.

How To Choose The Right Inconel Pipe Fittings Supplier And Manufacturer?

Choosing the right Inconel pipe fitting suppliers directly affects material quality, delivery reliability, and project compliance. Evaluate 4 key areas before placing an order.

Selecting The Right Supplier And Manufacturer

Shortlist Inconel fittings suppliers who hold documented mill certifications and maintain full material traceability from heat to fitting. A supplier with a verified export record and a broad grade portfolio, such as Inconel 600, 625, and 718, reduces sourcing risk on large or long-term projects.

Technical Considerations:

Confirm that the Inconel pipe fittings supplier can provide the exact grade, size, wall schedule, and end connection the system requires. Request for Material Test Reports (MTRs) and make sure the pressure ratings match your system design before you place the order.

Evaluating Supplier Credibility:

Check ISO certifications, third-party audit reports, and available customer references. A credible Inconel pipe fittings manufacturer provides all documentation without delay.

Procurement Strategy:

For large-volume projects, negotiate staggered delivery schedules and locked pricing to control cost. Request a detailed quote that separately breaks down material cost, surface finish charges, testing fees, and packaging.
