Super Duplex Steel Pipe Fittings

Super duplex steel pipe fittings are high-alloy connectors manufactured from a dual-phase microstructure of austenite and ferrite. These fittings are available in grades like UNS S32750 and UNS S32760. Super duplex fittings consist of 24-26% chromium, 3-4% molybdenum, and a high nitrogen concentration. This composition gives twice the strength of standard austenitic stainless steel, along with better resistance to pitting, crevice corrosion, and stress corrosion cracking. Super duplex pipe fittings are widely used in offshore oil and gas, chemical processing, desalination, and marine applications where systems must perform in harsh conditions.

Super Duplex Steel Pipe Fittings Prices

The price of super duplex pipe fittings depends on grade, wall schedule, size, and order quantity. Here's a clear breakdown to help you plan your procurement correctly.

Approximate Price Range

Super duplex steel pipe fittings cost between Rs. 1,012.5 and Rs. 1,620 per piece for standard grades and sizes. Heavy-schedule fittings and specific grades will cost more due to raw material content and manufacturing complexity.

Factors Affecting Price

• Grade selection: Grades like S32750 and S32760 cost more due to their higher chromium, molybdenum, and nitrogen content.

• Size and wall schedule: Fittings in larger NPS or thicker schedules, such as SCH 80S, SCH 160, or XXS, need more material and machining, which results in higher per-unit costs.

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

How To Choose The Right Super Duplex Steel Pipe Fittings Supplier And Manufacturer?

Choosing the right super duplex pipe fittings supplier directly affects material quality, delivery timelines, and project compliance. Evaluate 4 key areas before placing an order.

Selecting the right supplier and manufacturer

Shortlist super duplex pipe fittings suppliers who hold documented mill certifications and maintain full material traceability from heat to fitting. A supplier with an established export record and a broad grade portfolio, such as S32750 and S32760, reduces sourcing risk on large or long-term projects.

Technical considerations

Confirm that the super duplex steel pipe fittings supplier can provide the exact grade, size, wall schedule, and end connection the system requires. Request Material Test Reports (MTRs) and verify that pressure ratings align with the system design before finalising an order.

Evaluating supplier credibility

Check ISO certifications, third-party audit reports, and available customer references. A reliable super duplex pipe fittings manufacturer and supplier provides all these certificates.

Procurement strategy

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