Hastelloy Pipes

Hastelloy pipes are high-performance nickel-based alloy pipes engineered for extreme corrosion and heat resistance. The alloy family covers multiple grades, including Hastelloy C276, C22, B2, B3, and X, each tailored to specific chemical and thermal environments. This material is defined by three properties: outstanding resistance to oxidising and reducing media, excellent mechanical strength at high temperatures, and reliable weldability without post-weld heat treatment. Hastelloy pipes are used in chemical processing, oil & gas, aerospace, and pharmaceutical industries, where carbon steel and standard stainless steel fail within months.

Hastelloy Pipe Prices

Hastelloy pipe prices vary with grade, size, wall schedule, and order volume. Understanding these cost drivers early supports accurate project budgeting.

Approximate Price Range:

Hastelloy pipe prices in India range between Rs. 3,500 and Rs. 6,000 per kg for standard grades. The final rate is determined by grade, outside diameter, wall schedule, and order quantity.

Factors Affecting Price:

• Grade and alloy content: Hastelloy C276 and C22 contain high molybdenum and chromium levels, which increase the raw material costs above simpler nickel grades.

• Wall thickness and schedule: Heavier schedules, such as Sch 80S and Sch 160S, consume more alloy per unit length, increasing cost per kg directly.

• Manufacturing method: Seamless Hastelloy pipes are more costly than welded equivalents due to smaller production volumes and increased tooling requirements.

• Market fluctuations: Nickel and molybdenum prices influence raw material costs. Before placing bulk buy orders, confirm current LME pricing.

Hastelloy Pipes Size Chart

Hastelloy pipe sizes range from NPS 1/8" through 12", covering OD values from 10.3 mm to 323.9 mm to suit standard industrial piping layouts.

Schedule Chart Of Hastelloy Pipes

Wall thickness increases with schedule number. A higher schedule delivers a thicker wall and a higher pressure rating. Use this chart to confirm the correct wall specification for your operating pressure and temperature.

How To Choose The Right Hastelloy Pipe Supplier And Manufacturer?

Selecting the right Hastelloy pipe suppliers directly affects pipe integrity, project timelines, and total procurement cost. Evaluate these 4 areas before finalising a vendor.

Selecting The Right Supplier And Manufacturer:

Confirm that the manufacturer produces Hastelloy pipes in the exact grade and NPS required for your project. Not every facility handles nickel-based alloys. Verify production capabilities for alloy C276 pipe (UNS N10276), C22, and B2 grades before issuing an RFQ.

Technical Considerations:

Match the grade to the service environment, whether chloride exposure, acidic media, or elevated pressure. Request a material test certificate (MTC) confirming chemical composition and mechanical properties. Confirm compliance with ASTM B622 for seamless Hastelloy pipes and ASTM B619 for welded variants. Custom wall schedules can have 8–12-week lead times; check stock availability early in the planning phase.

Evaluating Supplier Credibility:

A reliable Hastelloy pipe supplier holds at least ISO 9001 certification. Every pipe batch must carry a heat number traceable to the originating mill. This is mandatory for project documentation and quality audits. We at Piping Material maintain full traceability across all Hastelloy pipe supplies. Request references from chemical processing, oil and gas, or pharmaceutical projects, as these carry the most weight when evaluating a nickel alloy piping vendor.

Procurement Strategy:

Send a clear RFQ that specifies the grade (UNS number), NPS, schedule, finish, governing standard, and quantity. Evaluate at least three supplier proposals based on pricing, lead time, MTC availability, and order quantity. For bulk orders, plan a pre-dispatch inspection (PDI) or third-party inspection (TPI) at the manufacturer's location.
