Hastelloy C22 Pipes

Hastelloy C22 pipe is a nickel-chromium-molybdenum alloy pipe widely used in highly corrosive industrial environments. It is also referred to as alloy C22 pipe or UNS N06022; it contains 20–22.5% chromium and 12.5–14.5% molybdenum, which provides it with high resistance to oxidising and reducing media. Industries such as chemical processing, oil and gas, pharmaceuticals, and desalination rely on Hastelloy C22 pipes for their long service life, weldability, and ability to handle both wet and dry corrosive conditions without failure.

Hastelloy C22 Pipe Price

The Hastelloy C22 pipe price depends on size, wall thickness, pipe type, and order quantity. The following factors directly affect the final cost.

Approximate Price Range

Hastelloy C22 pipes are typically priced between INR 3,500 and INR 6,000 per kilogram in India. Seamless variants cost more than welded types due to the manufacturing process involved.

Cost Per Foot (Approx.)

The cost per foot ranges approximately from INR 800 to INR 3,500, depending on the schedule, diameter, and form. Thicker walls and larger NPS sizes push the cost toward the higher end.

Factors Affecting Price

4 key factors affect the hastelloy c22 pipe price: raw material costs (nickel and molybdenum market rates), pipe type (seamless vs. welded), wall thickness and schedule, and surface finish (pickled, polished, or mill finish). Each of these can shift the per-unit cost significantly.

How To Choose The Right Hastelloy C22 Pipe Supplier?

Selecting the right supplier affects material quality, delivery speed, and total project cost. Evaluate these 6 criteria before placing any order.

Evaluate The Manufacturer's Technical Expertise

Check if the supplier has direct metallurgical knowledge of C22. This alloy requires precise heat treatment and controlled annealing. Ask about prior experience with the grade and how processing quality is maintained batch to batch.

Check Grade Availability And Product Range

A dependable hastelloy C22 pipe supplier should stock all 6 pipe types across multiple schedules. Limited availability often means the buyer must compromise on size or form, which is rarely acceptable in engineered applications.

Verify Quality Certifications And Testing Capabilities

ISO 9001 certification is the baseline. Also, verify in-house testing: hydrostatic testing, PMI, ultrasonic testing, and hardness checks. Request mill test reports with full material traceability before confirming the order.

Examine The Strength Of Raw Material Sourcing

The final pipe quality depends on the source of raw coils or billets. Approved and certified mills reduce variability. Consistent raw material sourcing ensures consistent mechanical and chemical properties across all supplies.

Assess Customisation Capabilities

Standard sizes often do not meet project specifications. A supplier with in-house cutting, threading, and polishing facilities can deliver custom lengths or bevel ends quickly, without adding a third-party step.

Review Delivery Timelines And Supply Capacity

Confirm stock availability, dispatch timelines, and minimum order quantities before finalising. At Metline Industries, a ready stock of Hastelloy C22 pipes is maintained for both domestic and export supply. Even with stock in hand, confirm lead times and export documentation requirements early to protect the project schedule.
