Description
Nickel 201 Seamless Pipe – High-Purity ASTM B163 Nickel Tubing for Industrial & Chemical Applications
🔹 Product Overview
The Nickel 201 Seamless Pipe is a premium-grade, high-purity nickel alloy tube engineered to meet the most demanding requirements in chemical processing, marine environments, and high-purity industrial manufacturing.
Manufactured in full compliance with ASTM B163 Nickel Pipe standards, this tubing offers exceptional corrosion resistance, high mechanical strength, and superior thermal and electrical conductivity.
Nickel 201 is the low-carbon variant of Nickel 200 (maximum carbon content ≤ 0.02%), which improves its resistance to intergranular corrosion and makes it ideal for service in environments where temperatures exceed 315°C (600°F). This reduced carbon content also minimizes graphitization, ensuring stable performance in high-temperature and reducing atmospheres.
Whether you need straight-length tubes, cut-to-size sections, or fully Nickel 201 Annealed Pipe for enhanced workability, our production capabilities ensure you get the right product for your project.

🔄 Manufacturing Process
Our Nickel 201 Seamless Pipe is produced using a carefully controlled sequence to ensure the highest purity and dimensional accuracy.
Step 1 – Raw Material Selection
-
High-purity Ni201 billets tested with spectrometry for chemical compliance.
Step 2 – Extrusion & Piercing
-
Solid billets are heated and pierced to form a hollow shell.
Step 3 – Cold Drawing
-
Pipes are drawn through precision dies to achieve final diameter and wall thickness.
Step 4 – Annealing
-
For Nickel 201 Annealed Pipe, we use controlled-atmosphere annealing to improve ductility.
Step 5 – Finishing & Inspection
-
Surface polishing, cutting, straightening, and non-destructive testing (eddy current, ultrasonic, hydrostatic).
