Nickel Alloy Pipe & Tube
Nickel alloy pipes and tubes form the critical arteries of the world's most demanding industrial systems. Whether you are transporting highly corrosive hydrofluoric acid across a refinery or engineering a high-pressure heat exchanger for a nuclear facility, 28Nickel supplies premium tubular products designed to survive where standard stainless steel fails.
Available Alloy Grades for Pipe & Tube
The longevity of your fluid transport or heat exchange system depends entirely on the material's resistance to its environment. We supply tubular products in a comprehensive range of corrosion and heat-resistant superalloys, ensuring your operations run safely and continuously.

Understanding the Difference: Pipe vs. Tube
While often used interchangeably in casual conversation, "Pipe" and "Tube" serve entirely different engineering functions and are measured using different dimensional standards.
| Pipe (Fluid Transport) | Tube (Mechanical & Heat Transfer) |
|---|---|
| Purpose: Designed primarily to transport fluids and gases across distances (e.g., chemical pipelines, water lines). | Purpose: Designed for structural applications, instrumentation, and heat transfer (e.g., heat exchangers, boilers, hydraulic lines). |
| Measurement: Specified by Nominal Pipe Size (NPS) and a wall thickness Schedule (Sch). (e.g., 2" NPS Sch 40). | Measurement: Specified by exact Outside Diameter (OD) and exact Wall Thickness (WT). (e.g., 1.500" OD x 0.065" Wall). |
| Tolerances: Looser dimensional tolerances compared to tubing. | Tolerances: Extremely strict tolerances on OD, ID, and wall thickness to ensure proper fitment into tube sheets and fittings. |
Browse Manufacturing Methods
Depending on your system's pressure requirements and budget, we offer tubular products in both seamless and welded constructions.
Seamless Pipe & Tube
Extruded and pierced from solid billets. Offering the highest pressure ratings and absolute structural integrity with no weld seam vulnerabilities. Essential for critical downhole operations, extreme-pressure chemical reactors, and aerospace hydraulic lines.
Welded Pipe & Tube
Formed from premium rolled plate or sheet and welded longitudinally. 100% radiographed and tested. Highly cost-effective for large-diameter fluid transport, exhaust systems, and lower-pressure industrial manifolds.
