Nickel Alloy Pipe Fittings
The integrity of a high-performance piping system is only as strong as its weakest joint. 28Nickel supplies premium nickel alloy and superalloy pipe fittings engineered for leak-proof performance in the most aggressive chemical processing, offshore marine, and high-temperature aerospace environments. We offer a complete range of butt-weld and forged fittings to match your exact piping specifications.
Available Alloy Grades for Pipe Fittings
Matching the fitting material exactly to your pipe is critical to avoid galvanic corrosion and ensure uniform thermal expansion across the pipeline. We stock and manufacture fittings in the industry's most resilient corrosion and heat-resistant superalloys.

Explore our specific pipe fitting categories below. All products are available in seamless or welded construction, conforming to strict ASME and ASTM dimensional and material standards.
Elbows (45° & 90°)
Long radius (LR) and short radius (SR) elbows designed to change the direction of flow smoothly, minimizing pressure drop in highly corrosive fluid transport.
Tees (Equal & Reducing)
Essential for branching piping systems. We supply both equal tees (same diameter) and reducing tees to accommodate complex chemical processing manifolds.
감속기
Concentric and eccentric reducers engineered to transition flow between different pipe sizes while maintaining system pressure and structural integrity.
Pipe Caps
Heavy-duty end caps welded to the end of a pipe run to dead-end the flow, providing a secure, leak-proof seal in high-pressure gas and liquid lines.
We supply both Butt-Weld Fittings (ideal for larger diameters and smooth flow) and Forged Fittings (Socket-Weld and Threaded, for high-pressure, small-diameter applications).
| Fitting Type | Dimensional Standard | Typical Characteristics |
|---|---|---|
| Butt-Weld (Seamless) | ASME B16.9 | Sizes 1/2" to 24". Schedules 10S, 40S, 80S, 160. Ideal for critical, high-stress piping. |
| Butt-Weld (Welded) | ASME B16.9 | Sizes up to 48"+. 100% X-ray tested welds. Cost-effective for large-diameter exhaust/fluid lines. |
| Forged Socket-Weld | ASME B16.11 | Pressure classes 3000#, 6000#, 9000#. Used in small bore (<= 2") high-pressure networks. |
| Forged Threaded (NPT) | ASME B16.11 | Pressure classes 2000#, 3000#, 6000#. Quick assembly for instrumentation and sampling lines. |
