Super alloys or high performance alloys are available in a variety of shapes and contain elements in different combinations to obtain a specific result. These alloys are of three types that include ironbased, cobaltbased and nickelbased alloys. The nickelbased and cobaltbased super alloys are available as cast or wrought based alloys according to composition and application.
Super alloys have good oxidation and creep resistance and can be strengthened by precipitation hardening, solidsolution hardening and work hardening methods. They can also function under high mechanical stress and high temperatures and also in places that require high surface stability.
HASTELLOY(r) C276 is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.
Swage nipple is a forged reducing pipe fitting, a special component for diameter transition in piping systems. It has different sizes at both ends and is used to connect piping components with different flow sizes. Manufactured from nickel alloy and produced in accordance with standards such as ASME B16.11 and MSS SP95, it supports threaded, socket welding and other connection types to meet reducing connection requirements under high-pressure working conditions.
The fitting adopts a smooth tapered inner bore, which reduces flow resistance, turbulence, pressure drop and medium impact to ensure stable fluid transportation. It features compact structure and small installation space, suitable for instrument impulse lines, pipe branches and confined piping sections. Nickel alloy provides excellent hightemperature resistance and corrosion resistance. It can withstand various corrosive process media, maintain stable performance during longterm service and avoid erosion, leakage and failure.
Swage nipples are available in concentric and eccentric configurations for different piping layout requirements. They are widely used in process piping systems of oil & gas, chemical and energy industries for diameter transition of highpressure pipelines and corrosive medium pipelines, serving as a common reducing fitting for smallbore highpressure piping.



1. Raw Material Inspection
Verify nickel alloy billets by spectrum test and visual inspection. Check for cracks, laminations and inclusions, confirm dimensions and keep inspection records.
2. Cutting
Cut raw materials according to product specifications and reducing ratio, ensure flat end faces and proper machining allowance.
3. Heating and Forging
Heat billets in temperature-controlled furnace. Forge tapered reducing profile by closed die forging, then cool blanks following specified procedure to release stress.
4. Blank Inspection
Check blank shape and reducing transition profile, screen out blanks with cracks, shortage or deformation.
5. Sandblasting
Remove oxide scale and forging contaminants by sandblasting to get clean surface for precision machining.
6. CNC Machining
Finish turning of outer diameter, end faces and inner bore. Machine threads or socket weld grooves as required, strictly control tapered bore and dimensional tolerance.
7. Dimension & Profile Inspection
Check end sizes and transition section with special gauges, ensure smooth inner bore and tolerance compliance.
8. Hydrostatic & Pneumatic Test
Carry out pressure test per specified pressure class, hold pressure and check for leakage.
9. Deburring and Surface Cleaning
Remove metal chips, oil and burrs for smooth surface.
10. Final Inspection and Marking
Recheck all dimensions and appearance. Mark specifications and standards on qualified fittings.
11. Packaging and Warehousing
Protect threads or grooves, pack separately and put into storage.
