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.
Threaded pipe nipple is a forged straight threaded fitting, made as a short pipe segment with external threads on the ends. It is used for straight connection of pipelines, pipeline extension, and assembly connection with valves, instruments and other internally threaded fittings. Manufactured from nickel alloy and produced in accordance with international standards such as ASME B16.11, it supports mainstream pipe thread standards including NPT and BSP, and meets sealing and connection requirements under highpressure working conditions.
This fitting features a simple and compact structure with easy installation. Sealing is achieved by thread engagement without welding, which facilitates disassembly and maintenance. It can be flexibly arranged in limited piping space. Nickel alloy delivers outstanding corrosion resistance and hightemperature resistance. It can resist erosion from various corrosive media and avoid leakage, embrittlement or rust failure during long-term continuous service, ensuring stable operation of the piping system.
Threaded pipe nipples are available in various lengths for different onsite spacing requirements. They are widely used in process piping systems of oil & gas, chemical and energy industries. They are commonly adopted for short-distance connection, branch transition and instrument impulse lines of corrosive medium pipelines and high-pressure fluid pipelines, serving as a highly versatile basic connector in threaded piping systems.



1. Raw Material Inspection
Verify nickel alloy bar stock by spectrum test and visual inspection. Check for cracks, laminations and inclusions, confirm dimensions and keep inspection records.
2. Cutting
Cut the raw material according to finished length requirements, ensure flat end faces and proper machining allowance.
3. Blank Forming
Produce blanks by forging or precision turning as required, control outer dimensions and prevent deformation and material shortage.
4. Blank Re-inspection
Check blank shape and wall thickness, separate non-conforming parts with forging defects or out-of-tolerance dimensions.
5. Sandblasting
Remove oxide scale and oil contaminants by sandblasting to prepare clean surface for precision machining.
6. CNC Machining
Finish turning of outer diameter and end faces, machine external threads on both ends, strictly control thread form, taper and dimensional tolerance.
7. Thread Inspection
Test threads one by one with thread ring gauges to ensure thread accuracy and interchangeability.
8. Hydrostatic & Pneumatic Test
Carry out pressure test per specified pressure class, hold pressure and check for leakage on fitting body and threads.
9. Deburring and Surface Cleaning
Remove metal chips, oil and burrs to achieve smooth surface.
10. Final Inspection and Marking
Recheck all dimensions and appearance. Mark specifications and standards on qualified fittings.
11. Packaging and Warehousing
Protect threaded areas, pack separately and put into storage.
