NXF UNS N10276/2.4819/NiMo16Cr15W/Alloy C-276 DN15-1200 Class3000-9000 Nickel Alloy C-276 Forged Fitting Socket Welding Union

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.

Socket weld union is a forged highpressure pipe fitting, also known as union. It consists of two body halves and a union nut, serving as a detachable piping connector. Both ends adopt socket weld connection. Pipes are inserted into the socket bore and fixed by outer fillet welds. Sealing is achieved through metaltometal contact of the internal sealing faces. The pipeline can be separated by loosening the union nut for maintenance, disassembly, or replacement of instruments and valves.

It complies with standards including ASME B16.11, MSS SP83 and GB/T14383, with pressure classes of Class 3000, 6000 and 9000, suitable for smallbore highpressure process pipelines. It is integrally forged with compact structure. The sealing surface is precision machined with tight dimensional tolerance and stable pressure resistance. Made of nickel alloy, the fitting has excellent corrosion resistance and can operate steadily under corrosive and hightemperature working conditions, featuring good weldability and reliable sealing.

It is widely used in highpressure pipelines of chemical, oil & gas, energy and water treatment industries, especially for instrument lines, sampling lines, valve connections and piping sections requiring regular disassembly and maintenance.

1. Raw Material Inspection

Check documents, appearance and perform sampling NDT for nickel alloy billets. Verify marks, mechanical and chemical properties to meet order requirements and complete traceability marking.

2. Cutting & Blanking

Cut billets according to drawing dimensions, remove burrs and oxide residues, ensure forging allowance meets process requirements.

3. Heating & Forging

Heat billets to specified temperature, forge the body halves and nut blanks with moulds. Control forging pressure and time to achieve uniform internal structure.

4. Heat Treatment

Conduct heat treatment in accordance with nickel alloy specification to relieve forging stress, optimize metallographic structure and stabilize mechanical properties.

5. Sand Blasting Cleaning

Remove scale and oil contamination on blank surface to get clean uniform surface for subsequent machining and inspection.

6. CNC Machining

Machine socket bore, end face, threads and precision sealing faces. Ensure socket depth, thread accuracy, sealing surface roughness and dimensional tolerance comply with standard drawings.

7. Dimensional Inspection

Fully inspect critical dimensions with calipers, depth gauges, thread gauges and other tools, record data. Isolate and rework out-of-spec products.

8. NDT Inspection

Carry out non-destructive testing to detect surface and internal defects such as cracks and inclusions. Mark and dispose non-conforming parts separately.

9. Surface Treatment

Perform pickling, polishing or other treatments as required to meet anti-corrosion and appearance requirements.

10. Final Inspection & Assembly Test

Recheck appearance, marking and documents, verify standard, pressure class and specification information. Trialassemble components to check thread engagement and fitting of sealing surfaces.

11. Marking & Packaging

Mark as required, apply protective packaging and transfer to warehouse for delivery.
