NXF UNS N10276/2.4819/NiMo16Cr15W/Alloy C-276 DN15-1200 Class3000-9000 Nickel Alloy C-276 Forged Fitting Thread Square Head Plug

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 square head plug is a forged sealing fitting for highpressure piping systems. It is designed with a square driving head at one end and standard tapered external threads at the other end. It is used to seal unused female threaded ports on pipelines, valves and fittings. It can serve as permanent closure, or temporary blank-off for test ports, inspection ports and drain ports.

The square head is its distinctive feature, which can be gripped directly by wrench or socket for torque operation. It enables uniform force during assembly and disassembly, and works well in confined piping spaces. Selfsealing is achieved by engagement of tapered male and female threads. No hot work is required during installation. It is highly suitable for positions requiring repeated opening or inspection, pressure relief and medium cleaning, simplifying maintenance and eliminating hot-work hazards.

Manufactured strictly in accordance with ASME B16.11 standard for forged threaded fittings, this fitting supports multiple pressure classes and is mainly designed for small-bore highpressure piping. Made of nickel alloy, it has outstanding corrosion resistance against strong acid, sulfurcontaining fluids, chlorides and other corrosive media. It can maintain stable strength and toughness under continuous high temperature conditions, resisting embrittlement, deformation and thread leakage.

With reliable sealing performance and easy disassembly, this fitting is suitable for harsh working conditions with high requirements on corrosion resistance and hightemperature mechanical properties. It is widely used in process piping and instrument impulse lines of fine chemical, oil & gas, refining, new energy and power industries.

1. Raw Material Inspection: Verify the nickel alloy raw material, inspect appearance and dimension, reject blanks with cracks and defects.

2. Cutting: Cut raw material into blanks that meet forging specifications.

3. Heating & Forging: Heat blanks to proper temperature and forge into square head plug rough parts by dies.

4. Heat Treatment: Relieve forging residual stress and improve mechanical performance.

5. Trimming & Shaping: Remove flash and excess material, calibrate square head profile and thread base.

6. Sandblasting: Remove oxide scale and get uniform surface finish.

7. Machining: CNC machine end face and tapered external threads, finish four bearing surfaces of square head, strictly control thread precision and square dimension.

8. Nondestructive Testing: Carry out NDT to detect internal and surface flaws.

9. Final Dimensional Inspection: Check thread size, wall thickness, square dimension and other parameters against standards.

10. Marking: Stamp specifications, pressure class and identification marks on fittings.

11. Anti-rust Treatment & Packaging: Apply anti-rust coating, protect threads, pack and store finished goods.
