Alloy C-276 introduction

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 Welding Cap Introduction

Socket weld cap is a forged highpressure pipe fitting, which is used to seal the end of pipeline, block medium flow and protect pipe ends. It is an end sealing component for piping systems. It adopts socket weld connection. The pipe is inserted into the socket bore of the fitting, and fillet welding is carried out on the outer side for sealing and fixing.


It is manufactured in accordance with ASME B16.11, GB/T14383 and other standards, with pressure classes of Class 3000, 6000 and 9000, suitable for smallbore highpressure pipelines. It is integrally forged with compact structure and strict dimensional tolerance, offering stable pressure resistance. Made of nickel alloy, the fitting has outstanding corrosion resistance and can work stably under harsh corrosive and high-temperature conditions. It features good weldability, easy installation and reliable sealing.


It is widely used in highpressure process pipelines of chemical, oil & gas, energy, water treatment and other industries, for permanent or temporary sealing of pipe ends and reserved connections, as well as instrument and sampling pipelines.

Socket Welding Cap Produce Processing

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 by mould to form cap blanks. 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 and outer profile. Ensure socket depth, bore tolerance and flatness comply with standard drawings.

7. Dimensional Inspection

Fully inspect critical dimensions with calipers, depth 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

Recheck appearance, marking and documents, verify standard, pressure class and specification information.

11. Marking & Packaging

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