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.

SW Olet Introduction

Socket Weld Branch Outlet, also known as Sockolet, is an integrally forged selfreinforced branch fitting for piping systems, manufactured from nickel alloy. It features a contoured saddle base for close fitting and welding onto the outer surface of the main pipe. The outlet end is machined with a standard socket bore, into which the branch pipe end is inserted and fixed by socket fillet weld.


It is applied to create branch takeoffs from the main pipe, replacing the traditional combination of tee and reinforcing pad. The integrated reinforcement structure effectively distributes stress around the pipe opening. With a compact shape, it is mainly suitable for smallbore branch connections. The socket weld connection is easy to assemble and less demanding for on-site alignment, ideal for instrument connections, sampling lines and other small branch services.


This fitting complies with MSS SP97, GB/T 19326, ASME B16.11 standards, available in pressure classes 3000, 6000 and 9000. It serves hightemperature, highpressure and corrosive working conditions, and is widely used in oil & gas, chemical plants and power station process piping.

SW Olet Produce Processing

1.Raw Material Inspection: Verify nickel alloy billets, carry out visual check and non-destructive test to eliminate internal defects.

2.Cutting: Cut billets according to drawing specifications, reserve proper allowance for forging and machining.

3.Heating and Forging: Heat billets to forging temperature, hot forge with dies to form the basic profile and socket cavity.

4.Heat Treatment: Perform heat treatment in accordance with process specification to relieve forging residual stress and stabilize mechanical properties.

5.Shot Blasting: Clean the forging surface by shot blasting to remove scale and oxide contaminants.

6.Rough Machining: Rough machine saddle surface, outer profile and socket bore on CNC machines, leave finish machining allowance.

7.Finish Machining: Precisely machine saddle contour, socket depth and inner bore to meet tolerance requirements of relevant standards.

8.Marking: Stamp traceability information including size, pressure class, heat number and applicable standard on the fitting body.

9.Final Inspection: Recheck all dimensions and appearance, conduct PT, UT or other NDT as required.

10.Surface Protection: Clean grease and impurities on surface, apply protective treatment if necessary.

11.Packaging and Warehousing: Pack qualified products properly and register into warehouse for delivery.
