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 cross is a special pipe fitting for fourway pipeline connection to realize flow diversion and confluence in piping systems, with socket welding connection and made of nickel alloy. It is available in various port configurations, and the corresponding port combinations can be selected according to pipeline design requirements to flexibly adapt to different pipeline branch layouts.
During installation, the matched pipes are inserted into the sockets of each port of the cross one by one, and welded after alignment and positioning. The socket structure provides positioning limit, which makes centering easy. The welding zone avoids the main stress area of the fitting body, so the weld works under favorable stress conditions with high connection strength and reliable sealing. It has a compact structure and is suitable for working conditions with limited installation space.
The fitting features stable and lasting pressure resistance and outstanding corrosion resistance, capable of longterm continuous and stable operation under complex hightemperature and heavily corrosive service conditions. Manufactured in strict accordance with relevant industrial specifications for pipe fittings, it has a wide range of specifications compatible with various nominal diameters and different high pressure classes with stable quality control. It is widely adopted in process piping systems for corrosive media in chemical, oil & gas, new energy and other industries.








1. Incoming Raw Material Inspection
Incoming inspection of nickel alloy raw materials. Check appearance, dimensions and supporting quality documents to confirm compliance with technical requirements.
