ASME B16.11 A182 F51 Duplex Sockolet Class 3000
ASME B16.11 A182 F51 Duplex Sockolet Class 3000 | High-Strength Socket Weld Forged Fitting
SSM supplies high-quality ASME B16.11 A182 F51 Duplex Sockolets, designed for safe and durable branch connections in high-pressure piping systems. Manufactured from forged duplex stainless steel (UNS S31803), these fittings provide excellent mechanical strength and superior resistance to corrosion and stress cracking, making them ideal for demanding industrial applications.
What Is a Sockolet?
A Sockolet is a type of branch connection fitting used to connect a smaller pipe to a larger run pipe.
It features a socket weld connection for the branch pipe and is welded onto the run pipe (header).
This fitting ensures smooth fluid flow, minimal pressure loss, and strong structural integrity under pressure.
The ASME B16.11 standard defines dimensions, pressure ratings, and tolerances for forged socket weld fittings used in Class 3000, 6000, and 9000 pressure systems.
Material: ASTM A182 F51 (Duplex Stainless Steel)
ASTM A182 F51, also known as Duplex 2205 / UNS S31803, combines the properties of austenitic and ferritic stainless steels.
Key Features:
Excellent resistance to pitting and crevice corrosion.
High yield strength - roughly twice that of 300-series stainless steels.
Outstanding performance in chloride-rich and marine environments.
Stable mechanical properties up to 315°C.
This makes F51 Sockolets ideal for oil & gas, chemical, desalination, and marine applications.
