Full Coupling Configuration
Socket Weld End
One end accepts compatible pipe into the machined socket for welded installation.
Full-Length Body
The full coupling body provides a straight connection between two sections of pipe.
Opposite Socket Weld End
The second socket accepts the adjoining pipe to complete the straight piping connection.
Construction Details
These 3000# full couplings are manufactured from normalized ASME SA105N forged carbon steel. The forged construction provides the material strength and durability specified for this fitting series, while dimensions conform to ASME B16.11.
Precision-machined socket weld ends help position compatible pipe for fit-up before welding. Once properly installed, the coupling creates a permanent straight connection between the two adjoining pipe sections.

Frequently Asked Questions
What is a 3000# forged steel socket weld full coupling?
It is a forged steel fitting with socket weld connections at both ends designed to join two compatible pipe sections in a straight run.
How is a full coupling different from a half coupling?
A full coupling is designed with connection sockets at both ends for joining two pipe sections, while a half coupling typically provides one socket connection for attachment to another piping component or vessel.
What type of connection does this coupling use?
This fitting uses socket weld connections on both ends.
What material standard applies?
The supplied product information states that forged steel fitting material conforms to ASME SA105N.
Is the material normalized?
Yes. The supplied product information specifies normalized forged carbon steel.
What dimensional standard applies?
Forged steel fitting dimensions conform to ASME B16.11.
What standard applies to forged steel socket weld inserts?
Forged steel socket weld inserts conform to MSS-SP-79.
What standards apply to forged steel unions and outlet fittings?
Forged steel unions conform to MSS-SP-83, while forged steel outlet fittings conform to MSS-SP-97.
