Construction Details
The SCI S3716U is a heavy-pattern 150# cast stainless steel union manufactured in 316 stainless steel. The stainless steel castings conform to ASTM A351.
Socket-weld connections provide permanent welded attachment to the adjoining pipe, while the center union connection allows the assembled piping sections to be separated when maintenance or equipment access is required.
This configuration is useful where a stainless steel welded piping system requires a planned disconnection point without cutting the adjoining pipe.

The union is manufactured from cast 316 stainless steel.
What material standard applies to the casting?
The 316 stainless steel castings conform to ASTM A351.
What connections does the union use?
The union uses socket-weld connections for attachment to compatible adjoining pipe.
What is the purpose of a socket-weld union?
It creates an in-line connection that can be separated at the union without cutting the adjoining welded pipe.
How is a union different from a full coupling?
A union can be separated at its center connection, while a full coupling creates a continuous permanent connection between two pipe sections.
Where is this union commonly used?
It is suited to compatible industrial, chemical, petroleum transfer, process piping, and equipment connection applications.
What should I confirm before ordering?
Confirm 316 stainless construction, the required fitting class, socket-weld connections, and compatibility with the intended piping system.
