1/2 in Socket Weld Union
This 1/2 in socket weld union joins two pipes of matching size in a straight line. It is made from 304 stainless steel and rated for Class 3000 pressure service. The fitting suits installers who need a corrosion-resistant joint for water, oil or gas lines in industrial or commercial piping systems. It is not intended for flare, compression or threaded connections that require a different end preparation.
Class 3000 pressure rating
The Class 3000 designation means the union is designed to hold its seal under sustained system pressure without permanent deformation. The 304 stainless body resists scaling and chemical attack during long-term exposure to hot or aggressive fluids. Repeated thermal cycling will not loosen the socket weld if the joint is correctly fused. The fitting does not contain a gasket or O-ring that could degrade and require periodic replacement.
Socket weld installation
Installation requires a socket weld machine or qualified welder to fuse the pipe into each female socket end. The pipe must be cut square, deburred and inserted to the full socket depth before welding. Misalignment or incomplete fusion are the most common causes of leaks on this type of union. The finished weld should be inspected visually and, where code requires, by non-destructive testing before the system is pressurised.

Questions about this item
Does the 304 stainless steel union get hot or create noise when used continuously in a Class 3000 plumbing system?
The fitting is a passive component with no moving parts or power draw, so it generates no noise and no heat of its own during all‑day operation.
What pipe size and schedule must I already have to socket‑weld this 1/2 in union?
You need 1/2 inch nominal pipe with a schedule that matches the Class 3000 pressure rating for a proper socket weld joint.
Will the 304 stainless steel union join cleanly to older carbon‑steel pipe already in place?
Direct socket welding of 304 stainless to carbon steel is not standard practice; a transition piece or appropriate welding procedure is required.
