This 3/4 socket weld flange is 316 Stainless Steel with a raised face face in 150#. TheyÕre often chosen for smaller lines where a tidy weld setup matters and alignment is critical. 316 provides extra protection compared to 304 in many real-world conditions. Use this socket weld flange when you want a familiar, bolt-together connection you can service later without drama. At PLYET Industrial Supply, we stock connection hardware like this because downtime isnÕt an option. Order it when youÕre ready, and if you want a second set of eyes on fitment, just reach out to our team.
