Welding of valves and pipes
Thread Content
May I ask if the valves of A182-F11 can be welded to 321 stainless steel seamless pipe fittings?
There should be no problem with this; it can be welded. However, it is best to weld pipes made of the same material, connecting the ends with flanges, thereby avoiding welding of dissimilar steels.
Is it a butt-welded valve? For butt-welded valves, it is best not to weld them directly to the pipes; welding different types of steel can lead to corrosion at the welded area. Flange valves are easier to handle; for the flanges that pair with the valve, A182Gr.F11 flanges will suffice.
Logically, there should be no problem and welding is possible; however, many people use rods of the same material for welding
In 2016, I was involved in welding F316 and monel
Your valve is of the welded type; different materials require different welding methods, and corresponding electrodes and welding wires must be used for processing
Sure, I’ve seen people do welding
