PLATE FLAT WELDED STEEL PIPE FLANGE

Flat weld steel flange, also known as plate flange or slip-on flange, is widely used for connecting pipes, valves, pumps and other equipment in industrial piping systems. It features a flat circular disc with a central bore and evenly spaced bolt holes, welded to the pipe neck for a permanent and leak-proof joint.
