Socket Welding Flange

The socket welding flange is a similar sliding flange, unless it has a hole and a counter hole size. The counter hole is matched with the pipe so that the pipe is inserted into the sliding flange similar to the flange. The diameter of the smaller hole is matched with the same pipe with the same ID. The restriction is a built-in hole that stays at the bottom as a shoulder sleeve designed for pipes. This eliminates any flow restrictions when using socket welding flanges.
