Schweißflansche

Schweißflansche, also known as welding flanges, are connecting pieces used in piping systems. They are typically circular and are designed to be welded to a pipe. The other end of the flange usually has bolt holes, allowing it to be bolted to another flange, a valve, a pump, or other equipment, creating a sealed connection. This method of joining is common in industries where high pressure or temperature resistance is required, such as in chemical processing, oil and gas, and power generation.

There are several types of welding flanges, distinguished by their design and intended application. Weld neck flanges are characterized by a tapered hub that is butt-welded to the pipe, providing a strong and durable connection. Slip-on flanges are slid over the pipe and then welded both internally and externally. Lap joint flanges are used with stub ends, where the flange itself does not come into direct contact with the fluid. Socket weld flanges are designed for smaller bore piping and involve inserting the pipe into a socket before welding. Orifice flanges are specifically designed to accommodate orifice plates for flow measurement.

The selection of a specific type of welding flange depends on factors such as the operating pressure, temperature, the type of fluid being transported, and the required sealing integrity. Material selection is also crucial, with common materials including carbon steel, stainless steel, and various alloys to suit corrosive or high-temperature environments. Proper welding procedures are essential for ensuring the integrity and leak-proof performance of the assembled piping system.
