Flat weld flanges are flanges that are welded directly to equipment or piping by fillet welds. The structure is simple and the processing is convenient. The force characteristics are between the integral flange and the looper flange. The flat weld flange is divided into a plate type flat weld flange and a neck flat weld. The flat weld flange has low cost and short production cycle, which is the most commonly used. A flange type that is widely used in various fluid lines.

Flat welding flange has a beautiful shape and a smooth and smooth appearance. It is mainly used for the connection of carbon steel pipes, and its nominal pressure does not exceed 2.5 MPa.

Flat welding flange is resistant to acid and alkali, anti-corrosion, and strong in texture. It is made of i-oxygen furnace, and the whole forging or forging product is forged and formed by high-precision CNC lathe turning and CNC rocker drilling.

The joint method of the flat welding flange includes single-sided welding and double-sided nut connection. When welding, only one-side welding is required, and the inner mouth of the welded pipe and the flange connection is not required, and is generally used for low- and medium-pressure pipes.

The sealing surface of the flat welding flange can be made into three types: smooth, concave and convex and grooved. In the meantime, the smooth flanges are the most widely used, and are often used in applications where the medium conditions are relatively flat, such as low pressure non-purified compressed air and low pressure circulating water.
