  • Ürün Detayı

A weld neck flange is a type of flange used for connecting pipelines in a variety of industries, including the oil and gas, kimyasal, ve petrokimya endüstrileri. As the name suggests, the weld neck flange is welded to the end of a pipe, Güvenli ve sızıntıya dayanıklı bir bağlantı sağlamak.

Stainless steel weld neck flanges are widely used due to their excellent corrosion resistance and durability, making them ideal for use in harsh environments such as offshore platforms, chemical processing plants, and gas refineries. These flanges are made of high-grade stainless steel such as 304, 316, or 321, and are available in a range of sizes, pressure ratings, and configurations to suit different applications.

One of the main advantages of weld neck flanges is that they provide a strong and stable connection that can withstand high pressures, temperatures, and vibrations. The tapered neck design of the flange helps to reduce stress concentration at the base of the welding joint, making it less susceptible to cracking or failure. Ek olarak, the raised face of the flange provides a smooth and even sealing surface, reducing the risk of leaks or contamination.

Etraflı, stainless steel weld neck flanges are a reliable and long-lasting solution for joining pipelines in high-pressure and high-temperature applications. Their resistance to corrosion, chemical attack, and mechanical stress makes them an excellent choice for use in harsh environments, where safety and reliability are crucial.
