Stainless steel socket flanges are installed during pipeline construction and connected to another pipeline through bolts to achieve a tight connection of the pipeline. This type of flange is usually made of stainless steel and has high corrosion resistance and high temperature resistance. Its structure generally includes flanges, gaskets, bolts and other components.
Stainless steel socket flanges are widely used in pipeline connections in various industries, especially in places where high requirements are placed on pipeline connectors. For example, in the petrochemical industry, where the pipelines are long and the media are complex, stainless steel socket flanges are the first choice due to their good corrosion resistance and high temperature resistance. In addition, in the food processing and pharmaceutical industries, the use of stainless steel socket flanges can also ensure the hygiene and safety of the pipelines.

Characteristics of stainless steel socket weld flanges
Good corrosion resistance: Stainless steel itself has good corrosion resistance. After being processed into socket weld flanges, its corrosion resistance is stronger and it is suitable for pipelines for various chemical media.
Excellent high temperature resistance: Stainless steel forged flanges can withstand high temperature environments and can usually be used at temperatures below 400°C, so they are widely used in high temperature process flows.
Reliable connection performance: Connections are made by threading or welding, and the connection is firm and reliable, without air leakage or water leakage, ensuring the safety of pipeline operation.
Easy installation: The installation of socket weld flanges is relatively simple. You only need to insert the flange into the pipeline and fasten the bolts without using complex tools and equipment.
Wide applicability: Socket weld flanges can be used in multiple industries such as petroleum, chemical, natural gas, pharmaceuticals, food, metallurgy, shipbuilding, etc., to meet the pipeline connection needs in different environments.
