Blind flange connections are the most common

         Blind flange connections are the most common and common way of connecting a variety of containers and process pipelines. Taking into account the requirements of the production process or to consider the manufacture, transportation, installation and maintenance of the convenience of the container and the process of pipe connections often use removable structure that is welded flange connection, which has good joint strength and tightness, and the size The range is relatively wide; therefore,BS4504 Forged Stainless Steel Blind Flange connection is widely used in vacuum salt enterprises because the container and the medium in the pipeline is the sodium sulfide solution (ie brine). Has a relatively strong corrosive. Although the flange has a high strength and good plasticity and cut, but its poor corrosion resistance, the general use of time in a month after a large area of corrosion will occur after six months there will be a large area Perforation. Causes the media to leak. If the use of blind flange.
