As its name suggests, the 8-letter blind plate is shaped like the number “8” and consists of two round metal plates connected by a short rod in the center, which presents a unique three-dimensional structure as a whole. The two circular plates, one is a solid blind plate without any holes, used to completely cut off the pipeline access; the other is a concentric plate with holes, the number and size of the holes match the diameter of the connected pipeline and the designed flow rate, which can realize the normal flow of the pipeline. This clever design makes the 8 word blind plate can be in different working conditions under the demand for flexible switching pipe through the state.

Common materials include carbon steel, stainless steel and alloy steel. Carbon steel material is relatively low-cost, with a certain degree of strength, suitable for some of the corrosive requirements are not high, the working conditions of the more conventional industrial piping, such as ordinary steam heating pipeline, part of the water supply and drainage pipelines. Stainless steel materials, such as 304, 316 stainless steel, with excellent corrosion resistance, commonly used in food processing, pharmaceuticals, fine chemicals and other sanitary conditions and corrosion resistance requirements of the industry piping system, can effectively prevent the pipeline medium contamination of the product or by the product corrosion. Alloy steel material with its high strength, heat resistance and special wear-resistant performance, in the petrochemical industry, natural gas mining and transportation and other high temperature and high pressure and complex media in harsh environments, to ensure that the 8 word blind stable and reliable in harsh working conditions.
