Quick-opening blind plates are widely used as pressure components in pressure vessels, pressure pipelines, and related equipment, enabling rapid opening for maintenance, internal component replacement, and repairs. In the natural gas industry, they are commonly applied to devices requiring intermittent operation, such as gas filters, gas filter separators, and pig launcher/receiver units. They can replace pressure vessel manholes, quick-opening doors for pigging systems, filter(separator) units, and vulcanizing tanks.
