Spectacle Blind Flanges are being used extensively in piping systems for the purposes of flow assurance, isolation, and maintenance work. They are intended to block or allow the flow of liquid by turning between either the open (spacer) or closed (blank) positions. As they are mainly used in the oil & gas, petrochemical, power generation, chemical, and water industries, they are an effective and safer way of inspecting or modifying the pipeline. Spectacle Blind Flanges provide reliable, safe, and simple operation in critical high-pressure and high-temperature industrial and process systems.
