High Quality Steel Pipe Flange Cover

Steel pipe flange covers tightly connect the flange cover to the pipe flange with bolts, and the gasket fills the gap between the sealing surfaces to achieve a seal and prevent fluid leakage.

Pipeline Testing: When strength or tightness testing of pipelines cannot be performed simultaneously with connected equipment, flange covers are required at the connection between the equipment and the pipeline to isolate and protect the equipment from the test pressure and media.
Equipment Shutdown and Maintenance: When process pipelines connected outside the boundary area to the boundary area are shut down while the pipelines remain in operation, flange covers are installed at the shut-off valves to prevent material leakage and the ingress of foreign matter. When equipment undergoes regular maintenance, inspection, or switching between units, the equipment involved needs to be isolated, and flange covers can also be installed at the shut-off valves.

Pipeline System Isolation: When a multi-series installation consists of multiple pipelines, the main pipeline from outside the boundary area is divided into several branch pipelines entering each series. Flange covers can be installed at the shut-off valves of each branch pipeline to isolate a specific series. When process pipelines, such as pressurized and displacement gas pipelines, are connected to the equipment, flange covers can also be installed at the shut-off valves to isolate the pipelines from the equipment.
Drain and Sampling System: For low-point drainage of equipment and pipelines, flange covers can be installed after the shut-off valves if process media need to be collected centrally. Exhaust, drain, and sampling pipes on equipment and pipelines should generally also be equipped with flange covers or plugs after the valves, except for materials that are not hazardous to health or explosion-hazardous.
Phased Construction Projects: When constructing a facility in phases, flange covers should be installed at the shut-off valves of interconnected pipelines to facilitate subsequent construction, prevent debris from entering the pipelines, and facilitate the connection of new and existing pipelines.
