Description
Gaskets are used for sealing flange connections in pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, handholes, and other equipment in industries such as petroleum, chemical, metallurgy, power, shipbuilding, and machinery. The dataset includes major raw and auxiliary materials, energy inputs, and waste outputs from the production process; however, infrastructure such as production equipment and factory construction are excluded from the system boundary. The life cycle inventory is compiled from data derived from multiple sources. The manufacturing process of gaskets includes raw material preparation, powder production, V-shaped metal strip processing, flexible graphite production, spiral wound gasket winding, quality inspection, and packaging.
Activity Description
The production activities of the product include raw material procurement, powder preparation, V-shaped metal strip processing, flexible graphite production, winding gasket manufacturing, quality inspection, packaging and other processes.
Process Description
The gasket is manufactured by spirally winding a "V"-shaped metal strip and flexible graphite alternately, then assembling an outer ring onto the gasket body (a metal-wound gasket body with an inner ring). This product is suitable for sealing flange connections in pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, handholes, and similar applications in industries such as petroleum, chemical, metallurgy, power, shipbuilding, and machinery.
