Winding gaskets mainly include metal winding gaskets, graphite winding gaskets, graphite-metal winding gaskets, metal-graphite winding gaskets, inner and outer ring winding gaskets, metal-asbestos winding gaskets, metal-PTFE winding gaskets, etc. Spiral wound gaskets mainly include metal spiral wound gaskets, graphite spiral wound gaskets (repeated), basic metal spiral wound gaskets, and inner and outer spiral wound gaskets.
Metal-asbestos spiral wound gaskets, PTFE-metal spiral wound gaskets, etc., are also available. Spiral wound gaskets are made by continuously winding "V"-shaped (or "W"-shaped) metal strips and non-metal strips in alternating layers, with the metal strips welded and fixed at the beginning and end. They are characterized by a wide range of applicable conditions, including heat resistance, high-pressure resistance, and suitability for low-temperature or vacuum applications.
By changing the material combination of the gasket, various chemical corrosion issues can be addressed, and they have strong stress compensation capabilities. The sealing performance is stable and reliable, even under frequent temperature and pressure fluctuations. The sealing performance is excellent. The flange surface in contact with the gasket does not require high precision, making installation convenient and requiring low preload pressure for the gasket.
Due to the variety of sealing gaskets and their suitability for different locations in various industrial settings, we can recommend corresponding gasket models, such as metal spiral wound gaskets, copper gaskets, graphite gaskets, PTFE gaskets, etc. Please provide various parameters to facilitate the selection of cost-effective products that meet your needs.
When selecting any type of sealing gasket, especially metal spiral wound gaskets in harsh application environments, to ensure long-term effective sealing, the following eight key factors must be considered: sealing system materials, recommended temperature and pressure ratings for the gasket during operation, tight sealing between the gasket and the flange contact surface after bolt tightening to ensure sealing.
