Industrial use products work on only specific requirements. Spiral wound gaskets are one such mechanical equipment with a unique shape to bear high pressure. The primary function of gaskets is to seal irregular faces of the flanges. A flange joint comprises separate but interrelated components,i.e., the flanges, the gaskets, and the bolting. The formation of gaskets is of flat material, which keeps up with the requisite characteristics.
General characteristics of spiral wound gaskets
Most of the gaskets tend to be inexpensive and readily available for general use. Gaskets usually prove the effectiveness by withstanding high compressive loads. Specific tests also confirm the load limit for particular gasket material. The suitability of the round spiral gaskets depends on the temperature and pressure of the existing fluid. It also depends on the corrosive nature of the application or medium. Flange configuration also plays a vital role as a determining factor for choosing such a product.
Spiral wound gaskets embody various materials such as paper or rubber, or metal. Teflon or PTFE (Polytetrafluoroethylene) and other plastic polymers are also the conventional raw components for gaskets. Consumers choose specific materials for the distinct outstanding characteristics it possesses. For instance, the mechanical properties of steel deliver satisfactory results, and graphite is resistant to heat or temperature. High-pressure steam systems utilize asbestos. Practically, many buyers avoid the usage of asbestos gaskets due to the health effects of asbestos exposure.
General identification of spiral wound gaskets
The spiral wound gaskets have a specific shape that helps in its identification. The outer or center ring lines within the inner ring, and finally, there is the layer of spiral winding. The center ring's outside edge color showcases the composition of both the filler materials and the winding materials. Spiral wound gaskets are semi-metallic, and the support rings make it more adaptable for corrosive or flammable fluids. The formation of the ideal gaskets is via V-shape metallic strips and safe non-metallic fillers. These are suitable for both flat or raised flange faces.
The handling of adverse conditions
Spiral wound gaskets confine themselves under the category of composite gaskets and are most outstanding in this range. It proves much more cost-effective than metal ones. Most of these products function with or without the application of the inner ring. However, the wound gaskets with inner rings add support to the winding material. Yellow stainless steel bands with gray stripes specifically utilize themselves with thermal cycling. Type HE gaskets are applicable for heat exchangers predominantly apt for male or female pipe flanges.
