Spiral Wound Gasket Spiral Wound Gasket is made of alternate piles of V-preformed hoop and soft filler that are tightly and spirally wound together. According to the need of the mating flange, the gasket is provided with an outer ring, an inner ring or both outer and inner rings. The outer ring serves as a compression stop, anti-blowout device, which properly centers the gasket on the flange. The inner ring acts as a compression stop and is used to fill the annular space between the flange bores and the gasket inside diameter to minimize trubulence of process fluids and erosion of flanges faces. The spiral wound outer or inner rings are used primarily as reinforcement and are chosen instead of a solid metal ring, because of lower costs or because of limited space when the use of a solid metal ring would be prohibited due to the difficulty in fabrication or usage. ZW spiral wound gaskets can be manufactured in accordance with all relevant gasket standards to suit various flange designation such as ASME/ANSI B16.5, API 605 (ASME B16.47 Series B), MSS SP-44 (ASME B16.47 Series A), AWWA, CNS, DIN and JIS. The size is available from OD 1/2” to 5000mm. Please note the gaskets for non-standard flanges or heat exchanger with partitions are also readily available. Low stress spiral wound gasket could replace normal non-metallic gasket in ANSI 150#/300# Flange under lower torque, about only 60% of traditional spiral wound gasket. ® ●Style Soft Filler Material Style Profile
