Spiral wound gasket Fundamentals, Components, Material and color coding. Subscribe -https://goo.gl/9OktFA Website: http://hardhatengineer.com Spiral wound gaskets are fabricated from thin metal strip sandwiched between layered of non-metallic filler. SWG has alternative spiral layers of thin metal sheet and filler material. As these layers are wounded in continues spiral forms, these types of gaskets are known as spiral wound gasket. These gaskets are extremely popular due to the wide variety of available styles and sizes. This YouTube Channel is dedicated to all Engineers working in Oil & Gas and related Energy Business. In this channel, You will learn about Piping, Piping Components such as pipe, fittings, Flanges, Gaskets and many other topics. Check the following web pages to learn various subjects.
