NINGBO SHINE SEALING MATERIAL CO.,LTD. provides you with high-quality Standard Spiral Wound Gasket products!
At present, metal spiral wound gaskets, especially graphite spiral wound gaskets, are most commonly used in oil refineries, accounting for more than 80% of commonly used gaskets. Our Standard Spiral Wound Gasket product is your perfect choice!
The selection of metal spiral wound gaskets is mainly determined by the use environment of the gasket, especially the corrosiveness and cleanliness of the sealed medium. At present, the commonly used metal belts in my country are 0Crl8Ni9, 0Crl7Nil2Mo2, 00Crl7Nil4Mo2Ti; non-metallic belts are flexible graphite, polytetrafluoroethylene or special asbestos; the outer ring material is generally carbon steel; the inner ring material is mostly the same as the metal belt material.
Metal wound gaskets are divided into basic type, inner ring type, outer ring type, inner and outer ring type according to the structure. The form of the metal wound gasket needs to match the form of the flange sealing surface, and the common matching relationship is shown below.
