What is Style CG Spiral Wound Gasket?
Style CG spiral wound gasket utilizes an external ring that accurately centers the gasket on flange faces, and provides radial strength to prevent gasket blowout and a compression stop. The CG spiral wound gasket is a good general purpose gasket and is suitable for use with flat-face and raised-face flanges. Style CG spiral wound gasket is a general purpose gasket suitable for use with flat face and raised face flanges up to and inclusive of class 2500. Class 900 and above an internal ring is recommended.
Gaskets for standard flanges are 0.175" (4.5mm) thick, fitted with 0.125" (3.2mm) thick solid metal rings. Unless otherwise stated.
What is the Application of Style CG Spiral Wound Gasket?
Style CG spiral wound gaskets are precision engineered for flanged joints, heat exchangers, boiler handholes, manholes and high temperature applications, and offer resistance to corrosive and toxic elements.
What is the difference between CG and CGI Spiral Wound Gasket?
Style CG spiral wound gaskets are suitable for use in mild to moderate service conditions. Style CGI spiral wound gasket consists of a winding ring, inner and outer ring, and CG type gasket just consists of a winding ring and an outer ring.
