copper compound gasket manufacturing

copper compound Gasket manufacturing    Product Description copper compound gasket manufacturing commonly known as oxygen free copper gaskets,Copper Ring Gasket adopts mechanical cutting method and its excellent softness can fill uneven parts on the surface of the flange.Application temperature range, low leakage. 1. copper compound gasket manufacturing performance:
Around use temperature: 500 °C, melting point: 500 °C, hardness: 60 or higher hb before quenching, quenching after 45 hb or less.
2.copper compound gasket manufacturing has good sealing performance, can be made by cold, thermoplastic processing all kinds of semi-finished products and finished products, to ensure that the metal surface and flange sealing surface fit closely.Apply the highest temperature is 800 degrees.Apply pressure 2.0 Mpa - 42 Mpa.  
3.The purpose of copper compound gasket manufacturing annealing is to soften it.When it is necessary to bend was to prevent the fracture and shrinkage cavity (tube), need annealing.If only seal, don't need annealing.When installation, as long as the fastening, can seal.  Detailed Images copper compound gasket manufacturing      copper compound gasket manufacturing copper compound gasket manufacturing   copper compound gasket manufacturing   copper compound gasket manufacturing   copper compound gasket manufacturing    copper compound gasket manufacturing application area   Properties of produc
