- product description
The advantages of metal-clad gaskets are high strength, non-fragile, strong and strong, but limited rebound force. The flange surface needs to be flat and the tightening force is high to achieve good results (improved, externally applied graphite plate). 201、304、316不锈钢包石墨（耐温650度）包覆垫、包石棉包覆垫，包 陶瓷纤维 （1400度） 包覆垫片等多种形式。 According to different materials, it can be combined into 201, 304, 316 stainless steel coated graphite (temperature-resistant 650 degrees) coated pads, asbestos coated pads, ceramic fiber (1400 degrees) coated pads and other forms.
A3、不锈钢（201、304、316）、铜、铝等 Covering gasket material: A3, stainless steel (201, 304, 316), copper, aluminum, etc.
80%）、石棉（10%）、无石棉、陶瓷纤维（10%）等。 Covering gasket filling material: flexible graphite ( 80%), asbestos (10%), asbestos-free, ceramic fiber (10%), etc.
器 (如 换热器 、反应器 、铸铁法兰、汽缸头、锅炉等 )法兰的密封。 Covering gasket is mainly used for sealing flanges of pressure vessels with large diameters (such as heat exchangers , reactors , cast iron flanges, cylinder heads, boilers, etc. ).
Seals for pumps, valves, pipes and flanges of various equipment. Suitable for medium and low pressure conditions.
1米或非腐蚀用工况可用焊接金属模式；316、316L小型一般禁止焊接。 Welding of stainless steel clad gaskets: Welding metal mode is available for non-corrosive working conditions greater than 1 meter ; welding of 316 and 316L small is generally prohibited.
—耐温650 耐腐蚀；陶瓷纤维—耐温HA1200 ;HZ—1600。 The covering gasket is selected according to the temperature resistance: graphite -temperature 650, corrosion resistance; ceramic fiber-temperature HA1200; HZ-1600.
