Yongnian flat gasket manufacturer, combined sealing gasket manufacturing requirements + 15 years of focus on flat gasket manufacturers
Focusing on the Yongnian flat gasket manufacturer, in order to ensure the sealing reliability of the pressure vessel joint and the combined gasket in the best working condition, the combined gasket must meet the following basic requirements during manufacturing and installation: 1. The surface of the asbestos gasket is quite smooth and clean. Flat and level to ensure the best parallelism of the sealing contact surface during assembly. Generally, the surface unevenness of asbestos gaskets should not be greater than 0.1 mm. 2. The concave-convex sealing groove of the combined sealing gasket is placed at the joint, and the surface roughness of the pressing surface is R. It is 0.3125- 6.25 'm⑴. The human degree is the average deviation of contour arithmetic. 3. The metal tooth-shaped gasket must be made of non-welded and corrosion-resistant materials such as stainless steel by machining. If the tooth-shaped gasket has several phases If the gallery material is tailor-welded and then processed, it must be ensured that the welding seam 4. The tooth shape and size of the metal toothed gasket should be in accordance with West German DIN 2697, and its diameter deviation is ±0.1 5. The asbestos gasket in the combined sealing gasket, The chlorine content in the material is less than 100 PPM, otherwise it will cause corrosion of stainless steel. The best thickness of the asbestos gasket is 0.5mmu. 6. When the combined sealing gasket is installed, it can be installed on the pressing surface and teeth of the concave and convex sealing groove. Apply a non-chlorine sealant (chlorine content less than 1 PPM, such as Van Lili, other sealant grades can be found in the information), or only on the pressing surface, and then 0.5mm thick Asbestos washers are covered on the upper and lower tooth surfaces of the toothed cushions.
