What is the copper flat washer, combined washer? 15 years of washer production experience, the manufacturer tells you
The hardware technicians of the manufacturer focusing on the production of copper flat gaskets said that in order to ensure the sealing reliability of the pressure vessel joint and the combined sealing gasket in a better working condition, the combined sealing gasket must meet the following basic requirements during manufacturing and installation: 1. Asbestos gaskets The surface is quite smooth and flat to ensure good parallelism of the sealed 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 toothed gasket must be made of non-welded and corrosion-resistant materials such as stainless steel by machining. If the toothed gasket has several pieces of phase If the corridor material is tailor-welded and then processed, the weld must be guaranteed. 4. The tooth profile and size of the metal tooth-shaped gasket should be in accordance with West German DIN 2697, with a diameter deviation of ±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 preferred thickness of aero 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’s, other sealant grades can be found in the information), or only on the pressing surface, and then 0.5mm thick Asbestos washers cover the upper and lower tooth surfaces of the tooth-shaped cushion. Hardware, 15 years of focus on copper flat washers, 5,000 square meters production workshop, 3 million punching production capacity per day, imported and national standard raw materials, 16 quality inspections are strictly controlled , Hundreds of precision processing and production equipment, flat washer production accuracy can reach 0.01mm. It can quickly solve the problem of customizing time for flat washers, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose, rest assured!
