Liaocheng flat gasket manufacturer, what is a combined sealing gasket + 15 years of gasket production experience manufacturer

The technical personnel of the Liaocheng flat gasket manufacturer said that 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 equivalent. Smooth and neat 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 the contour arithmetic. 3. The metal tooth-shaped gasket must be made of non-welded, corrosion-resistant materials such as stainless steel by machining. If the tooth-shaped gasket has several pieces of phase If the corridor material is tailor-welded and then processed, the weld must be guaranteed. 4. The tooth shape and size of the metal toothed 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 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’s, 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. Hardware, 15 years of focus on Liaocheng flat washer manufacturer, 5000 square meters production workshop, daily production capacity of 3 million strokes, imported and national standard raw materials, 16 quality inspection layers are strict Check, hundreds of precision processing and production equipment, flat washer production accuracy can reach 0.01mm. It can quickly solve the problem of customizing time of flat washer, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose, rest assured!
