Full plate flange pad: Compared with ordinary flat flange pads, the safety and stability of the pipe network are guaranteed to the greatest extent. From the perspective of reducing production and sales gap and safe water supply, the role of flange pad is very important. The complete water-stop flange pad is a new type of flange pad with a unique structure developed based on the existing glossy flange pad. This product has the following advantages:

1. A suitable amount of concentric water stop lines are evenly distributed on the sealing surfaces on both sides. Each concentric water stop line has an independent sealing effect, strong compressive resistance, and it also has a good sealing effect when installed on flanges with concave and convex surfaces, rough processing or even corroded surfaces.

2. When the water pressure is too high, ordinary flat flange gaskets are prone to displacement and even directly flush out from the bolt holes. After using this kind of full-disk flange gasket, the displacement of the flange gasket is only between the very small gap between the bolt and the hole, ensuring the safety and stability of the pipeline to the greatest extent.

3. Due to the use of concentric spherical line design, the optimal sealing effect can be achieved with the minimum fastening force when used, and can effectively reduce the influence of water pressure impact force, thereby achieving an effective and long-term sealing effect.

4. An accurate installation and positioning device is designed, which only needs one person to operate during installation, thereby improving work efficiency and saving installation costs.
