PP Flange is a flange connector made of polypropylene. Flange connection is a connection method commonly used in pipeline systems. It connects two pipes or pipes to equipment through bolts to form a sealed connection. PP Flange is widely used in the industrial field due to its excellent performance characteristics.
PP fiber backing ring
A new PP reinforced, full plastic backing ring flange, It’s a new corrosion-free, full plastic, fiber-reinforced PP that is lightweight, reliable, and with a long life span. The size will go up to 400mm.
It is not only for HDPE piping systems but also for PPH, PPR ABS UPVC, etc.
PP Flange is a part that connects pipes to each other and is connected to the pipe end. In pipeline engineering, flanges are mainly used for pipe connection. Flanges of different pressures have different thicknesses, corresponding numbers of screw holes, screw hole sizes are also different, and different bolts are used.
1. PP Flange has excellent corrosion resistance. Polypropylene is a chemically inert material that can remain stable in many strong acid, strong alkali, and organic solvent environments. Therefore, it is very suitable for pipeline systems in the fields of chemical, pharmaceutical, food, etc., and can effectively prevent corrosion in pipeline systems.
2. PP Flange has good high-temperature resistance. Its operating temperature range is usually between 0 and 90, and it can withstand a certain high-temperature environment. This makes it widely used in some special industries such as petrochemicals, metallurgy, and other fields.
3. It has excellent sealing performance. During installation, use appropriate sealing gaskets to connect the two flanges to ensure complete sealing of the joints. This can not only prevent leakage of the medium but also effectively prevent external dust and impurities from entering the pipeline system.
4. The advantages of being lightweight, having a simple structure and being easy to install. Compared with flange connectors such as Steel Flanges and Ductile Iron Backing Ring, the PP Flange is lighter and easier to carry and install. At the same time, its structural design is relatively simple, and no hardware processing is required, making installation more convenient.
