PVDF flexiring 16mm (5/8")
Plastic Flexirings is versatile, and plastic Flexirings is an advance on the raschig ring. The plastic Flexirings has similar cylindrical dimensions as plastic raschig ring, but it has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing. Ningbo TCI Plastic Flexirings’s this structure significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.
Ningbo TCI can provide Flexirings in a variety of plastic, such as PP, Polypropylene, PVC, PVDF, HDPE and Glass Filled Polypropylene etc.
Size of plastic Flexirings:
16mm, 25mm, 38mm, 50mm, 76mm, 90mm
Features of plastic Flexirings:
Plastic Flexiringss are suited in low pressure drop, high capacity applications, and raschig rings has range of sizes allows the tower to operate at an optimum efficiency and throughput. With the character high degree of randomness, consistent ratio of free and blocked passages, independent of orientation, plastic Flexirings also has large surface area, the volume ratio augments the rate of liquid film surface renewal to improve mass transfer. Plastic raschig rings’ internal cross-structure of diametrical spars make it mechanically robust and suitable for use in deep packed beds. Plastic Flexirings could also promote highly efficient two-phase contact and distribution with a relatively high liquid hold-up promotes high absorption efficiencies, especially in cases where the reaction rates are slow, uninterrupted and consistent passages for gas and liquid flow.
Application of plastic Flexirings:
Ningbo TCI plastic Flexirings is widely used in absorption, scrubbing, and stripping services, versatile alternative to metal Flexirings, all kind of separation, constant decompress tower plants, compounding ammonia plant, decarbonization plant, separation of ethylbenzene, seperation of isooctane or methylbenzene.
