Plastic Ralu Ring

Size: 15mm, 25mm, 38mm, 50mm, 90mm, 125mm

Plastic Ralu Ring is an improved pall ring. The mainly improvement is increase two ends turn-ups and wall's thickness. At an unchanged separation efficiency, the bed height reduced while decreasing the pressure drop.


Plastic lalu ring packing is to keep the ratio of height to diameter of pall ring equal to 1 on the basis of increasing the taper flanging, increasing distribution points inside, so that the vapor liquid mass transfer is even, while the surface renewal is accelerated. Plastic laru ring packing has the characteristics of low pressure drop, large flux and high efficiency. The product has lower pressure drop and higher mass transfer efficiency than the similar size pall ring, and has better liquid distribution in the packing layer. The melting point of plastic laru ring is 164-170ºC, and it can be sterilized at a temperature above 100ºC. In the absence of external forces, 150ºC does not deform, the stress relaxation at 90ºC is good, its embrittlement temperature is -35ºC; Due to its high crystallinity and neat structure, polypropylene has excellent mechanical properties and outstanding bending strength. For example, PP injection molding -- body movable hinge can withstand 70 million times of folding and bending without damage marks, and has good heat resistance. The product chemical stability is very good, in addition to can be concentrated sulfuric acid and concentrated nitric acid erosion, to other kinds of chemical reagents are relatively stable, at the same time, its chemical stability with the increase of crystallinity is also improved.

Functional Characteristics:
1.the plastic lalu ring is based on the pall ring, which makes the flux increase and the pressure drop decrease.

2.plastic lalu ring is made of high temperature and corrosion resistant materials injection molding, the main materials include: PP, PE, RPP, PVC, CPVC and PVDF.

3.plastic lalu ring has the advantages of large voidage, reduced pressure, low mass transfer unit height, high flooding point, adequate gas-liquid contact, small specific gravity, high mass transfer efficiency. The main temperature of plastic bulk packing is 60-280 c.

4.suitable for all kinds of separation, absorption, desorption device, constant pressure reduction device, synthetic amine decarbonization, desulfurization system, ethylbenzene separation, isooctane, toluene separation.
