Pall rings are widely known as an innovation coming from Raschig Ring that can be used in various applications, mainly involves gas and liquid transfers. Its walls is intentionally designed to be open geometrically to enable lower pressure drop with greater capacity than on Raschig ring design which is just a standard cylindrical ring.
This pall rings media further maintains uniform distribution and resists wall-channelling inclination. Pall ring suppliers positively push the product's potency to consumers since it has been designed with enough number of contours and crevices to carefully control the liquid and gas transfer rates.
Pall rings packing shows its interior and exterior surface contact which is beneficial to resist plugging, nesting, and fouling all along in with the distribution of liquid and gas. Pall rings function with versatility, high resistance to fouling, high temperature, and can be easily soaked.
With complete assurance, this pall ring packing is of high mechanical strength making it sturdy in accordance to the pall ring material capacity. Breakage is of minimal occurrence which makes the pall ring fits best on deeper beds.
Pall ring manufacturers ensure a better distribution of liquid or gas along with a good mass transfer efficiency. Equipped with both expertise and experience, this pall ring has been innovated to meet every consumer requirements.
Stainless steel pall rings
It (also named as ss pall rings) performs high loading and low pressure drop together with an efficient high mass transfer and better liquid/gas distribution. The stainless material brings edge to resist against corrosion.
Plastic pall rings
It is offered in a variety of plastics such as PVDF, Polypropylene, HDPE, PVC, and Glass Filled Polypropylene. Commonly available in natural color but their are manufacturers who accepts customized orders.
Metal pall ring
Among all pall rings made up of different materials, this metal pall ring is the one that is mechanically sturdy with high resistance to high temperature and fouling.
Polypropylene pall rings
This is the most common pall ring packing made up of plastic. It is also named pp pall rings. It can resist to more than 100 degrees celsius but has a lower thermal deformation temperature.
Ceramic pall rings
Ceramic pall rings has a strong resistance against alkali and high temperature.

Pall ring sizes are commonly available in: 16mm, 25mm, 38mm, 50mm, 75mm.
Its appears mostly in black or white.
It ranges from 39mm to 44mm long.
All appears cylindrical with punched holes on its walls.
Pall rings are available in various materials such as: stainless steel, plastic, metal, polypropylene, ceramic.
Pall ring has a capacity versus pressure drop
It has a high loading and low pressure drop
It has a good distribution on either gas or liquid
Its mass transfer efficiency is high
It is versatile
When it comes to fouling, it has high resistance
It provides lesser probability of breakage
It is recommended for deeper beds
It has been intended that Pall ring can be used in almost all kinds of separation, constant decompress plants, absorb plants, compounding ammonia plant, desulfurization, decarbonization, separation of isooctane/methylbenzene, separation of ethylbenzene, aeration, absorption, desorption, degassing, stripping, distillation, extraction, heat recovery and atmospheric pressure's separation and absorption, it is when the lower pressure drop happens at a critical level.
Furthermore, it is also used for quench towers, direct contact cooling, steam stripping, reaction columns, distillation columns, and tower packing. Pall ring has been designed in different sizes as to optimise its capability and efficiency of performance on various application requirements.

Pall rings can be used for mass transfer operations that often includes stripping, gas scrubbing, de-aeration, biological filtration, degassing, and mechanical filtration. With its variety of applications, Pallring did not fail in curtailing the number of crevices and contours making the liquid to hold-up.
Pall ring design allows lower pressure drop and greater capacity compared to standard cylindrical rings like in Raschig rings. The protrusions bending inward and its open cylinder wal did all the magic of its best performance.
As considered to be the second generation of random packing, its use is to mainly allow the flow of gas or liquid to happen fully in the ring inner surface. From Raschig purely designed cylindrical ring, pall ring intend to open one or two layers of geometrically designed holes in its sidewall in the inward bending direction to satisfy its engineering purpose.
Pall rings color appears mostly in black or white but for plastic and stainless pall rings, it as available plainly in natural colors.
Sizes of pall rings are commonly within the range of 16mm to 75mm.
Different suppliers may be available in the market for pall ring distribution but with us, we bring forth the integrity of delivering the best performance of pall rings available in different kinds of materials. For both high in capacity and for the purpose of low-pressure drop, our engineers did not fail to craft what every consumer needs from us.
This is the main reason why our produced pall rings are highly recommended to its high degree of randomness offering a large surface area to enhance the volume ratio and the rate of liquid to effectively improve the mass transfer.
With the attempt to increase the complete aspect of packing, by reducing the volume used up by the ring packing medium, it also provide an increased count of edges to disrupt the flow. Instead of having the old solid-walled tube, the pall ring is modeled to resemble an open basket structure composed of thin bars.
With the design of both radial structure of cross bars and a tube, independent on its material being used, performs efficiently as anticipated.
For the advancement and improvement of uses, pall rings offers a great deal of performance. Different suppliers may be available in the market offering a wide variety of pall rings from the material being used to the difference in size, the need to choose which one is manufactured efficiently for long term use is crucial. A research and comparison in between product should be done prior to purchasing and making any order. This is for the purpose of choosing for the best required product based according to its intended purpose. Above all, durability and performance is what every consumer should always consider.
