Product Description

The Matel Pall Ring is a second-generation random packing developed from the classic Raschig ring, and it is also the most representative product among metal random packings. Compared with the traditional Raschig ring, the Matel Pall Ring has several rows of rectangular windows on its ring wall. The inner blades of the windows curve towards the center of the ring, forming a unique inner tongue structure. This seemingly simple improvement has brought about a revolutionary improvement in packing performance.

The design concept of the Matel Pall Ring can be summarized as "internal and external connectivity, three-dimensional mass transfer." The presence of windows allows gas and liquid to flow not only along the outer wall of the ring, but also freely enter and exit the internal space of the ring through the windows. This design completely solves the "wall flow" and "channel flow" problems that are prone to occur with Raschig rings, making both the inner and outer surfaces of the ring effective mass transfer surfaces, and significantly improving the packing utilization rate.

The birth of the Matel Pall Ring marked the transition of random packings from the "first generation" to the "second generation," and established its core position in modern packed towers. Even decades after the advent of the Pall Ring, it remains the most widely used and largest-volume classic product among metal random packings.

Product Feature

I. High Throughput and Strong Processing Capacity
Due to the perforations in the ring wall, the internal space of the Matel Pall Ring is fully utilized. Gas and liquid can freely enter and exit through the perforations, significantly reducing the resistance of the packing layer and substantially increasing the gas-liquid throughput. Compared with Raschig rings of the same specifications, the Matel Pall Ring can increase the processing capacity by more than 50%, making it particularly suitable for applications with high gas-liquid loads.
II. Low Pressure Drop and Significant Energy Savings
The open structure of the Matel Pall Ring allows for smooth gas flow through the packing layer with low local resistance. Under the same processing conditions, the pressure drop of the Matel Pall Ring is much lower than that of the Raschig ring. The thin-walled characteristics of the metallic material further reduce resistance, effectively reducing the energy consumption of the fan or compressor and significantly saving operating costs.
III. High Mass Transfer Efficiency and Excellent Separation
The internal tongue structure of the perforations guides some of the liquid into the interior of the ring, making the liquid distribution more uniform on the surface of the packing particles and avoiding the central dry zone and wall flow phenomena that are common in traditional packings. The gas and liquid phases repeatedly contact and fully transfer mass within the packing layer, significantly improving separation efficiency and achieving the same separation requirements with a relatively low packing layer height.
IV. High Mechanical Strength and Durability
The inherent strength of the metallic material gives the Matel Pall Ring excellent pressure and impact resistance. Compared to plastic or ceramic Pall rings, the Matel Pall Ring can withstand higher packing layer heights and greater gas-liquid impacts. Even in deep bed or high-pressure drop conditions, it is not easily deformed or broken, resulting in a long service life.
V. Diverse Materials, Suitable for Various Corrosive Conditions
AYRTTER Matel Pall Rings can be made from a variety of metallic materials to suit different media environments, ranging from economical carbon steel to corrosion-resistant stainless steel, from high-strength duplex steel to extreme-condition-resistant titanium and Hastelloy, covering almost all corrosive media in the chemical and petrochemical industries.

Manufacturing and Quality
AYRTTER Matel Pall Rings are manufactured using advanced processes and a rigorous quality control system.
Precision stamping process: Utilizing high-precision stamping dies and CNC stamping equipment, the window opening dimensions are accurate, and the inner tongue bending angle is consistent; the ring body has excellent roundness and a flat end face; the edges are smooth and burr-free, reducing air and liquid flow resistance.
Material control: All metal materials are sourced from reputable steel mills, with material certificates provided; each batch of materials undergoes random sampling for chemical composition and mechanical properties testing to ensure compliance with standards.
Quality inspection: Visual inspection ensures no burrs, deformation, or cracks; dimensional inspection checks the ring's outer diameter, height, wall thickness, and window opening dimensions to meet design requirements; material verification ensures the material grade matches the order.
