1. Pall Ring Product Overview

The 76mm polypropylene plastic pall ring is a ring packing made of polypropylene (PP) material, designed for tower equipment in the chemical, environmental protection and energy industries. Its core structure is a cylindrical ring body with windows and internal ribs evenly distributed on the surface, forming unique fluid mechanics characteristics, which significantly improves the gas-liquid mass transfer efficiency.

2. Pall Ring Performance Advantages

Plastic pall Ring Efficient Mass Transfer

The window hole and internal rib design optimizes the gas-liquid contact, and the mass transfer efficiency is increased by more than 20% compared with the traditional Raschig ring.

The low pressure drop characteristics (40-50mmH₂O) reduce energy consumption and are suitable for long-term operation of large towers.

Plastic Pall Ring Anti-blocking Ability

The high void ratio (92%) reduces solid particle deposition and extends the service life of the packing.

Plastic pall Ring Operation Flexibility

It can operate stably within the load range of 50%-120% to adapt to process fluctuations.

3. pall ring selection and purchasing suggestions

Plastic pall ring specification matching

The 76mm specification is suitable for towers with a diameter of ≥800mm. It is recommended to use the φ25-50mm specification for small-sized towers.

Plastic pall ring material selection

PP material is selected for conventional working conditions; PVDF material can be selected for high temperature (>100℃) or strong corrosive media.
