Metal packing is mainly divided into two categories: random packing and structured packing, specifically including:

1. Random packing: Raschig rings, Pall rings, Cascade mini rings, Saddle rings, Conjugate rings, etc.

2. Structured packing: Wire mesh corrugated packing, perforated plate corrugated packing, rolled perforated corrugated packing.


The usage method of metal tower packing:

1. Treatment of packing before installation

There is a thin oil layer on the surface of the new packing. This oil layer may be formed by lubricating the metal packing with lubricating oil during the processing, or it may be anti-rust oil added to prevent the carbon steel packing from being corroded during transportation and storage. The presence of this layer of oil is not very friendly to some usage environments. For instance, in an air separation system, when the oil layer is washed off and coexists with liquid oxygen, it may cause an explosion. For aqueous solution systems, this layer of oil can hinder the formation of the liquid film. For some alkaline systems, it can also cause the solution to foam. Therefore, it should be cleaned with a solvent before use.

It should be noted that if the carbon steel packing is not in use for the time being, it should be stored in a dry and sealed place, and no oil should be removed in advance to prevent rust.


2. Installation of metal random packing

① Pour it spirally from the tower wall towards the center to avoid direct scattering that may cause local suspension.

For towers with a diameter exceeding 1 meter, they need to be filled in layers, with each layer having a height of no more than 1 meter, and wooden boards should be laid at the same time to disperse the impact force.

③ Tap the tower wall or gently shake it with a wooden mallet to eliminate voids and increase the bulk density.


3. Installation of structured packing

①For small towers with a diameter of less than 800mm, structured packing is usually vertically lifted into the tower with lifting slings and stacked layer by layer.

②For industrial towers with a diameter larger than 800mm for the reducer sleeve, the structured packing is usually cut into several pieces, with an edge allowance reserved for assembly. After being placed inside the tower, they are assembled layer by layer and fixed with bolts or welding to ensure a tight joint (gap ≤2mm).


Installation precautions for metal tower packing: The edges of metal packing are sharp, and workers need to wear cut-resistant gloves when operating.
