Advantages and Disadvantages of Aramid Packing and Gland Packing

Advantages of Aramid Packing:

1. Excellent Performance

a. High Strength: It has a very high tensile strength. It can withstand great pressure and is not easily damaged in sealing environments.

b. Heat Resistance: It can last a long time in high heat. It usually withstands high temperatures.

c. Chemical Resistance: It resists most chemicals, including acids, alkalis, and solvents. So, it is good for sealing corrosive media.

2. Good Wear Resistance

Aramid packing can resist friction and wear during use. It lasts longer, needs less frequent replacement, and cuts maintenance costs.

3. Self-lubricating

It is self-lubricating. It can reduce friction with rotating parts, like shafts. This lowers energy use and protects the shaft from damage.

4. Easy Installation

Aramid packing is usually soft and easy to cut and install. You can adjust it to different sealing parts to meet complex sealing needs.

Disadvantages of Aramid Packing:of Aramid Packing

1. High Price

Aramid packing is expensive due to its special performance and manufacturing process. This may increase equipment sealing costs.

2. High installation requirements

It is easy to install. But, improper installation may harm the seal. For example, poor packing or uneven installation can cause leaks.
