Comparison of Specification Differences and Applications between Thin Wall and Thick Wall PFA Pipes

2024-04-21

1、 Overview of Common Thin Wall PFA Pipe Specifications

Thin walled PFA pipes, due to their thin wall thickness, good flexibility and flexibility, are widely used in fields that require high flexibility and precision control.

Its specifications are rich and diverse, with common inner diameter specifications ranging from small diameters such as 1mm to larger diameters such as tens of millimeters, such as 1mm, 2mm, 3mm, 4mm, 6mm, 8mm, 10mm, 12mm, etc. The wall thickness is usually between 0.2mm and 1.5mm, and the specific values depend on the manufacturer and customer needs.

This type of thin-walled PFA tube is lightweight and has low loss, making it particularly suitable for fluid transmission and protection circuits in industries such as fine chemicals, biomedicine, and semiconductor processing.


2、 Overview of Common Thick Walled PFA Pipe Specifications

Compared to thin-walled PFA pipes, thick walled PFA pipes pay more attention to their strength and durability in design and manufacturing. Its inner diameter specifications are also diverse, but the wall thickness is usually larger than that of thin-walled PFA pipes, ranging from 1.5mm to 5mm, or even higher. Corresponding inner diameter specifications are the same, such as 10mm, 15mm, 20mm, 25mm, etc. They can maintain stable performance in more harsh working environments such as high pressure, high temperature, and strong corrosion.

Thick walled PFA pipes are often used in piping systems of chemical equipment, high-temperature steam transportation, and nuclear industry cooling water circulation systems that require stronger structural stability and resistance.

3、 The difference in application between thin-walled and thick walled PFA pipes

1. Pressure resistance performance: Due to differences in wall thickness, the pressure resistance strength of thick walled PFA pipes is significantly higher than that of thin-walled PFA pipes, making them more suitable for use in high-pressure environments and effectively resisting the risk of deformation or rupture caused by internal fluid pressure.

2. Temperature resistance: Although both types of PFA pipes have good high-temperature resistance, under extreme high temperature conditions, thick walled PFA pipes can better maintain their shape without changes and maintain normal operation due to their stable structure.

3. Fatigue resistance: Under repeated thermal expansion and contraction or frequent bending conditions, thick walled PFA pipes can better resist fatigue failure caused by stress cycles due to their strong mechanical properties.

4. Application areas: Thin walled PFA pipes, due to their good flexibility and lightweight texture, are more commonly used for fluid transmission and protection in precision instruments, clean rooms, biomedicine and other fields; Thick walled PFA pipes are commonly used in areas such as heavy industry and energy engineering that require higher pipeline performance.
