Single Sphere PTFE Flexible Rubber Expansion Joint

Product Data

Product Introduction

PTFE rubber expansion joint is a common pipeline connection compensation device, which is composed of inner and outer rubber materials, steel wire rings and spherical PTFE lining. This type of joint has excellent corrosion resistance and high temperature resistance, and is suitable for corrosive medium transportation pipeline systems in industrial fields such as chemical, petrochemical, and pharmaceutical industries.

PTFE rubber expansion joint is divided into single sphere rubber expansion joint and double sphere rubber expansion joint.

What Are The Advantages And Disadvantages Of  PTFE Rubber Expansion Joint?

Advantages:

1. Corrosion resistance: PTFE lining has excellent corrosion resistance and is suitable for various corrosive media such as strong acids, alkalis, and organic solvents.
2. High temperature resistance: PTFE lining has excellent high temperature resistance and can be used in the temperature range of -50 ℃ to+180 ℃.
3. Excellent sealing performance: PTFE lining has excellent sealing performance, which can avoid medium leakage.
4. Excellent vibration resistance: The inner and outer rubber materials and steel wire coils can absorb vibration and displacement in the pipeline system, ensuring the stability of the system.
5. Easy to install and maintain: The single ball structure is simple and easy to install and maintain.
6. Wide scope of application: suitable for pipeline systems in various industrial fields such as chemical, petrochemical, pharmaceutical, and food.

Disadvantages:

1.High cost: PTFE rubber expansion joint has high corrosion resistance and high temperature resistance, so its material cost is relatively high, resulting in high product cost.

2.Installation and maintenance are complicated: PTFE rubber expansion joint needs to be installed according to strict installation requirements, and improper installation will affect the normal operation of the pipeline system. In addition, PTFE materials are more brittle than ordinary rubber materials, and if damage occurs during use, timely replacement is necessary to avoid pipeline leakage.

3.Stress limitation: Although PTFE rubber expansion joint can absorb vibration, noise and pressure waves in the pipeline system, its stress range is still relatively limited, and it may not be able to withstand excessive pressure changes under specific circumstances, so other types of expansion joint need to be selected for compensation.

In a word, PTFE rubber expansion joint is an excellent connecting element, which can effectively improve the working efficiency of rubber expansion joint in practical operation.

It should be noted that the PTFE rubber expansion joint should be selected with appropriate specifications and models according to the actual situation. At the same time, correct installation and maintenance should be carried out according to the product manual during use to ensure the use effect of the product.
