PTFE bellows compensator (also known as expansion joint) is used to compensate for the displacement and installation deviation of thermal expansion and contraction in pipeline systems with highly corrosive media, reducing the vibration of the pipeline system

PTFE bellows compensator (also known as expansion joint) is used to compensate for the displacement and installation deviation of thermal expansion and contraction in pipeline systems with highly corrosive media, reducing the vibration of the pipeline system. Basic parameters: ① nominal pressure MPa: -0.01, -0.05, 0.01, 0.05, 0.1, 0.25, 0.6, 1; ② The nominal diameter and compensation amount are shown in the table below; ③ The working temperature is -50~150 ℃. When it exceeds 150 ℃, it shall be resolved through agreement between the supply and demand parties.

The outer body is made of stainless steel metal compensator, which can withstand various concentrations of acids, alkalis, and salts, and also has the pressure of stainless steel compensator, without fear of collision. Available: DN25-1600mm Continuous fatigue life: 5000 cycles Pressure rating: PN0.6, 1.0, 1.6MPa Operating temperature: ≤ 200 ℃

Spray type PTFE compensator:

Can provide DN25-DN3000mm wave number unlimited, length ≤ 3000mm fatigue times: ≥ 10000 times pressure rating: PN0.25-2.5MPa operating temperature: ≤ 180 ℃

Rubber ball compensator:

Generally, products with relatively high pressure resistance and temperature resistance are made according to the requirements of the user.

Precautions for installing compensators

1. The installation of the compensator should be carried out in accordance with the requirements of the piping construction drawing and the compensator installation manual.

2. The pipeline for installing the compensator must be properly guided and fixed in order for the compensator to function properly. Therefore, the setting of guiding and fixing brackets must be strictly in accordance with the relevant technical data of the design department. For the principles of setting up guide and fixed brackets, please refer to the "Installation Guide for Ripple Compensators".

3. The bellows used for compensators are formed from thin-walled stainless steel plates, so during transportation, lifting, and welding, care should be taken not to damage the bellows due to knocking, scratching, arcing, welding spatter, and other reasons.

4. Before installation, foreign objects inside the corrugated pipe and pipeline should be removed to ensure the normal movement of the corrugated pipe.

5. Compensators with flow requirements should be installed according to the requirements of the medium flow arrow.

6. In order to keep the corrugated pipe in good working condition, the deformation of the compensator, including axial, lateral, torsional, etc., should not be used to adjust the installation error of the pipe system during installation.

7. After the compensator is installed, all yellow colored transport fixing screws should be removed before the system runs.
