The lining PTFE compensator is also called a retractor, an expansion joint, and a corrugated compensator. The compensator is divided into several types: corrugated compensator, sleeve compensator, rotary compensator, and square natural compensator. Among them, corrugated compensator is more commonly used, mainly to ensure the safe operation of corrosive pipelines, and has the following functions:
1. Compensate for axial, lateral and angular thermal deformation of the absorption pipe.
2. The amount of expansion and contraction of the corrugated compensator facilitates the installation and disassembly of the valve pipe.
3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
4. Absorb the amount of deformation of the pipeline caused by earthquakes and subsidence.
Lining PTFE compensator Scope Lining material: PTFE F4 Nominal diameter: DN25~1600(mm) Nominal pressure: PN0.6(Mpa) Operating temperature: -20~180°C Connection method: Flange outer body Material: Carbon steel, stainless steel Suitable medium: except for liquid alkali metal and naphthylamine solution, all strong acid, strong alkali, strong oxidizing medium and organic solvent.
The working principle of the lining PTFE compensator is based on the strength and thickness of the steel. The back shield combined with the excellent anti-corrosion performance of PTFE to resist the invaders of all corrosives with a flawless inner surface. Teflon protects the steel and steel. Teflon is the most loyal monk in the chemical industry.
