PTFE-lined bellows compensator丨Chemical pipeline expansion joint

Features of PTFE-lined corrugated compensator:

1. It can be installed at the inlet, outlet or other high-frequency mechanical interfaces of the pump to reduce or eliminate its vibration and improve the service life and sealing performance of the pipeline. It solves the problem that the metal bellows cannot solve, reduces the cost of the enterprise, and improves the production efficiency. In addition, it can be used to absorb deviations between design and actual installation. It has the advantages of reliable operation, compact structure, strong compensation ability, corrosion resistance of various media and long service life.

2. The outer layer of the structure is 304 stainless steel bellows, which can withstand the pressure of ordinary pipes, and is lined with tetrafluoroethylene material, and tetrafluoroethylene is a polymer of tetrafluoroethylene. The English abbreviation is PTFE.

3. The chemical pipeline expansion joint overcomes the lack of corrosion resistance of stainless steel metal bellows; it solves the disadvantage that rubber and metal bellows are difficult to withstand high working pressure. In addition to strong corrosion resistance and high pressure resistance, the product also has the characteristics of high standardization, strong versatility, strong interchangeability, anti-aging, reliable sealing and long service life.

Technical parameters of PTFE-lined corrugated expansion joints:

Special expansion joints for chemical pipelines have the advantages of low chemical activity, resistance to various chemicals, weather resistance, corrosion resistance, etc., and are not easy to age. It also has strong blocking resistance, low coefficient of friction and excellent electrical properties. Under the condition of strong corrosive medium, the working temperature is high, which can meet the working temperature range of -40°C to 200°C. All chemical media can meet this temperature range. Under the condition of strong corrosive medium, the working temperature is high and can meet the working temperature range of – 40~200 C. All chemical media can meet this temperature range.
