Teflon expansion joints are designed for pipes which come in contact with strong industrial and reactive materials. These expansion joints are capable of absorbing those movements, vibration and thermal expansion forces. These expansion joints are typically manufactured from PTFE (polytetrafluoroethylene), which is often called Teflon and is used in applications where the pressure capabilities and chemical resistance are extremely demanding.
Key Benefits & Features
Teflon expansion joints are versatile expansion joints often used in diverse industries, including Chemical Processing, Drugs, Food Processing, Fertilisers, and Waste Water Treatment. Their primary function is specifically to absorb axial, lateral, and angular movement from temperature, pressure, and mechanical vibration and to protect a piping system from these movements.
- Excellent Chemical Resistance
The biggest advantage of Teflon expansion joints, compared to other types of expansion joints, is the ability to withstand contact with very corrosive chemicals. PTFE is completely inert to all chemicals and can withstand prolonged contact with acids, alkalis, solvents, and oxidisers.
- Reliable Performance at High Temp/ Pressure
Both high-temperature (cryogenic) and low-temperature applications require dependable performance at varying temperatures. Teflon expansion joints can withstand high pressure and temperature. They provide reliable performance even in extreme temperature and pressure ranges, and therefore reduce stress on both the pipeline system and associated equipment.
- Flexibility & Absorption of Motion
Teflon expansion joints can absorb different types of motion due to their flexible construction, including axial compression, lateral deflection and angular rotation. The flexibility offered by a Teflon expansion joint reduces mechanical stresses, allows for improvement of misaligned piping and reduces vibration transmission through the piping system.
- Long Service Life & Minimal Maintenance
Due to the non-stick properties of PTFE (i.e. polytetrafluoroethylene) and its corrosion resistance, Teflon expansion joints do not require heavy service and maintenance. The resistance of Teflon expansion joints to the buildup of material, scaling or corrosion substantially extends the service life of Teflon expansion joints and therefore, reduces system downtime, excessive replacement of Teflon expansion joints and lower overall cost of operations.
- Design & Customisation Options
Teflon expansion joints are available in various designs, including moulded, convoluted, lined, or combinations of these types. When you approach expert manufacturers like Advanced Manufacturing System Inc, they can provide Teflon expansion joints custom-engineered for the type of material being used and can be reinforced, have vacuum supports or use external hardware based upon the purpose of the application, pressure rating or operating conditions.
Final Thought
Teflon expansion joints are a safe and cost-effective solution to efficiently operate in harsh chemical or thermal environments. Due to Teflon’s superior chemical resistance, high-temperature capacity, flexibility and durability, Teflon expansion joints provide a vital element to assure safe, durable and efficient operation
