What is PFA management?
PFA pipe is a kind of high-performance plastic pipe made of perfluoroalkoxy resin, which has excellent high and low temperature resistance and almost no chemical corrosion characteristics. Because of its excellent electrical insulation and smooth non-viscosity, it is often used to transport corrosive media and high purity fluids, and is widely used in semiconductor, chemical, pharmaceutical and other fields.
What is the welding method of PFA pipeline?
Triflure PFA tubes are usually welded using hot melt welding technology to ensure tightness and structural integrity of the joints. The specific steps are as follows:
Preparation stage: First clean the end of the PFA pipe and accessories to be welded, remove impurities such as grease and dust, and ensure that the surface is clean.
Assembly positioning: The pipe and pipe fittings are accurately aligned and fixed in the special fixture to ensure that the welding parts are tightly fitted.
Heating welding: Use professional PFA welding machine or infrared heating equipment, according to the specified temperature and time to evenly heat the welding area until the material is softened.
Butt fusion: When the PFA material reaches the appropriate melting temperature, the two parts of the pipe are quickly pressed together to form a firm and seamless joint.
Cooling molding: Maintain the pressure, let the welding point cool and solidify naturally, ensure that the interface shape is stable, no deformation or leakage.
Quality inspection: After the completion of welding, through visual, pressure test or leak detection, verify whether the welding quality meets the standard requirements.
What are the applications of PFA tubes in heat exchangers?
Manufacture corrosion resistant heat exchange elements: PFA tubes can be used as heat transfer tubes inside heat exchangers, especially for the treatment of strong acids, alkali or other corrosive liquids, such as waste liquid recovery systems in chemical production and heat exchange links in the production process of precision chemicals.
Working in high temperature environment: Because PFA materials can withstand long-term operating temperatures of up to 260 ° C, and can still maintain good physical properties at high temperatures, PFA tube heat exchangers are ideal for high temperature processes requiring efficient heat transfer and anti-corrosion protection.
Occasions with high cleanliness requirements: in the biopharmaceutical and microelectronics industries, triflurai PFA tubes are widely used in the heat exchangers of ultra-pure water preparation systems and other key equipment that need to prevent pollution because of their easy adsorption of impurities and easy cleaning.
structural flexibility: PFA tube plasticity is strong, easy to process into different shapes and sizes of heat exchange tube, easy to design customized heat exchanger structure according to actual needs.
