Our product range includes PTFE sheet-lined equipment, PTFE spraying and roller coating, plastic-lined equipment, PTFE-lined steel pipes and fittings, and related fluoropolymer components made from PTFE, PFA, ETFE, FEP and other advanced materials.
PFA Coated Columns are designed for distillation, rectification, vapor-liquid separation, and purification of corrosive process media. They are used in pharmaceutical purification, fine chemical separation, and high-purity chemical production, where corrosion resistance and control of metal contamination are important considerations. Zhuoyan is a manufacturer and supplier of PFA-coated equipment in China.
The inner wall of each column is coated with PFA to provide a corrosion-resistant barrier between the process medium and the underlying metal. Zhuoyan can customize column height, diameter, internal packing supports, and port layout according to the separation process and equipment design requirements.
The column dimensions and internal arrangement should be selected according to the intended separation process. For packed-column applications, the internal support structure needs to accommodate the specified packing and its installation requirements. Port locations should also correspond to the required process connections.
For customized projects, providing a process drawing or equipment layout can help clarify the required dimensions, internal structure, and connection positions before manufacturing.
The internal PFA coating helps protect the column substrate from compatible corrosive liquids and vapors. By separating the process medium from the underlying metal surface, it also helps reduce the risk of metal contamination in high-purity chemical processing.
The smooth coated surface supports cleaning and helps reduce material adhesion. Actual performance depends on the process medium, operating conditions, and cleaning procedure. Chemical compatibility should be confirmed according to the medium composition, concentration, and operating temperature.
Before shipment, each PFA Coated Column undergoes high-voltage spark pinhole inspection to check the coating for potential discontinuities. This inspection helps identify coating defects before the equipment is installed in the process system.
Yes. The internal packing support can be designed for the specified packing arrangement. Please provide the packing type, dimensions, and relevant process requirements so the support structure can be evaluated for the application.
The original product specification states a continuous working temperature of up to 260°C for the PFA coating. However, the allowable operating temperature of the complete column must be confirmed according to the coating system, process medium, pressure or vacuum conditions, and equipment design. Please confirm the required operating conditions before specifying the equipment.
Yes. Shandong Zhuoyan New Materials Co., Ltd. can provide technical instructions for column installation. Sharing the equipment drawings, connection details, and installation requirements helps clarify the information needed for the project.
