Fluorine-lined Equipment

Fiildtekii® is a professional brand focusing on the R&D, design, manufacturing and technical service of steel lined fluoropolymer anticorrosion equipment. We provide highperformance anticorrosion solutions for global customers in chemical, pharmaceutical, new energy, environmental protection, metallurgy and other industries, with core strengths in material compatibility, process stability and reliable quality.

Carbon steel and stainless steel are adopted as equipment base materials, balancing structural strength, pressure resistance and cost-effectiveness. Customization is available according to working conditions, media and temperature requirements.

• PTFE (Polytetrafluoroethylene): General high corrosion resistance, resistant to most strong acids, alkalis, high temperatures and organic solvents

• PFA (Perfluoroalkoxy Alkane): High purity, high temperature resistance, melt-processable, ideal for high-purity media and fine chemical applications

• FEP (Fluorinated Ethylene Propylene): Transparent, smooth, non-stick, well-balanced corrosion resistance, suitable for medium-temperature conditions

• ETFE (Ethylene-terafluoroethlene): Oxidation resistance, low permeability, suitable for severe corrosion and clean service conditions

  
  

  

  
  

• Steel lined fluoropolymer storage tanks (vertical, horizontal, atmospheric / pressurized)

• Steel lined fluoropolymer reactors (agitated reactors, synthesis reactors, polymerization reactors)

• Steel lined fluoropolymer heat exchangers (shell-and-tube, plate type)

• Steel lined fluoropolymer towers, filters, piping, fittings and other non-standard equipment

         

4. Mature Lining Processes

1. Sheet Lining Process: Mature and stable, suitable for large tanks and reactors, high bonding strength, vacuum resistant

2. Sheet Sticking Process: Flexible application, ideal for special-shaped parts and local reinforcement

3. Rotomolding Process: Integral seamless lining, uniform thickness, strong sealing performance

4. Isostatic Pressing Process: Dense and uniform lining layer, no bubbles, high wear and corrosion resistance
