用PFA模壓的方法制造大口徑(300-1200mm)蒸餾塔，使產品成型表面光亮如玉，加之我們特殊的菱形網加強工藝使模壓PFA材料和鋼體融為一體。襯氟層在高的成型壓力擠壓下形成了高密度塑鋼體，具有耐強腐蝕和強滲透的特點，產品使用溫度可以達到220度。
     The PFA lined column made by the way of compression molding by PFA material, the diameter range from 300~1200mm. The high accuracy inner mould make the final molded surface as bright as jade. In addition, our special diamond mesh reinforcement technology makes the molded PFA material and the steel body integrated. The fluorine-lined layer forms a high-density plastic-steel body under high molding pressure extrusion, which has the characteristics of strong corrosion resistance and strong penetration resistance, and the product's use temperature can reach 220 degrees.
