用PFA模压的方法制造大口径(300-1200mm)蒸馏塔，使产品成型表面光亮如玉，加之我们特殊的菱形网加强工艺使模压PFA材料和钢体融为一体。衬氟层在高的成型压力挤压下形成了高密度塑钢体，具有耐强腐蚀和强渗透的特点，产品使用温度可以达到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.
