Roller-coated PTFE tower

Rotary‑coating (rotary lining) equipment is a type of corrosion‑resistant vessel that uses carbon steel or stainless steel as the base material and employs a rotary rotational molding process to thermally bond fluoroplastics (such as ETFE, F40, PFA, FEP, etc.) to the inner surface.

Introduction


  • Product Description
  • Rotary‑coating PTFE (rotary lining) equipment is a type of corrosion‑resistant vessel that uses carbon steel or stainless steel as the base material and employs a rotary molding process to thermally bond fluoroplastics—such as ETFE, F40, PFA, and FEP—to the inner surface. Its key advantages include seamless construction, resistance to negative pressure, excellent impermeability, and high temperature tolerance, making it widely suited for highly corrosive chemical processing applications.

    1. Process

    • The tower section (carbon steel/stainless steel) is fully roller‑coated with a seamless lining.

    • Lined tower internals: distributors, supports, spray pipes, packing support rings, etc.

    2. Specifications

    • Diameter: DN300–DN4000

    • Single-section length: 1 m to 6 m

    • Lining: ETFE (2–4 mm), PFA (high-temperature)

    3. Performance

    • Temperature resistance: ETFE -60℃ to 180℃

    • Pressure resistance: positive pressure + vacuum (-0.09 MPa)

    • Corrosion resistance: resistant to moist chlorine gas, hydrogen chloride, sulfur dioxide, and various acids and bases.

    4. Features

    • Entirely seamless, preventing penetration by corrosive media within the tower.

    • Vacuum‑resistant, suitable for distillation, absorption, and vacuum desorption.

    • Smooth inner wall, anti-scaling, and prevents material buildup

    • Can be lined with fluoropolymer in sections and assembled on-site.

    5. Applicable Scenarios

    • Chemical distillation columns, absorption towers, scrubbing towers, and desorption towers

    • Environmental exhaust gas purification tower, acid mist absorption tower

    • High-purity media separation tower for the pharmaceutical and fine chemical industries

    • Highly corrosive operating conditions in chlor-alkali, fluorochemical, titanium dioxide, rare earth, and other industries

    The company specializes in the custom design and manufacture of non-standard roller‑coating PTFE equipment, leveraging a proven roller‑coating process with rigorous quality control at every stage. Our products deliver seamless, dense, corrosion‑resistant, and wear‑resistant performance, precisely tailored to meet customers’ operating conditions and dimensional requirements, ensuring reliable and long‑lasting equipment.
