金属孔板波纹填料是一种金属规整填料，通过在金属薄板上打孔、轧制小纹、大波纹后组装而成。这种填料具有阻力小、气液分布均匀、效率高、通量大且放大效应不明显的特点，适用于负压、常压和加压操作。特别是在改造板式塔时，使用金属孔板波纹填料效果尤为明显，其塔径范围可达φ150mm-12000mm以上。

与传统的金属丝网波纹填料相比，金属孔板波纹填料保持了其结构特点，同时改用表面有沟纹的孔板制成，从而提高了液体的均布和润湿性能，加强了传质效率。每盘单元高度为50-200mm，大直径超过1.5m，通常以分块形式制成。

应用场景方面，metallic mesh wave packing has the advantages of large throughput, low resistance, high efficiency and strong anti-blocking capacity. It is widely used in distillation, absorption, extraction and other processes in various industries such as chemical engineering, petrochemicals and natural gas processing.

According to the model of metallic mesh wave packing, the small tower diameter can range from 80-200MM while the large diameter can reach up to 13M. The liquid spray density can vary from 0.2-200M3/（M²·H）and it can be applied to negative pressure, normal pressure and positive pressure operations.

Metallic mesh wave packing is a high-efficiency regular filling material suitable for various industrial applications including chemical engineering, fertilizer production, oil refining and more.

The specifications of metallic mesh wave packing are as follows:

| Model | Peak Height (mm) | Specific Surface Area (m2/m³) | Water Flow Diameter dh? (mm) | Inclination Angle ω(°) | Voidage Ratio ε(%) | F Factor m/s√kg/m³ | Number of Theoretical Tray No./m |
