共板法兰主要由角码、法兰夹，及与风管一体相连的法兰连接，这种形式风管虽然造价较低（减少了角钢用量，减少了制作角钢法兰的人工用量），但是实际应用起来不如角钢法兰牢固，漏风量也较大，且必须通过机床进行加工，手工制作几乎不能实现它的制作，通常只应用于新风系统，空调系统等，排烟系统还是经常用角钢法兰连接的风管。但是人防工程是不允许用共板法兰连接。
Flange, flange clamp is mainly composed of a bracket, and the air duct flange is integrally connected to the air ducts although low cost (reduced angle dosage, reduce the labor amount of production of steel flange), but the actual application as the angle steel flange firmly, the air leakage quantity is large, and must be processed by machine Handmade, can hardly achieve its production, usually only applied in fresh air system, air conditioning system, smoke control system is often used in angle steel flange connection pipe. But the civil air defense project is absolutely not allowed to use the common plate flange connection.
共板法兰制作：
Common plate flange making:
标准直管由流水线上直接压制成连体法兰。
The standard straight pipe is directly pressed from the assembly line into the joint flange.
非标直管、弯头、三通、四通、配件等下料后，在单机设备上完成TDF法兰成型。
The TDF flange is completed on the single machine after the non - standard straight pipe, elbow, three - way, four - way, fittings and so on.

法兰角由模具直接冲压成型，安装时卡在四个角即可。
The flange angle is directly stamped by the die, and it can be stuck in four corners when the installation is installed.
法兰间的连接用法兰卡，由镀锌钢板制作，经法兰卡成型机成型后切割成统一的尺寸供安装连接使用。
Flange connection with flange card, made of galvanized steel plate, after the flange forming machine molding, cut into a unified size for installation and connection.
TDF共板法兰因与管道钢板连成一体，不必像角钢法兰般打孔铆接，在两节管道的连接上用专用法兰卡，四角加90度法兰角后用螺栓连接。操作简单，提高了效率，外观平整、光滑，尺寸准确，互换性强，产品的质量稳定.
The TDF common flange is integrated into the pipeline and steel plate. It doesn't need to be riveted and riveted like angle flanges. Special flange cards are used on the connection of two pipelines, and the four angles plus 90 degrees flanges are connected by bolts. The operation is simple, the efficiency is improved, the appearance is smooth and smooth, the size is accurate, the interchangeability is strong, and the quality of the product is stable.
