共板法蘭主要由角碼、法蘭夾，及與風(fēng)管一體相連的法蘭連接，這種形式風(fēng)管雖然造價較低（減少了角鋼用量，減少了制作角鋼法蘭的人工用量），但是實際應(yīng)用起來不如角鋼法蘭牢固，漏風(fēng)量也較大，且必須通過機(jī)床進(jìn)行加工，手工制作幾乎不能實現(xiàn)它的制作，通常只應(yīng)用于新風(fēng)系統(tǒng)，空調(diào)系統(tǒng)等，排煙系統(tǒng)還是經(jīng)常用角鋼法蘭連接的風(fēng)管。但是人防工程是不允許用共板法蘭連接。
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.
共板法蘭制作：
Common plate flange making:
標(biāo)準(zhǔn)直管由流水線上直接壓制成連體法蘭。
The standard straight pipe is directly pressed from the assembly line into the joint flange.
非標(biāo)直管、彎頭、三通、四通、配件等下料后，在單機(jī)設(shè)備上完成TDF法蘭成型。
The TDF flange is completed on the single machine after the non - standard straight pipe, elbow, three - way, four - way, fittings and so on.

法蘭角由模具直接沖壓成型，安裝時卡在四個角即可。
The flange angle is directly stamped by the die, and it can be stuck in four corners when the installation is installed.
法蘭間的連接用法蘭卡，由鍍鋅鋼板制作，經(jīng)法蘭卡成型機(jī)成型后切割成統(tǒng)一的尺寸供安裝連接使用。
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共板法蘭因與管道鋼板連成一體，不必像角鋼法蘭般打孔鉚接，在兩節(jié)管道的連接上用專用法蘭卡，四角加90度法蘭角后用螺栓連接。操作簡單，提高了效率，外觀平整、光滑，尺寸準(zhǔn)確，互換性強(qiáng)，產(chǎn)品的質(zhì)量穩(wěn)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.
