產(chan)品特點：共板(ban)式(shi)法蘭(lan)(lan)風(feng)管又稱無法蘭(lan)(lan)風(feng)管，其制(zhi)作形(xing)(xing)式(shi)比傳統(tong)的(de)矩形(xing)(xing)風(feng)管加工(gong)(gong)速度更快捷、更方(fang)便、更小的(de)漏風(feng)率。其好處是節省材料(liao)，減(jian)少工(gong)(gong)程投(tou)資;漏風(feng)量(liang)小，降(jiang)低能耗(hao)，節省運行(xing)費(fei)用(yong)(yong)(yong)，頗受施工(gong)(gong)企業歡(huan)迎(ying)。 共板(ban)法蘭(lan)(lan)主要由(you)角(jiao)(jiao)(jiao)碼、法蘭(lan)(lan)夾，及與(yu)風(feng)管一(yi)體相連的(de)法蘭(lan)(lan)連接，這種形(xing)(xing)式(shi)風(feng)管雖(sui)然造價較低(減(jian)少了角(jiao)(jiao)(jiao)鋼(gang)(gang)用(yong)(yong)(yong)量(liang)，減(jian)少了制(zhi)作角(jiao)(jiao)(jiao)鋼(gang)(gang)法蘭(lan)(lan)的(de)人工(gong)(gong)用(yong)(yong)(yong)量(liang))，但(dan)是實(shi)際應(ying)用(yong)(yong)(yong)起來不(bu)如(ru)角(jiao)(jiao)(jiao)鋼(gang)(gang)法蘭(lan)(lan)牢固(gu)，且(qie)必須通過機床進行(xing)加工(gong)(gong)，手(shou)工(gong)(gong)制(zhi)作幾(ji)乎不(bu)能實(shi)現它的(de)制(zhi)作，通常只應(ying)用(yong)(yong)(yong)于新風(feng)系統(tong)，空調系統(tong)等，排(pai)煙系統(tong)還是經(jing)常用(yong)(yong)(yong)角(jiao)(jiao)(jiao)鋼(gang)(gang)法蘭(lan)(lan)連接的(de)風(feng)管。但(dan)是人防工(gong)(gong)程是不(bu)允許用(yong)(yong)(yong)共板(ban)法蘭(lan)(lan)連接。
