共(gong)板法(fa)蘭鍍(du)鋅(xin)風(feng)(feng)(feng)管(guan)(guan)又稱無法(fa)蘭風(feng)(feng)(feng)管(guan)(guan)，其制作形式比傳統的(de)矩形風(feng)(feng)(feng)管(guan)(guan)加工速度更快捷、更方便、更小的(de)漏風(feng)(feng)(feng)率。共(gong)板法(fa)蘭鍍(du)鋅(xin)風(feng)(feng)(feng)管(guan)(guan)廣(guang)泛應用于(yu)賓館、商場、紡(fang)織、化(hua)纖、石油化(hua)工、機械制造、儀表、電子(zi)、醫藥(yao)、煙(yan)草、食品、醫療、倉儲(chu)、寫字樓以及(ji)地(di)鐵、人防、地(di)下室等工程的(de)送(song)風(feng)(feng)(feng)、排風(feng)(feng)(feng)、排煙(yan)管(guan)(guan)道。鍍(du)鋅(xin)螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)的(de)厚度及(ji)規格根(gen)據(ju)要(yao)求(qiu)可(ke)變，通常在連接(jie)的(de)時候，鍍(du)鋅(xin)螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)兩端(duan)總是外(wai)接(jie)于(yu)配(pei)件（如彎頭、變徑(jing)）。一般情況下，兩端(duan)沒有凹槽并帶密封圈。

共板法(fa)蘭鍍(du)(du)鋅風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)就(jiu)是用于空(kong)氣(qi)輸(shu)送和(he)分(fen)(fen)布的(de)管(guan)(guan)(guan)(guan)道系(xi)統。鍍(du)(du)鋅風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可按截面形(xing)狀和(he)材質分(fen)(fen)類。按截面形(xing)狀，鍍(du)(du)鋅風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可分(fen)(fen)為圓形(xing)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，矩形(xing)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)，扁圓風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)等多種，其中圓形(xing)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)阻力(li)最(zui)(zui)小的(de)高度尺寸最(zui)(zui)大(da)，制作復(fu)雜。所以應(ying)用以矩形(xing)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)為主。
