1、螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)送風(feng)(feng)(feng)(feng)(feng)：包括(kuo)新(xin)風(feng)(feng)(feng)(feng)(feng)送風(feng)(feng)(feng)(feng)(feng)、排(pai)風(feng)(feng)(feng)(feng)(feng)等送風(feng)(feng)(feng)(feng)(feng)方式，送風(feng)(feng)(feng)(feng)(feng)范圍(wei)廣，如工(gong)廠(chang)車間(jian)、生產現(xian)場(chang)等，由于(yu)孕育(yu)發生有害(hai)氣(qi)體，消防風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)，必(bi)要(yao)排(pai)出房間(jian)外，金屬風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)，室外空氣(qi)必(bi)要(yao)輸送到室內(nei)。此時必(bi)要(yao)一個大流量(liang)、小壓力的(de)(de)送風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)道。螺(luo)(luo)旋(xuan)(xuan)氣(qi)管(guan)(guan)異常(chang)得當。一般回(hui)收鍍鋅管(guan)(guan)，風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)價格(ge)，腐化(hua)(hua)性強、濕度不(bu)凡的(de)(de)地方一般回(hui)收不(bu)銹鋼管(guan)(guan)。2、螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)散裝運輸：有些工(gong)廠(chang)必(bi)要(yao)散裝顆(ke)粒，特殊是(shi)較小的(de)(de)顆(ke)粒，如使用(yong)(yong)螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)的(de)(de)泡沫塑料（結構:合成樹脂、增塑劑、穩定劑、色(se)料)顆(ke)粒。圓形風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)主要(yao)是(shi)在風(feng)(feng)(feng)(feng)(feng)管(guan)(guan)鐵皮(pi)上鍍上一層鋅，對(dui)鐵皮(pi)起到保(bao)護(hu)的(de)(de)作用(yong)(yong)。鋅鍍層經鈍化(hua)(hua)處理、染色(se)或涂(tu)覆(fu)護(hu)光劑后，能顯(xian)著提高其防護(hu)性和裝飾性。本錢低，效果(guo)好。

在加工(gong)(gong)時，不(bu)能(neng)在通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)道(dao)內設置加強架或加強筋，因(yin)為這樣會(hui)對(dui)(dui)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)道(dao)的質量產生一定(ding)的影響(xiang)，通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)路加工(gong)(gong)時不(bu)能(neng)采用(yong) S形插(cha)管(guan)(guan)(guan)(guan)(guan)與 C形直角(jiao)插(cha)管(guan)(guan)(guan)(guan)(guan)的連接方式，此(ci)外，對(dui)(dui)于(yu)一些特殊的通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)路，也不(bu)能(neng)采用(yong)按(an)扣(kou)式插(cha)，通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)制造后(hou)，還需用(yong)清洗(xi)液清洗(xi)，只(zhi)有達(da)到(dao)清洗(xi)標(biao)準后(hou)，才(cai)能(neng)及時封孔。如果是彩色(se)涂層鋼板通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)，應保持內壁光滑，且(qie)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)在加工(gong)(gong)過程中，還不(bu)能(neng)損壞涂層，若出現(xian)損壞部位，需用(yong)環氧(yang)樹脂(zhi)涂在表面(mian)即可。此(ci)外通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)在加工(gong)(gong)過程中，還要做好防腐蝕措施(shi)，不(bu)能(neng)用(yong)抽芯鉚釘，而且(qie)通(tong)(tong)風(feng)(feng)管(guan)(guan)(guan)(guan)(guan)道(dao)部件(jian)組裝時，必須先經過鍍鋅處理。

般(ban)送風機系統(tong)(tong)和空調系統(tong)(tong)的(de)設(she)(she)備(bei)(bei)，要(yao)在建筑物(wu)(wu)圍護(hu)結構施工完(wan)，障礙物(wu)(wu)已收拾，地(di)上無雜物(wu)(wu)的(de)條件下進行(xing)，對空氣潔凈系統(tong)(tong)的(de)設(she)(she)備(bei)(bei)，黃山(shan)風管，應(ying)在建筑物(wu)(wu)內部(bu)(bu)設(she)(she)備(bei)(bei)部(bu)(bu)件的(de)地(di)上已做好(hao)，墻面已抹灰(hui)完(wan)畢，室內無灰(hui)塵(chen)(chen)飛揚或有(you)防塵(chen)(chen)措(cuo)施的(de)條件下進行(xing)。一般(ban)除塵(chen)(chen)系統(tong)(tong)風管設(she)(she)備(bei)(bei)宜在廠房的(de)工藝設(she)(she)備(bei)(bei)設(she)(she)備(bei)(bei)完(wan)或設(she)(she)備(bei)(bei)基礎已確認，設(she)(she)備(bei)(bei)連接器、罩體方(fang)(fang)位已知的(de)情況下進行(xing)，查看現場預留孔洞方(fang)(fang)位、尺寸應(ying)符合圖紙要(yao)求，每邊比實(shi)踐截面大(da)100mm，作業地(di)址要(yao)有(you)相應(ying)的(de)輔助(zhu)設(she)(she)施，如梯子、架(jia)子、安(an)全防護(hu)、消防器材，并有(you)施工員的(de)技能、質量、安(an)全交底。
