如(ru)：1.低壓(ya)(ya)流體(ti)輸(shu)送用(yong)(yong)(yong)(yong)(yong)焊(han)(han)(han)接(jie)鋼管(guan)（GB/T3092-1993）也(ye)稱一般(ban)焊(han)(han)(han)管(guan)，俗稱黑(hei)管(guan)。是用(yong)(yong)(yong)(yong)(yong)于(yu)輸(shu)送水、煤氣(qi)、空(kong)氣(qi)、油和(he)取暖蒸汽(qi)等一般(ban)較低壓(ya)(ya)力流體(ti)和(he)其他用(yong)(yong)(yong)(yong)(yong)途的焊(han)(han)(han)接(jie)鋼管(guan)。鋼管(guan)接(jie)壁厚分(fen)為普通鋼管(guan)和(he)加厚鋼管(guan)；接(jie)管(guan)端形式分(fen)為不帶螺紋鋼管(guan)（光管(guan)）和(he)帶螺紋鋼管(guan)。鋼管(guan)的規格用(yong)(yong)(yong)(yong)(yong)公(gong)稱口徑(jing)（mm）表示(shi)，公(gong)稱口徑(jing)是內徑(jing)的近(jin)似值(zhi)。習慣上(shang)常用(yong)(yong)(yong)(yong)(yong)英寸(cun)表示(shi)，如(ru)11/2 等。低壓(ya)(ya)流體(ti)輸(shu)送用(yong)(yong)(yong)(yong)(yong)焊(han)(han)(han)接(jie)鋼管(guan)除(chu)直接(jie)用(yong)(yong)(yong)(yong)(yong)于(yu)輸(shu)送流體(ti)外(wai)，還(huan)大量用(yong)(yong)(yong)(yong)(yong)作(zuo)低壓(ya)(ya)流體(ti)輸(shu)送用(yong)(yong)(yong)(yong)(yong)鍍(du)鋅焊(han)(han)(han)接(jie)鋼管(guan)的原管(guan)。

2.低(di)壓流體輸(shu)送用鍍(du)(du)鋅(xin)焊(han)(han)(han)接(jie)鋼管(guan)(guan)（GB/T3091-1993）也(ye)稱鍍(du)(du)鋅(xin)電焊(han)(han)(han)鋼管(guan)(guan)，俗稱白管(guan)(guan)。是用于輸(shu)送水、煤(mei)氣(qi)、空氣(qi)、油及取(qu)暖(nuan)蒸(zheng)汽、暖(nuan)水等一般較低(di)壓力流體或(huo)其他用途(tu)的熱浸(jin)鍍(du)(du)鋅(xin)焊(han)(han)(han)接(jie)（爐(lu)焊(han)(han)(han)或(huo)電焊(han)(han)(han)）鋼管(guan)(guan)。鋼管(guan)(guan)接(jie)壁(bi)厚(hou)分(fen)為普通鍍(du)(du)鋅(xin)鋼管(guan)(guan)和(he)加厚(hou)鍍(du)(du)鋅(xin)鋼管(guan)(guan)；接(jie)管(guan)(guan)端形式分(fen)為不帶螺紋鍍(du)(du)鋅(xin)鋼管(guan)(guan)和(he)帶螺紋鍍(du)(du)鋅(xin)鋼管(guan)(guan)。鋼管(guan)(guan)的規格用公稱口徑（mm）表(biao)(biao)示，公稱口徑是內徑的近似值。習(xi)慣上常用英寸表(biao)(biao)示，如11/2 等。

3.普通碳素鋼(gang)電線套管（GB3640-88）是工(gong)業與民用建筑、安(an)裝機器設(she)備等電氣安(an)裝工(gong)程中(zhong)用于保護電線的鋼(gang)管。

4.直縫電焊(han)鋼(gang)(gang)管(guan)(guan)(guan)(guan)（YB242-63）是焊(han)縫與(yu)鋼(gang)(gang)管(guan)(guan)(guan)(guan)縱向平行的鋼(gang)(gang)管(guan)(guan)(guan)(guan)。通常分為公(gong)制電焊(han)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、電焊(han)薄壁管(guan)(guan)(guan)(guan)、變壓器冷卻油(you)管(guan)(guan)(guan)(guan)等等。

5.承壓流(liu)(liu)體輸(shu)送(song)用螺(luo)旋縫(feng)埋(mai)弧(hu)焊鋼管(guan)（SY5036-83）是以(yi)熱軋鋼帶(dai)卷作(zuo)管(guan)坯，經(jing)常溫螺(luo)旋成(cheng)型，用雙(shuang)面埋(mai)弧(hu)焊法焊接(jie)，用于承壓流(liu)(liu)體輸(shu)送(song)的螺(luo)旋縫(feng)鋼管(guan)。鋼管(guan)承壓能力強，焊接(jie)性能好，經(jing)過(guo)各種嚴格的科(ke)學檢驗和測試，使用安全可靠(kao)。鋼管(guan)口徑大，輸(shu)送(song)效(xiao)率高，并可節約鋪設管(guan)線(xian)的投資。主要用于輸(shu)送(song)石(shi)油、天然氣的管(guan)線(xian)。
