　　下面(mian)簡(jian)單的介紹幾種螺旋焊管(guan)的應用：

　　1、 一般(ban)螺旋(xuan)焊管用于水(shui)、煤(mei)氣、空氣、油和取暖蒸汽等一般(ban)較(jiao)低壓力流體(ti)的輸送。

　　2、 普(pu)通碳素鋼電線(xian)套管(GB3640-88)是工業與民(min)用(yong)(yong)建筑、安裝(zhuang)機器設備等電氣安裝(zhuang)工程中用(yong)(yong)于保護電線(xian)的(de)鋼管。

　　3、 直縫(feng)電螺旋焊管(YB242-63)是(shi)焊縫(feng)與鋼(gang)(gang)管縱向平(ping)行的鋼(gang)(gang)管。通常分(fen)為公制(zhi)電螺旋焊管、電焊薄壁(bi)管、變(bian)壓器冷卻油(you)管等等。

　　4、 承(cheng)(cheng)壓流(liu)體輸送用(yong)螺旋縫(feng)埋弧(hu)(hu)螺旋焊管(guan)(guan)(SY5036-83)是(shi)以熱軋鋼(gang)(gang)帶卷作管(guan)(guan)坯(pi)，經常溫螺旋成型，用(yong)雙面埋弧(hu)(hu)焊法(fa)焊接，用(yong)于承(cheng)(cheng)壓流(liu)體輸送的螺旋縫(feng)鋼(gang)(gang)管(guan)(guan)。鋼(gang)(gang)管(guan)(guan)承(cheng)(cheng)壓能力(li)強，焊接性能好，經過各種(zhong)嚴格(ge)的科(ke)學檢驗和測試，使用(yong)安(an)全可靠。鋼(gang)(gang)管(guan)(guan)口徑大，輸送效率(lv)高，并可節約鋪設管(guan)(guan)線的投資。主要用(yong)于輸送石油、天然氣的管(guan)(guan)線。

　　5、 承壓流體(ti)輸(shu)送(song)(song)用(yong)(yong)螺(luo)(luo)旋縫高(gao)頻(pin)(pin)螺(luo)(luo)旋焊管(guan)(guan)(SY5038-83)是以熱軋鋼(gang)帶卷作管(guan)(guan)坯，經常溫螺(luo)(luo)旋成(cheng)型，采用(yong)(yong)高(gao)頻(pin)(pin)搭接(jie)焊法焊接(jie)的，用(yong)(yong)于(yu)承壓流體(ti)輸(shu)送(song)(song)的螺(luo)(luo)旋縫高(gao)頻(pin)(pin)焊鋼(gang)管(guan)(guan)。鋼(gang)管(guan)(guan)承壓能力強，塑性(xing)好，便于(yu)焊接(jie)和(he)(he)加(jia)工(gong)成(cheng)型;經過各種嚴格和(he)(he)科學(xue)檢驗和(he)(he)測試，使用(yong)(yong)安全可靠，鋼(gang)管(guan)(guan)口徑大，輸(shu)送(song)(song)效率高(gao)，并可節(jie)省鋪(pu)設(she)管(guan)(guan)線的投資。主(zhu)要用(yong)(yong)于(yu)鋪(pu)設(she)輸(shu)送(song)(song)石(shi)油、天(tian)然氣(qi)等的管(guan)(guan)線。

　　6、 一般低壓流體輸(shu)送用螺旋(xuan)縫埋(mai)弧(hu)焊鋼(gang)管(SY5037-83)是(shi)以熱(re)軋(ya)鋼(gang)帶卷(juan)作管坯，經常(chang)溫螺旋(xuan)成(cheng)型，采用雙面自動(dong)埋(mai)弧(hu)焊或(huo)單(dan)面焊法制成(cheng)的用于水、煤氣、空氣和蒸(zheng)汽(qi)等一般低壓流體輸(shu)送用埋(mai)弧(hu)焊鋼(gang)管。

　　螺旋焊(han)管(guan)(guan)可以采用布、洛(luo)、維(wei)三種(zhong)硬(ying)度試(shi)驗(yan)方法(fa)，測(ce)定HB、HRB(或HRC)和HV硬(ying)度值(zhi)，三種(zhong)硬(ying)度值(zhi)只測(ce)其一即可。無縫鋼管(guan)(guan),無縫精(jing)密鋼管(guan)(guan),精(jing)軋鋼管(guan)(guan)的測(ce)試(shi)方法(fa)與此相似(si)。
