焊接鋼管也稱焊管,是用鋼板或帶鋼經(jīng)過卷曲成型后焊接制成的鋼管.焊接鋼管生產(chǎn)工藝簡單,生產(chǎn),品種規(guī)格多,設(shè)備資少,但一般強度低于無縫鋼管.20世紀(jì)30年代以來,隨著帶鋼連軋生產(chǎn)的發(fā)展以及焊接和檢驗技術(shù)的進步,焊縫質(zhì)量不斷提高,焊接鋼管的品種規(guī)格日益增多,并在越來越多的代替了無縫鋼管.焊接鋼管按焊縫的形式分為直縫焊接鋼管和螺旋焊接鋼管.
　　焊接鋼管采用的坯料是鋼板或帶鋼,因其焊接工藝不同而分為爐焊管,電焊(電阻焊)管和自動電弧焊管.因其焊接形式的不同分為直縫焊接鋼管和螺旋焊接鋼管兩種.因其端部形狀又分為圓形焊接鋼管和異型(方,扁等)焊接鋼管.

高頻焊接鋼管	鍍鋅焊接鋼管	公制焊接鋼管

焊接鋼管分類方法
按焊接方法不同可分為電弧焊管,高頻或低頻電阻焊管,氣焊管,爐焊管,邦迪管等.
電焊鋼管:用于石油鉆采和機械制造業(yè)等.
爐焊管:可用作水煤氣管等,大口徑直縫焊管用于高壓油氣輸送等；螺旋焊管用于油氣輸送,管樁,橋墩等.
按焊縫形狀可分為直縫焊管和螺旋焊管
直縫焊接鋼管:生產(chǎn)工藝簡單,生產(chǎn),成本低,發(fā)展較快.
螺旋焊接鋼管:強度一般比直縫焊管高,能用較窄的坯料生產(chǎn)管徑較大的焊管,還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管.但是與相同長度的直縫管相比,焊縫長度增加30~100%,而且生產(chǎn)速度較低.因此,較小口徑的焊管大都采用直縫焊,大口徑焊管則大多采用螺旋焊.
按用途又分為一般焊接鋼管,鍍鋅焊接鋼管,吹氧焊接鋼管,電線套管,公制焊接鋼管,托輥管,深井泵管,汽車用管,變壓器管,電焊薄壁管,電焊異型管和螺旋焊接鋼管.
一般焊接鋼管:一般焊接鋼管用來輸送低壓流體.用Q19,Q21,Q23鋼制造.也可采用易于焊接的其它軟鋼制造.鋼管要進行水壓,彎曲,壓扁等實驗,對表面質(zhì)量有要求,通常交貨長度為4-10m,常要求定尺(或倍尺)交貨.焊管的規(guī)格用公稱口徑表示(毫米或英寸)公稱口徑與實際不同,焊管按規(guī)定壁厚有普通鋼管和加厚鋼管兩種,鋼管按管端形式又分帶螺紋和不帶螺紋兩種.
鍍鋅焊接鋼管:為提高鋼管的性能,對一般鋼管(黑管)進行鍍鋅.鍍鋅鋼管分熱鍍鋅和電鋼鋅兩種,熱鍍鋅鍍鋅層厚,電鍍鋅成本低.
吹氧焊接鋼管:用作煉鋼吹氧用管,一般用小口徑的焊接鋼管,規(guī)格由3/8寸-2寸八種.用08,10,15,20或Q195-Q235鋼帶制成.為防蝕,有的進行滲鋁處理.
電線套管:也是普通碳素鋼電焊鋼管,用在混凝土及各種結(jié)構(gòu)配電工程,常用的公稱直徑從13-76mm.電線套套管壁較薄,大多進行涂層或鍍鋅后使用,要求進行冷彎試驗.
公制焊接鋼管:規(guī)格用無縫管形式,用外徑*壁厚毫米表示的焊接鋼管,用普通碳素鋼,碳素鋼或普能低合金鋼的熱帶,冷帶焊接,或用熱帶焊接后再經(jīng)冷撥方法制成.公制焊管分普能和薄壁,普通用作結(jié)構(gòu)件,如傳動軸,或輸送流體,薄壁用來生產(chǎn)家具,燈具等,要鋼管強度和彎曲試驗.
托輥管:用于帶式輸送機托輥電焊鋼管,一般用Q215,Q23,B鋼及20鋼制造,直徑63.5-219.0mm.對管彎曲度,端面要與中心線垂直,橢圓度有要求,一般進行水壓和壓扁試驗.
變壓器管:用于制造變壓器散熱管和其它熱交換器,采用普通碳素鋼制造,要求進行壓扁,擴口,彎曲,液壓試驗.鋼管以定尺或倍尺交貨,對鋼管彎曲度有要求.
異型管:由普通碳結(jié)結(jié)構(gòu)鋼及16Mn等鋼帶焊制的方形管,矩形管,帽形管,空膠鋼門窗用鋼管,主要用作農(nóng)機構(gòu)件,鋼窗門等.
電焊薄壁鋼管:主要用來制作家具,玩具,燈具等.近年來不銹鋼帶制作的薄壁管應(yīng)用很廣,家具,裝飾,欄柵等.
螺旋焊接鋼管:是將低碳碳素結(jié)構(gòu)鋼或低合金結(jié)構(gòu)鋼鋼帶按的螺旋線的角度(叫成型角)卷成管坯,然后將管縫焊接起來制成,它可以用較窄的帶鋼生產(chǎn)大直徑的鋼管.螺旋焊接鋼管主要用于石油,氣的輸送管線,其規(guī)格用外徑*壁厚表示.螺旋焊接鋼管有單面焊的和雙面焊的,焊接鋼管應(yīng)水壓試驗,焊縫的抗拉強度和冷彎性能要符合規(guī)定.
按端部形狀又分為圓形焊接鋼管和異型(方,扁等)焊接鋼管.
