style="text-indent:25px">電線套管：也就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。公制焊管：規(guī)格用作無縫管形式，用外徑*壁厚毫米表示的焊接鋼管，用普通碳素鋼、優(yōu)良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，要保證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、Q235A、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、橢圓度有一定要求，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，對鋼管彎曲度有一定要求。焊管在倉庫里不得與酸、堿、鹽、水泥等對鋼管有侵蝕性的材料堆放在一起。鎮(zhèn)江焊管銷售廠家</p><p style="text-indent:25px">在無縫焊管使用時水平安裝的管道每米允許偏差1mm。鎮(zhèn)江焊管銷售廠家</p><p style="text-indent:25px">較小口徑的焊管采用直縫焊，大口徑焊管則多采用螺旋焊；按鋼管端部形狀分為圓形焊管和異型（方、矩型等）焊管；按材質(zhì)和用途不同分為礦用流體輸送焊接鋼管、低壓流體輸送用鍍鋅焊接鋼管、帶式輸送機托輥電焊鋼管等。根據(jù)現(xiàn)行國標中的規(guī)格尺寸表，按外徑*壁厚由小到大排序。焊管常用材質(zhì)為：Q235A，Q235C、Q235B、16Mn、20#、Q345、L245、L290、X42、X46、X60、X80、0Cr13、1Cr17、00Cr19Ni11、1Cr18Ni9、0Cr18Ni11Nb等。普通碳素鋼電線套管（gb3640-88）是工業(yè)與民用建筑、安裝機器設(shè)備等電氣安裝工程中用于保護電線的鋼管。直縫電焊鋼管（yb242-63）是焊縫與鋼管縱向平行的鋼管。通常分為公制電焊鋼管、電焊薄壁管、變壓器冷卻油管而鋼管一般分兩大類，一類叫焊接鋼管，另一種則是無縫鋼管。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)效率高，品種規(guī)格多，設(shè)備資少，但一般強度低于無縫鋼管。鎮(zhèn)江焊管銷售廠家</p></p><br
