備注：

  • 標準：冷拔無縫鋼管的規(guī)格可能根據(jù)具體標準（如GB8163-87、GB3639-1999等）有所不同，這些標準規(guī)定了鋼管的尺寸、偏差、技術(shù)要求等參數(shù)。

  • 長度：鋼管通常長度為3~10.5m，可根據(jù)需求定制。

  • 材質(zhì)：常用材質(zhì)包括10號、20號鋼，以及16Mn、5MnV等低合金結(jié)構(gòu)鋼或40Cr、30CrMnSi等合金鋼。

  • 用途：適用于制造各種結(jié)構(gòu)低中壓鍋爐過熱蒸汽管、沸水管、機車鍋爐用過熱蒸汽管等，以及石油、化工、電力、建筑、機械制造等領(lǐng)域。

在實際應(yīng)用中，需根據(jù)具體需求選擇合適的規(guī)格和標準。
