一般無縫鋼管是用10、20、30、35、45等質量碳結鋼16Mn、5MnV等低合金結構鋼或40Cr、30CrMnSi、45Mn2、40MnB等合結鋼熱軋或冷軋制成的。10、20等低碳鋼制造的無縫管主要用于流體輸送管道。45、40Cr等中碳鋼制成的無縫管用來制造機械零件，如汽車、拖拉機的受力零件。 <br /> 一般用無縫鋼管要保證強度和壓扁試驗。熱軋鋼管以熱軋狀態(tài)或熱處理狀態(tài)交貨；冷軋以熱以熱處理狀態(tài)交貨。低中壓鍋爐用無縫鋼管：用于制造各種低中壓鍋爐、過熱蒸汽管、沸水管、水冷壁管及機車鍋爐用過熱蒸汽管、大煙管、小煙管和拱磚管等。這樣就可以使鋼管受力均勻又能保證質量。 </p> <p>
