                                                                                            發布時間:2019-09-18人氣:486

                                                                                            無縫鋼管用途廣泛。一般用途的無縫鋼管由普通的碳素結構鋼、低合金結構鋼或合金結構鋼軋制,產量多,主要用作輸送流體的管道或結構零件。

                                                                                            根據用途不同分三類供應:

                                                                                            a、按化學成分和機械性能供應;

                                                                                            b、按機械性能供應;

                                                                                            c、按水壓試驗供應:按a、b類供應的鋼管,如用于承受液體壓力,也要進行水壓試驗。

                                                                                            專門用途的無縫管有鍋爐用無縫管、化工電力用,地質用無縫鋼管及石油用無縫管等多種。

                                                                                            無縫鋼管具有中空截面,大量用作輸送流體的管道,如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。鋼管與圓鋼等實心鋼材相比,在抗彎抗扭強度相同時,重量較輕,是一種經濟截面鋼材。

                                                                                            廣泛用于制造結構件和機械零件,如石油鉆桿、汽車傳動軸、自行車架以及建筑施工中用的鋼腳手架等用鋼管制造環形零件,可提高材料利用率,簡化制造工序,節約材料和加工工時,已廣泛用鋼管來制造。

                                                                                            天津無縫鋼管廣泛應用于建筑鋼結構,石油化工,電力行業,大型場館,會展中心,升降機械,船舶制造,倉儲貨架,裝飾裝潢,交通設施,機場建設,鐵路車輛,橋梁支架,礦井支架,立體車庫,戶外廣告,健身器材,車輛制造等行業。用途廣泛。
