什么是不銹鋼管?不銹鋼管的特征與用途

文章來源:    發布時間::2017-05-30     點擊量:81348

凡是兩端開口并具有中空的斷面,而且其長度與斷面周長之比較大的鋼材,都可以稱為鋼管。當長度與斷面周長之比較小時,可稱為管段或管形配件,它們都屬于管材產品的范疇。

不銹鋼管是一種經濟的斷面鋼材,是鋼鐵工業中的一項重要產品,通常占全部鋼材總量的8%一16%左右,它在國民經濟中的應用范圍極為廣泛。由于鋼管具有空心斷面,因而最適合作液體、氣體和固體的輸送管道;同時與相同重量的圓鋼比較,鋼管的斷面系數大、抗彎抗扭強度大,所以也成為各種機械和建筑結構上的重要材料。用不銹鋼管制成的結構和部件,在重量相等的情況下,比實心零部件具有更大的截面模數。所以,不銹鋼管本身就是一種節約金屬的經濟斷面鋼材,它是高效鋼材的一個重要組成部分,尤其在石油鉆采、冶煉和輸送等行業需求較大,其次地質鉆探、化工、建筑工業、機械工業、飛機和汽車制造以及鍋爐、醫療器械、家具和自行車制造等方面也都需要大量的各種鋼管。今年來,隨著原子能、火箭、導彈和航天工業等新技術的發展,不銹鋼管在國防工業、科學技術和經濟建設中的地位愈加重要。
