style="text-indent:25px">生產(chǎn)不銹鋼無縫鋼管所用的原材料主要是連鑄圓管坯、軋(鍛)制圓鋼，確保鋼坯質量是把好鋼管質量的一道關，主要包括煉鋼水平、澆注和冷卻工藝，以及成形質量。首先是提高煉鋼水平，需降低有害元素和氣體(氮氫氧)，提高成分的均勻性和純凈度，減少非金屬夾雜物，同時改變其分布形態(tài)都是關鍵。鋼坯的成分不均勻且產(chǎn)生嚴重偏析時，會使軋制后的鋼管呈現(xiàn)嚴重的帶狀組織，從而降低鋼管力學性能和腐蝕性能，甚至不合格。非金屬夾雜物(如硫化物和氧化物、硅酸鹽)被壓成薄片，不*會影響鋼管的性能，而且可能會使鋼管在生產(chǎn)過程中產(chǎn)生裂紋。其次，完善澆注和冷卻工藝，減少皮下氣泡、皮下裂紋、疏松和縮孔也不能忽視，因為這些缺陷無論是哪一種，在穿孔和軋管過程中都有可能造成缺陷，有的缺陷在使用后放大，縮短了產(chǎn)品使用壽命；嚴重時在中間品就直接報廢，如內折。此外，鋼坯的外形偏差，如直線度、直徑和橢圓度，這都將直接影響到穿孔質量，造成荒管質量缺陷。</p><p style="text-indent:25px">不銹鋼無縫管的制造工藝是熱軋（擠壓無縫鋼管）：圓管坯，加熱，穿孔，三輥斜軋、連軋或擠壓，脫管，定徑（或減徑），冷卻，矯直，水壓試驗（或探傷），標記，入庫。冷拔（軋）不銹鋼無縫鋼管的軋制方法較熱軋（擠壓無縫鋼管）復雜。它們的生產(chǎn)工藝流程**步基本相同。不同之處從第四個步驟開始，圓管坯經(jīng)打空后，要打頭，退火。退火后要用專門的酸性液體進行酸洗。酸洗后，涂油。然后緊接著是經(jīng)過多道次冷拔（冷軋）再坯管，專門的熱處理。熱處理后，就要被矯直。2205不銹鋼管無縫管綜合了鐵素體和奧氏體較有益的性能，具有很好的抗氯離子應力腐蝕開裂。</p><div
