class="khcont">合金管具有中空截面，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。合金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，合金鋼管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。用合金鋼管制造環(huán)形零件，可提高材料利用率，簡化制造工序，節(jié)約材料和加工工時，如滾動軸承套圈、千斤頂套等，當前已廣泛用鋼管來制造。合金鋼管還是各種常規(guī)武器不可缺少的材料，槍管、炮筒等都要鋼管來制造。合金鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長相等的條件下，圓面積，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內部或外部徑向壓力時，受力較均勻，因此，絕大多數(shù)鋼管是圓管。</div><p><img

class="khcont6">高壓鍋爐管的生產工藝隨鋼種的不同各有差異。以珠光體型鉻鉬釩鋼為例，鍋爐管的生產工藝特點是：（1）管坯應剝皮，剝皮量通常為5mm；（2）由于鋼質較硬，管坯多用氧氣切割或鋸切；（3）由于鉻鉬釩鋼的導熱性比碳鋼低，加熱速度宜稍慢，加熱溫度為1120～1180℃，穿孔溫度為1100～1160℃；（4）這類鋼在1000～1100℃區(qū)間有良好的塑性和低的變形抗力，因而穿孔性能較好，變形參數(shù)可照中碳鋼或合金鋼（例如30CrMnSiA）選??；（5）軋后鋼管要正火和回火，正火溫度為950～980℃，回火溫度為730～750℃，保溫時間為2～3h；（6）鋼管尺寸公差較嚴，以保證對口焊接；管子長度盡可能長，以利于減少焊口數(shù)量。</div><div
