若欲獲得尺寸更小和質(zhì)量更好的無縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。冷軋通常在二輥式軋機(jī)上進(jìn)行，鋼管在變斷面圓孔槽和不動(dòng)的錐形頂頭所組成的環(huán)形孔型中軋制。冷拔通常在0.5～100T的單鏈?zhǔn)交螂p鏈?zhǔn)嚼浒螜C(jī)上進(jìn)行。擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內(nèi)，穿孔棒與擠壓桿一起運(yùn)動(dòng)，使擠壓件從較小的?？字袛D出。此法可生產(chǎn)直徑較小的鋼管。精密管的焊接工藝。工藝：精密管中的Cr、Mo、V等強(qiáng)烈的碳化物形成元素有使接頭過熱區(qū)產(chǎn)生再熱裂紋的傾向。坡口機(jī)加工后(焊接前)MT檢查，無裂紋、無缺陷，焊前坡口及周圍表面清理(油污、除銹等)至見金屬光澤;坡口裝配避免強(qiáng)制組對(duì)。焊接前整體或局部預(yù)熱，焊縫兩邊各150mm范圍內(nèi)保證預(yù)熱溫度250～300度;層間溫度應(yīng)在預(yù)熱溫度控制范圍內(nèi)。

GTAW(純Ar氣體保護(hù))：建議采用TIG-R31(含V)焊絲，直徑2.5mm，電流100～140A。如果有一定壁厚，管徑不是很小的話，建議采取GTAW+SMAW。SMAW：焊條采用R337，規(guī)格可以按實(shí)際情況來定。焊接完成后清理飛濺，加熱至350～450℃，保溫并緩冷的后熱措施。12Cr1MoV采用相應(yīng)成分的耐熱鋼焊條，如R310、R312、R317、R316Fe，焊前預(yù)熱250～350℃，焊后回火處理710～750℃。焊補(bǔ)缺陷或焊后不能進(jìn)行熱處理時(shí)，也可采用奧氏體鋼焊條，如A302、A307。這時(shí)，由于焊縫與母材膨脹系數(shù)不同，同時(shí)在長期高溫工作時(shí)還可發(fā)生碳的擴(kuò)散遷移現(xiàn)象，而易于導(dǎo)致在融合區(qū)發(fā)生破壞。將精密鋼管送入精密鋼管機(jī)組，經(jīng)多道軋輥滾壓，精密鋼管逐漸卷起，形成有開口間隙的圓形精密鋼管，調(diào)整擠壓輥的壓下量，使精密鋼管間隙控制在1~3mm，并使焊口兩端齊平。如間隙過大，則造成鄰近效應(yīng)減少，渦流熱量不足，精密鋼管晶間接合不良而產(chǎn)生未熔合或開裂。如間隙過小則造成鄰近效應(yīng)增大，精密鋼管熱量過大，造成精密鋼管燒損;或者精密鋼管經(jīng)擠壓、滾壓后形成深坑，影響精密鋼管表面質(zhì)量。
