class="khcont">無縫鋼管屈服強度的外在因素有:溫度、應變速率、應力狀態(tài)。隨著溫度的降低與應變速率的增高,材料的屈服強度升高,尤其是體心立方金屬對溫度和應變速率特別敏感,這導致了鋼的低溫脆化。應力狀態(tài)的影響也很重要。雖然屈服強度是反映材料的內(nèi)在性能的一個本質(zhì)指標,但應力狀態(tài)不同,屈服強度值也不同?！　∮绊憻o縫鋼管屈服強度的內(nèi)在因素有:結(jié)合鍵、組織、結(jié)構(gòu)、原子本性。如將金屬的屈服強度與陶瓷、高分子材料比較可看出結(jié)合鍵的影響是根本性的。將制管用的板料的兩側(cè)面進行機械加工,并使兩板邊的平行度達到規(guī)定的公差范圍內(nèi)，為制造出高精度的鋼管做準備。使鋼板板邊具有鋼板將成型鋼管半徑相等曲率半徑，鋼板預彎邊機：將銑邊機加工出兩邊焊接坡口的鋼板板邊進行預彎。防止成型機成型成型鋼管中產(chǎn)生過長的直邊，保證鋼板的圓度。全自動鋼管成型機：完成對各種金屬板料的彎曲成型。進行進一步的合縫和預焊，鋼管預焊機：將成型機成型合格的開口管坯,為內(nèi)、外焊做準備。焊接小車運送工件沿軌道行走，雙絲內(nèi)焊機：用于對大口徑直縫鋼管進行自動埋弧焊接,配合主機實現(xiàn)對工件的焊接。

class="khcont1">碳鋼管通常采用退火處理，而不銹鋼則采用固溶處理。幾何無縫化—內(nèi)外毛刺技術(shù)通常一個完整的內(nèi)毛刺系統(tǒng)由刀具、支持系統(tǒng)和調(diào)控系統(tǒng)三個部份組成，其技術(shù)關鍵在于刀具的形狀和壽命。內(nèi)毛刺的余高一般控制在0.2mm以內(nèi)，甚至0.1mm以內(nèi)。外毛刺技術(shù)較為簡單，于管體外裝外毛刺刮刀即可。物理無縫化—焊縫退火處理在高頻焊接過程中，由于趨膚效應、臨近效應和熱傳導的綜合作用，造成了管坯邊緣附近的溫度分布梯度，形成了熔化區(qū)、部分熔化區(qū)、過熱組織區(qū)、正火區(qū)、不完全正火區(qū)、回火區(qū)等特征區(qū)域。其中過熱區(qū)組織由于焊接的溫度在1100℃以上，奧氏體晶粒急劇長大，冷卻后晶粒粗大，在一定的化學成分和冷速條件下還會形成硬而脆的晶相。此外，由于溫度梯度的存在也會產(chǎn)生焊接應力。其綜合結(jié)果，焊縫區(qū)的綜合機械性能比母材低。焊管物理無縫化就是通過焊縫熱處理，達到應力、均化和細化組織、提高焊接熱影響區(qū)綜合機械性能的目的，而其根本目的是應力。直縫電阻焊鋼管與流體輸送用無縫鋼管相比具有相當?shù)募夹g(shù)優(yōu)勢，例如焊管壁厚較薄，尺寸精度較高，等等。
