class="khcont">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(gè)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(gè)部份組成，其技術(shù)關(guān)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(yīng)、臨近效應(yīng)和熱傳導(dǎo)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(xué)成分和冷速條件下還會(huì)形成硬而脆的晶相。此外，由于溫度梯度的存在也會(huì)產(chǎn)生焊接應(yīng)力。其綜合結(jié)果，焊縫區(qū)的綜合機(jī)械性能比母材低。焊管物理無縫化就是通過焊縫熱處理，達(dá)到應(yīng)力、均化和細(xì)化組織、提高焊接熱影響區(qū)綜合機(jī)械性能的目的，而其根本目的是應(yīng)力。直縫電阻焊鋼管與流體輸送用無縫鋼管相比具有相當(dāng)?shù)募夹g(shù)優(yōu)勢(shì)，例如焊管壁厚較薄，尺寸精度較高，等等。
