class="khcont8">絎磨管采用滾壓加工，由于表面層留有表面殘余壓應力，有助于表面微小裂紋的封閉，阻礙侵蝕作用的擴展。從而提高表面抗腐蝕能力，并能延緩疲勞裂紋的產生或擴大，因而提高絎磨管疲勞強度。通過滾壓成型，滾壓表面形成一層冷作硬化層，減少了磨削副接觸表面的彈性和塑性變形，從而提高了絎磨管內壁的耐磨性，同時避免了因磨削引起的燒傷。滾壓后，表面粗糙度值的減小，可提高配合性質。滾壓加工是一種無切屑加工，在常溫下利用金屬的塑性變形，使工件表面的微觀不平度輾平從而達到改變表層結構、機械特性、形狀和尺寸的目的。因此這種方法可同時達到光整加工及強化兩種目的，是磨削無法做到的。無論用何種加工方法加工，在零件表面總會留下微細的凸凹不平的刀痕，出現(xiàn)交錯起伏的峰谷現(xiàn)象</div><p><p><img

石油專用管主要用于油、氣井的鉆探及油、氣的輸送。它包括石油鉆管、石油套管、抽油管。石油鉆管主要用于連接鉆鋌和鉆頭并傳遞鉆井動力。石油套管主要用于鉆井過程中和完井后對井壁的支撐，以保證鉆井過程的進行和完井后整個油井的正常運行。抽油管主要將油井底部的油、氣輸送到地面。 </p> <p> 石油套管是維持油井運行的生命線。由于地質條件不同，井下受力狀態(tài)復雜，拉、壓、彎、扭應力綜合作用作用于管體，這對套管本身的質量提出了較高的要求。一旦套管本身由于某種原因而損壞，可能導致整口井的減產，甚至報廢。 </p> <p> 按鋼材本身的強度套管可分為不同鋼級，即J55、K55、N80、L80、C90、T95、P110、Q125、V150等。井況、井深不同，采用的鋼級也不同。在腐蝕環(huán)境下還要求套管本身具有抗腐蝕性能。在地質條件復雜的地方還要求套管具有抗擠毀性能。<br /> 本章無縫鋼管廠家小編來為大家講一下無縫鋼管的繼續(xù)伸長時的應力 </p></div><p><img

絎磨管是一種通過冷拔或熱軋?zhí)幚砗蟮囊环N高精密的鋼管材料。由于精密鋼管內外壁無氧化層、承受高壓無泄漏、高精度、高光潔度、冷彎不變形、擴口、壓扁無裂縫等優(yōu)點，所以主要用來生產氣動或液壓元件的產品，如氣缸或油缸，可以是無縫管。絎磨管的化學成分有碳C、硅Si、錳Mn、硫S、磷P、鉻Cr。<br /> 絎磨管采用加工工藝<br /> 絎磨管采用滾壓加工，由于表面層留有表面殘余壓應力，有助于表面微小裂紋的封閉，阻礙侵蝕作用的擴展。從而提高表面抗腐蝕能力，并能延緩疲勞裂紋的產生或擴大，因而提高絎磨管疲勞強度。通過滾壓成型，滾壓表面形成一層冷作硬化層，減少了磨削副接觸表面的彈性和塑性變形，從而提高了絎磨管內壁的耐磨性，同時避免了因磨削引起的燒傷。滾壓后，表面粗糙度值的減小，可提高配合性質。滾壓加工是一種無切屑加工，在常溫下利用金屬的塑性變形，使工件表面的微觀不平度輾平從而達到改變表層結構、機械特性、形狀和尺寸的目的。因此這種方法可同時達到光整加工及強化兩種目的，是磨削無法做到的。無論用何種加工方法加工，在零件表面總會留下微細的凸凹不平的刀痕，出現(xiàn)交錯起伏的峰谷現(xiàn)象，滾壓加工原理：它是一種壓力光整加工，是利用金屬在常溫狀態(tài)的冷塑性特點，利用滾壓工具對工件表面施加一定的壓力，使工件表層金屬產生塑性流動，填入到原始殘留的低凹波谷中，而達到工件表面粗糙值降低。由于被滾壓的表層金屬塑性變形，使表層組織冷硬化和晶粒變細，形成致密的纖維狀，并形成殘余應力層，硬度和強度提高，從而改善了工件表面的耐磨性、耐蝕性和配合性。滾壓是一種無切削的塑性加工方法。<br
