国产SEW膨胀套管实物性能研究
Actual Products Performance Study on Domestic SEW Expandable Casing
摘要
Abstract
In order to further grasp the mechanical properties change situation of domestic BX55 and BX80 expansion casing before and after expansion,which produced by adopting SEW process (hot stretch-reducing electric welding),the microstructure and properties of two kinds of casing were tested.Experimental results showed that after radial expansion deformation of BX55 and BX80 grade expansion casing,the yield strength and tensile strength increased,but the elongation,impacttoughness and collapsing strength decreased,the various indexes can meet standards requirements of API SPEC 5CT,API RP5C3 and other related standards.关键词
