1) tailor-welded tube with dissimilar thickness
差厚拼焊管
3) tailor-welded tube(TWT)
拼焊管
1.
To reveal the deformation regularity of tailor-welded tube(TWT)with dissimilar thickness during hydro-bugling,finite element analysis(FEA),experiment and mechanics analysis were conducted on the deformation behaviors of the thinner tube and the thicker tube,the initiation and expanding of the plastic deformation and the factors which affect bulging harmoniously.
为揭示差厚拼焊管内高压胀形的变形规律,采用有限元数值模拟和实验并结合力学分析,研究了差厚拼焊管胀形时薄壁管、厚壁管的变形差异,及塑性区的发生、发展过程和促进变形协调的力学和几何因素,分析了差厚变形条件下薄壁管、厚壁管的应力、应变发展历史。
4) thick tube welding
厚壁管焊接
5) X80 grade steel pipe with heavy thickness
X80厚壁焊管
6) difference of wall thickness in steel pipe
同管壁厚差
