Practice shows that both ovality and eccentricity affect the casing collapse resistance obviously.───实践证明,不圆度和壁厚不均度对套管抗挤强度的影响是相当可观的。
cross-section distortion of bent tube is very small by using ball filler push bending process, with the ovality less than 1.5%.───运用珠粒填料推弯成形工艺成形出的管材截面畸变程度很小,椭圆度不超过1.5%。
Casing, cement and formation plane strain mechanical model are established, considering casing with initial ovality.───套管的不同初始椭圆度建立了套管、水泥环、地层平面应变力学模型。
Acceptable ovality for refractory performance is derived empirically from many years of observation.───对耐火砖衬可接受的椭圆度只可来通过多年观察得来经验取得。
The bended part of a tube has the ovality less than 2%, smooth inside wall without folding and even outside wall thickness without crack.───弯管部位管材的椭圆度小于2%,内壁光滑无皱褶,外部壁厚均匀无开裂。
The errors of the stand-off measurement and measurement errors made by pitch diameter gauge and ovality gauge are analyzed and compared.───分析比较了紧密距测量以及中径和椭圆度量规测量的误差。
Casing, cement and formation plane strain mechanical model are established, considering casing with initial ovality .───针对套管的不同初始椭圆度建立了套管、水泥环、地层平面应变力学模型。
Ovalisation meters measuring ovality during the test were used in the full scale testing, however.───在该测试中用于测量椭圆度的成椭圆形仪表也可用于大型的测试,但是。
Lacking internal support in the pipe, this pipe bending process creates some cross section ovality.───在管道内支持不足,这根管子弯过程中创造一些截面椭圆。
The cross-section distortion of bent tube is very small by using ball filler push bending process, with the ovality less than 1.5%.
Briefed in the paper are the characteristics, work principles and operation procedures of the pitch diameter gauge and ovality gauge used to check coupling threads.
According to the regressive equation being presented and the simulation results, the effect rules of process parameters on the ovality and optimal combination of process parameters were obtained.
The errors of the stand-off measurement and measurement errors made by pitch diameter gauge and ovality gauge are analyzed and compared.
In order to get the complex surface of piston skirt with barreled profile and varying ovality, a kind of arithmetic which can simply get a cubic curve was given.
Deviations of ovality, perpendicularity and partial concave - convex on large - scaled storage tanks are inevitably in construction.
