一种llowable Bend Radius

W.hat Does Allowable Bend Radius Mean?

T.he allowable bend radius is defined as the acceptable degree of deflection or curvature that a product pipe, drill pipe, mud motor or wireline system can safely tolerate without risk of significant damage to the component in question.

弯曲半径通常表示为以脚的向前距离表示，该部件需要完成90度转弯。

确定产品管道，钻杆，泥浆电机或有线系统的允许弯曲半径是任何水平定向钻孔（HDD）项目开始前最重要的方面之一。它是在计算进入和退出点的计算中使用的关键输入，可实现的深度和钻孔路径方向改变。

一世f the allowable bend radius of the drill pipe is exceeded the useful serviceable life of the drill pipe can be significantly reduced. The damage done to this drilling component can sometimes be barely noticeable, however, failure can occur after several subsequent drillings.

E.xceeding the bend radius of the product pipe can not only result in damage to the pipe, but it can also result in difficult pullback operations. Subjecting the pipe to tight bends increases the chance of the pipe becoming stuck during pullback.

确定和确保该部件在允许的弯曲半径内保留在允许的弯曲半径内，确保更快的回调，更少的镗孔误差，更少的停机时间和增加的钻串使用寿命。
