自然补偿就是利用管道转弯作为补偿(图1),这是通常采用也比较常见的做法,笔者介绍一种计算方法,供大家参考。管路在运行中,由于存在着活动支座,妨碍管路横向位移,而使管路的应力增大,加之管壁厚度的不同,以及管材的刚度也不尽相同,因此,采用自然补偿管段来补偿热 Natural compensation is the use of pipe turns as compensation (Figure 1), which is usually used is also more common practice, I introduce a calculation method for your reference. Pipeline in operation, due to the existence of movable bearing, hinder the lateral displacement of the pipeline, leaving the pipeline stress increases, coupled with the different wall thickness, and the pipe stiffness are not the same, so the use of natural compensation pipe section To compensate for heat
