在管道设计中,总是要计算或选用管道支架跨距。而以各种公式、表格计算同样管径同样单位重量的管,所得到的跨距,各不相同,有的相差很大,使人莫遵所是。因而在选用中带有盲目性,心中无数。如果选了偏小数据,其结果必然造成支架个数增多,他投资增多。如厂区架空高支架,一个支架数百元,对建设投资的影响是很大的。如果选了偏大数据,是否安全?安全裕度多少?这也是需要知道的。管道支架跨距计算,既取决于管道强度,又取决于管道挠度。在这二者计算中,取其数值小者。通常按管道强度公式计算的跨距大,按管道挠度公
In pipe design, pipe support spans are always calculated or selected. In order to calculate pipes of the same unit diameter and the same pipe diameter by various formulas and tables, the spans obtained are different, and some are quite different from each other. Therefore, in the selection of blindness, countless hearts. If you select a small amount of data, the result will inevitably lead to an increase in the number of stents, and his investment will increase. For example, if the factory site is elevated with high supports and a support is a few hundred yuan, the impact on construction investment will be significant. If you choose too big data, is it safe? How much is the safety margin? This also needs to be known. Pipe span calculations depend not only on the pipe strength but also on the pipe deflection. In both calculations, the lower one is taken. The span calculated by the formula for pipe strength is usually large and the pipe deflection is
