一、概述 美国的Lawson等人于1966年发表了有关螺纹管的研究报告后,螺纹管作为一种高效换热元件而逐渐得到重视。一种单头螺纹管形状如图1所示。 目前螺纹管已经得到普遍关注。国外,在实验室对螺纹管进行了一系列的试验研究,研究螺纹管的传热、流阻、强度及结垢等性能。螺纹管在一些工业生产设备(如动 First, an overview of the United States Lawson, who published in 1966 on the study of the threaded pipe, the threaded pipe as a highly efficient heat transfer element and gradually get attention. A single-headed pipe shape shown in Figure 1. At present the threaded pipe has been widespread concern. Abroad, a series of experiments on the threaded pipe in the laboratory were conducted to study the heat transfer, flow resistance, strength and scaling of the threaded pipe. Threaded pipe in some industrial production equipment (such as moving
