摘 要: 热拱不仅使管道产生弯曲位移,而且能产生相当大的热应力,弯曲位移与热应力都会给管道带来极大的潜在危险。本文介绍了几种热拱的工程实例及处理方法;在工程上要尽量避免产生热拱,以保证管道的安全。 Thermal blowing doesn't only lead to bending displacement of pipelines, but also produces great thermal stress. Bending displacemen and thermal stress are risky for pipelines. This paper introduces several real projecting cases of thermal blowing and related solutions. In rea engineering projects,thermal blowing shall be avoided for the safety of pipelines.
