摘　　要：PP-R(无规共聚聚丙烯)管材有着耐高温、卫生环保、使用寿命长等优点,在家装塑料管道系统中占据重要地位。在PP-R管材的施工安装时,由于施工方法不当等原因,经常出现管道脆裂、渗漏等问题。本文针对塑料管道承插焊接中出现的脆断问题进行原理分析,并提出了可行的问题解决方案。PP-R(Random Copolymer Polypropylene) pipes have advantages of high temperature resistance, health and environmental protection and long service life, and play an important role in the plastic pipe system for home decoration. During the construction and installation of PP-R pipes,problems such as pipeline cracking and leakage often occur due to improper working methods. This paper analyzes the principle of brittle fracture in plastic pipe socket welding, and puts forward feasible solutions to the working problem.
