摘要
随着工程塑料管道应用的不断深入,管道的焊接质量检测及其性能评定成了一个重要的问题。介绍了工程塑料管道焊接接头的外观检测、内部缺陷的无损检测、焊接接头性能试验及快速裂纹扩展和慢速裂纹扩展方法等,这些对推动工程塑料管道的广泛使用具有重要的意义。
The welding quality test and performance assessment for pipes become more and more important with the application of engineering plastics pipe.It introduced the methods of appearance test of welding joint,nondestructive test of internal defect,performance test of welding joint,rapid and show crack spread.These methods are highly important to promot engineering plastics pipe used widely.
