压力容器无损检测--换热器的无损检测技术

换热器是用于热量交换的压力容器之一,在石油、化工、电力和城市供暖等方面得到广泛使用。综述了管壳式换热器在制造和使用过程可能出现的缺陷和分别采用的各种无损检测方法,包括射线、超声、磁粉、渗透、电磁涡流和磁记忆检测等技术,分别介绍了这些无损检测方法在换热器的制造和使用过程中的应用情况和特点。

Nondestructive Testing of Pressure Vessels: Nondestructive Testing Technique for Heat Exchangers

Heat exchanger is one of the most widely used pressure vessels for heat exchanging. It is extensively used in petroleum industry, petrochemical industry, power industry and city heat supply system. The possibly emerged defects in heat exchanger and the nondestructive testing methods applied during its fabrication and use are reviewed. The applied NDT methods include radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, eddy current testing and metal magnetic memory testing. The application situation and characteristic of each NDT method applied in heat exchanger fabrication and use are introduced.
