对于导热油炉焊接接头的探伤,根据不同受压元件的不同也有不同的要求。 1、导热油炉锅筒的纵环焊缝、封头拼接缝为100%射线或100%超声波加至少25%射线探伤,基本与现行的蒸汽锅炉和热水锅炉规程要求一致,这样即达到安全要求,又可以降低生产成本。 2、对于受热面管的对接接头的探伤,是按受热情况不同,即辐射热和对流热,分别提出要求。 3、导热油炉除气相炉的锅筒应进行机械性能试验外,其他管道的对接接头均不要求进行机械性能试验。因此,可以保证导热油炉焊缝的质量和性能。 4、导热油炉在焊接与检验上,与蒸汽锅炉或热水锅炉规程相比,其要求有一定的改变,为了保证焊接接头的质量和机械性能,产品施焊前必须进行焊接工艺评定。
