摘要
对某管道在安装监督检验中发现的异种钢焊接焊材选用问题进行了讨论和分析,提出了合理的异种钢焊材选用方法。碳钢与奥氏体不锈钢焊接选用25-13型焊材是比较适宜的。建议作出规定,在氧气管道异种钢焊接时不得选用18-8型焊材;对采用18-8型焊材焊接的在用氧气管道异种钢焊接接头加强在用监检力度,以保证氧气管道的安全运行。
Discussed and analyzed the material selection issue of dissimilar steel welding that found in a pipeline installation inspection, and gave a reasonable method for dissimilar steel welding material selection. The 25-13 material was more suitable for carbon steel and austenitic stainless steel welding. The 18-8 material shouldn＇t be used for oxygen pipeline dissimilar steel welding, and in service inspection for dissimilar steel welding joint that used 18-8 material should be enhanced to ensure the safe operation of oxygen pipeline.
