摘要
Abstract
The polypropylene device in the certain petrochemical industry,which our company is in charge of manufacturing part of expansion joints.The product design temperature is -46 ℃ ,the pressure needs to choose A516 Gr.60 low-temperature steel materials which is recommended by ASME criterion. In order to ensure product performance we make process evaluation experiment preproduction,the experimental data show that the welding connector performance can satisfy with GB150-1998 or ASME requirement by choosing domestic J507DR ,J507 welding rod ,but it must draw up reasonable welding process and strictly control the welding heat input and the layer temperature.关键词
