| Abstract: | Described in the article is the process flow of manufacturing the ~406.4 mmx7.92 mm X60 seamless steel pipe for pipe line service with the locally-induction heating＋hot-expanding process. With geometric dimensional inspection, mechanical property testing, and metallographic structure analysis of the finished product, it is verified that the product is of standard-required dimensions and homogeneous metallographic structure, and with comprehensive performance up to API Spee 5L PSL2. Thanks to the process of hot-expanding formation with simultaneous heat treatment, the inherent strain of the steel pipe is eliminated, and thus the production cycle is shortened, and in turn the operation costs for production of the high steel grade large-sized light-wall seamless steel pipe is reduced. |
