Recently, Mechanical Science Research Institute, Harbin Welding Institute research projects' main coal chemical heavy pressure vessel wall surfacing weld and welding materials and welding technology "passed the results of identification. The project to control product quality and stability of the core, breaking the alloying elements and impurities precise control, material preparationand welding technology and other key technologies; complete low temperature steel, stainless steel and nickel-based alloys and other 19 varieties of welding materials development, presents an optimized support welding process, developed a high-performance product quality control standards and effective implementation. Bulk products have been widely used, significantly enhanced China's coal chemical industry's overall level of manufacturing technology and supporting capacity. The overall resultsreached the international advanced level, -70 ℃ low temperature steel welding materials used in the international leading level.
The scientific and technological achievements appraisal, recognition of the results of the project's advanced technology, complete sets of stability and product quality, in order to further promote the application provides a good support. The pressure vessel manufacturer with more than 70 factories through a lot of process evaluation and application practice shows that the technology is mature, stable and reliable quality, the products have formed industrialization. Will the company will continue to maintain product and service quality, increase publicity efforts, and strive in the "five" domestic coal chemical equipment manufacturing andpetrochemical, oil, marine engineering, nuclear power and other fields of application and make due contributions.
