Thread Content
On November 22, 2023, the project appraisal meeting for the \"Development of High-Pressure Vessels Using Domestic HIC Thick Steel Plates\" was held at LANSI Heavy Equipment Qingdao Company. The meeting was organized by the Office for the Localization of Major Equipment of Sinopec Group and Sinopec Engineering Construction Co., Ltd., hosted by LANSI Heavy Equipment Qingdao Company, and co-organized by Beijing Kechuang Zhifa Technology Co., Ltd. At the review meeting, the appraisal committee listened to a presentation by Sinopec Engineering Construction Co., Ltd. on the project titled \"Development of High-Pressure Vessels Using Domestic HIC Thick Steel Plates\". After review, inquiries, and discussions, the expert group unanimously agreed that the project of \"developing high-pressure vessels using domestically produced HIC thick steel plates\" holds great significance. The physical and chemical properties of the high-strength, hydrogen sulfide-resistant steel materials developed by Wuyang Steel Plant are comparable to those of imported steel plates, reaching an internationally advanced level. Lanshi Heavy Equipment Qingdao Company has innovated an intelligent and automated manufacturing technology for pressure vessels made from thick HIC steel plates. It has developed digital processes and equipment for shaping the cylinders and end caps of plate-welded pressure vessels, as well as advanced technologies for the efficient automatic welding and non-destructive testing of such vessels, thereby achieving digital manufacturing. The products of this project involve high technical complexity and strong innovation, possess independent intellectual property rights, and are at the international leading level as a whole. Having passed the technical appraisal, it is recommended that they be promoted for use. At present, China’s equipment manufacturing industry is in a crucial stage of transformation and upgrading. The development of domestically produced HIC thick-plate high-pressure vessels will further enhance Lanshi Heavy Equipment’s technical capabilities in manufacturing high-pressure vessels using domestically made, thick plates resistant to hydrogen sulfide corrosion, thereby contributing to the high-quality development of the equipment manufacturing industry. Technical experts and corporate representatives from units such as Sinopec Engineering Construction Co., Ltd., Sinopec Guangzhou Engineering Co., Ltd., Sinopec Jingmen Branch, Hegang Group Wuyang Iron and Steel Company, Hefei General Machinery Research Institute Co., Ltd., CNPC East China Design Institute Co., Ltd., as well as Lanxi Heavy Equipment and Lanxi Heavy Equipment Qingdao Company, attended the meeting.
Angang Wugang won the contract for the largest by weight and thickness steel intended for HIC applications in China. On April 3, 2020, the contract for over a thousand tons of thick steel plates resistant to hydrogen sulfide corrosion, which Angang Wugang had won, came into effect as planned. These steel sheets, with a thickness of 220 mm and a weight of over 50 tons each, will be used in the manufacture of cold high-pressure separators for a refining and chemical processing project undertaken by Sinopec, setting new records in China for both the weight and thickness of such steel sheets. In recent years, Hegang Wugang has made sustained efforts to further optimize its customer and product portfolios, adhering to the path of specialty steel production. It has actively pursued a strategy focused on creating high-quality branded products, using the upgrading of its customer base to drive the improvement of its product structure, thereby better meeting the differentiated needs of key strategic customers. Steel plates resistant to hydrogen sulfide corrosion are one of the flagship products under Hebei Iron and Steel Wuhan Iron & Steel’s strategy to produce high-quality branded products; they represent the company’s ‘top-performing’ product lines. These steel plates offer protection against hydrogen embrittlement, hydrogen corrosion, hydrogen-induced delamination, and sulfide corrosion, while also possessing good resistance to low-temperature embrittlement. They are primarily used in the manufacturing of equipment for petrochemical and thermal power plants, such as ultra-high-temperature petrochemical pipelines and ultra-high-temperature reactors. During a recent outreach visit, the marketing team of Hebei Iron and Steel Wugang learned that for a petrochemical renovation project carried out by Sinopec, the manufacturing of cold high-pressure separators requires steel materials that can withstand extreme temperatures, high pressures, and severe corrosion. Such materials must have a very low sensitivity to cracking, meet Z45 performance standards that are higher than usual, and also satisfy stringent technical requirements such as high-temperature mold welding at a length of 20H. The owner intends to use steel plates to manufacture this equipment in order to shorten the production cycle and reduce costs. However, since domestic steel manufacturers currently lack experience in using steel plates of such large thickness, they are still undecided whether to use imported thick plates or forgings. Although this project requires steel plates that are much thicker and heavier than those used in previous productions of similar products, making the production process extremely challenging, the marketing team at Hebei Iron and Steel Wugang made full use of the research and development expertise it has accumulated over the years to enhance the value of the products through advanced technology. They assigned dedicated personnel to closely monitor project progress; on one hand, they reached out to research institutions to obtain the technical parameters needed to meet the customer’s requirements, and on the other hand, they worked together with several top domestic manufacturers capable of producing the equipment required for this project. They conducted numerous meetings with the design agencies and project owners, as well as in-depth technical discussions, to provide detailed plans regarding product production, quality control, and delivery guarantees. In the end, HBWUGANG was able to leverage its strong technical advantages to convince the project owner and the design institute to approve the use of its steel plates as a substitute for imported ones.
Kudos to the development of the equipment manufacturing industry!
