Deep cultivation of gas storage and transportation equipment industry to comprehensively tackle key core technologies

IC660ELB921H From a small workshop in Beijing high-pressure gas cylinder factory, to becoming the leader of the domestic industrial gas cylinder industry, Tianhai Industry is moving toward the dream of “going abroad and going to the world”. He has been deeply engaged in the field of gas storage and transportation equipment for more than 50 years, from steel seamless gas cylinders to LNG welded insulated gas cylinders, from LNG cryogenic storage tanks to LNG gas supply systems for vehicle (ship) fuel, from sea and land LNG tank containers to completely “zero emission” hydrogen fuel cell hydrogen storage systems. Tianhai Industry continues to invest in innovation, cooperate with the upstream and downstream of the industrial chain, comprehensively fight the key core technology battle, and constantly promote the high-quality development of enterprises.

IC660ELB921H In the production and manufacturing workshop of Tianhai Low Temperature owned by Tianhai Industry, the requirements of each station and process are clearly shown, and the beautiful welding arc is dazzling, which everywhere reflects the details of the fine management of modern enterprises. In the past two years, Tianhai has independently completed the design, development and production of a number of domestic and foreign Marine tank demonstration projects, mainly including 12 170 cubic meter Marine tank projects of COSL PSV project and 2 180 cubic meter Marine deck tank projects supporting an 8,500 cubic meter C-type special LNG fuel refueling vessel. Both projects are Marine equipment integrating LNG storage tank and gas tank connection space (” TCS “for short), which requires high customization requirements in terms of product vacuum design, product weight and integrated system design. Tianhai Cryogenic team faced the difficulties, overcame the difficulties, and finally completed the production and delivery of all projects according to customer requirements, which was greatly recognized by customers, demonstrating the deep understanding and strong strength of Tianhai Cryogenic storage tank products.

IC660ELB921H Tianhai Industry has been market-oriented, continuous innovation and continuous improvement, and has made remarkable achievements in the research and development of hydrogen energy applications. In recent years, with the development of fuel cell vehicles, Tianhai Industry has accelerated the layout of hydrogen energy plate, and the 35MPa and 70MPa high-pressure hydrogen storage cylinders developed have been applied to the field of hydrogen fuel cell vehicles in batches, of which 70MPa high-pressure hydrogen storage cylinders have been successfully applied to the 2022 Zhangjiakou Winter Olympics hydrogen fuel cell bus demonstration operation project. In the Winter Olympic Games and Winter Paralympic Games, the lighting of the “big snowflake” amazed the world, from “fire” to “light fire”, this is the first hydrogen fuel torch in the history of the Olympic Games, and the high-pressure hydrogen storage and supply system matching the torch is also developed and manufactured by Tianhai Industry.

IC660ELB921H Through continuous research and development in the field, Tianhai Industry has become the first domestic enterprise to complete the national standard certification of 70MPa large-volume Type III bottles for hydrogen fuel commercial vehicles. In fact, since the development of hydrogen buses in China, each vehicle factory mainly uses 35MPa type III bottles as hydrogen supply units, and 70MPa type III bottles have not been carried on highway buses and public buses, thus greatly limiting the driving distance of commercial vehicles, thus hindering the development speed of hydrogen commercial vehicles. This time, Tianhai Industry broke through the multi-channel technical difficulties, and the 70MPa type III bottle designed and produced by itself was put on the market, which is of great significance for the development of hydrogen energy commercial vehicles, and promoted hydrogen fuel commercial vehicles to enter the era of long-distance operation.

In addition, in order to speed up the breakthrough of the “stuck neck” technology of the plastic inner liner carbon fiber fully wrapped composite gas cylinder (hereinafter referred to as: Type IV bottle), Tianhai Industry continues to improve the scientific and technological innovation mechanism and enhance the ability of independent innovation. Since 2016, after more than three years of independent innovation and research and development, we have mastered the core technology of IV bottle, applied for a number of invention patents and utility model patents, and become one of the first enterprises to obtain the manufacturing license of IV bottle in China. At present, Tianhai Industry has built a flexible IV bottle production line, IV bottle key technology breakthrough, will effectively promote the sustainable development of China’s hydrogen industry.
