In 1995 our company of Sinopec Zhenhai Refining and chemical company manufacturing 4000m3 naphtha mixed spherical tank was the first maximum diameter of spherical tank shell plate length for the first time exceeded 10m mark, design and manufacturing requirements is higher than the national standard, the success of the assembly plant in a pre assessment by experts and won the "National new product award" to achieve the localization of large spherical tank, the first domestic 4000m3.

In 1998 China oil Dalian Petrochemical Co manufacturing 8000m3 four carbon spheres, diameter of 24800m, the product was home to design, manufacture and installation of the largest carbon four tank, the tank was first introduced in Japan NK-HIHTEN610U2 high strength steel plate, and won the Liaoning Province third outstanding new product award.

 2003 Guangzhou Huakai liquefied petroleum gas Co., Ltd design and manufacture of 10000m3 butane spheres is the largest spherical tank manufacturing company to design and manufacture level, identified by the Liaoning provincial economic and Trade Commission "is to design and manufacture of spherical tank in China's largest store of butane, for domestic initiative, to fill the domestic not to manufacture large spherical tank blank, make a great contribution to national saving foreign exchange, this project was issued by Liaoning province government outstanding new products in Liaoning province third-prize sixth.

Our company is Chongqing gas group made 6 10000m3 natural gas spherical tank, the diameter of 26800mm, structure of the fourteen pillars of the five band hybrid, this product was issued by Chongqing municipal government in the "science and technology progress prize two".

2011 Nanjing China oil measurement test center made 10m3 primary tank west east gas pipeline, the maximum design pressure (9.8MPa) and minimum diameter (2700mm), the successful production of this product solves the problem of high precision large caliber flowmeter natural primary standard, the product is the world's fifth, the first China qualified for pressure container weighing of natural gas, it successfully developed, not only to fill the gaps in gas flow measurement and advanced engineering, in order to achieve even beyond the domestic industry technical level and lay a solid foundation. At the same time also realized 10m3 primary tank localization, finished products rely on imports situation. This product in 2012 by the China Chemical Equipment Association identified as the product manufacturing technology advanced, to fill the gaps in the domestic, reached the international advanced level of similar products. Its successful development, and promote the technical progress of the industry, with good economic and social benefits".

 My company in 2012 for the Ningbo sea more new material limited company 1 million 380 thousand tons / year of propane and carbon four mixed use project "made of 15 6000m3 spherical tanks, tank diameter 22600mm, thickness of 52mm, with the 12 pillar structure in the form of 4 hybrid, this product is currently the highest design pressure (1.77MPa), the largest volume the propane tank, the success of this project, the Dalian Jinding tank manufacturing and then climb the peak.
