R&D

1.Welding of medium-carbon steel, for instance: eliminating, patching and repairing crank cracks of large-scale compressors, it is the only company that can do this business and has success experience with many enterprises in China. General Manager Mr. Zhi Xu has written an article published in "Nitrogenous fertilizer" in the 4th issue of 1997; For the large-scale imported Sulzer centrifuge P-100/3 (pushing type centrifuge), Our company has lift its separating efficiency at least 20% during putting them into using in chlorine-alkali industry through improving its distributing disk, feed screw and oil duct, obtains high praise. The glass lining tower section on the application of refining tower, obtains the the consistent high praise from the chlorine-alkali association.

2.The high-pressure self-tight flange ZY-LOC with the intellectual property rights of China only

The high-pressure self-tight flange ZY-LOC, our patently product  it breaks the drawback of traditional flange for separating the sealing and strengthen act on the one point, so, it can provide the comprehensive machanical properties and the life time. These are three similar products, Grayloc of United State, VECTOR of Britain, g-loc of Italy, on the world at present. For now, ZY-LOC successfully selected and applied to the largest state-level coal liquid project installment in Inner Mongolia by “China Petroleum & Chemical Corporation SEI”, otherwise, ZY-LOC has been used on the High-pressure PVC of Qilu Petroleum & Chemical Corporation, Chemical Sythetic Ammonia of Zhonghao Honghe, Carbamide of Hubei Huaqing Chemical Group Co., Ltd, and has obtained appreciative criticis. In 2008, Chengdu Zhiyuan Mechanical&Science Technology Co., Ltd was awarded the honorary title of “National R&D Partner” and “Outstanding Supplier” by Shenhua Group.

High-pressure self-tight flanges ZY-LOC may be widely applied to the areas of oil gas mining,  petroleum fining, chemical industry, aerospace, nuclear industry, ships industry, as well as synthetic fuel processing and so on,
