        Ren Biao is currently Chief Engineer at Hilong Petrochemical Research Institute. He is adept at in-depth study of the leading edge of the market and front-line production. Through use of multiple exclusive national invention patents for OCTG coatings, he strongly promotes successful development of Hilong's exclusive  OCTG coatings and their wide application on domestic and international markets.

         

        Hilong Human Resources Director represented Hilong in congratulating the award-winning employees. He noted that "these two employees are amongst the leaders and pioneers of Hilong's technical innovation. In a variety of fields, they facilitate exceptional contributions toward Hilong's scientific and technical innovation strategy. This award is recognition from society of their contribution to the economy of Shanghai, and is also the honor of all Hilong employees."
