1982: Hebei JULU Sealing Material Plant, the origin of leak sealing in China, was incorporated. In the past two decades, large amount of sealants were produced and sold to nationwide.

1982-1996: Sealants from Model HB-1 to Model HB-16 were successfully developed and applied. Different types of sealants with high quality are continuously brought to market.

1991-1996: Patents were approved for MG-92-1 and MG-96-1 Automatic Reposition Injection Guns. Continuously improved equipments and tools greatly relieved the intensity of the work.

1998: Successfully developed high-temperature resistant HB-18 (General) sealant. With this new model of sealant, we successfully sealed many leaks with temperature around 800℃, which occurred in large energy companies such as Sinopec Corp and PetroChina.

2001: Underwent large organizational changes in 2001 and the name was changed to Beijing JUYE HUANENG Science and Technology Co., Ltd. with headquarter relocated to Beijing. Meanwhile, the company was certified as high-tech enterprise by Beijing authority

2002: Was granted Quality Management System Certificate of ISO9001.

2002: Became a member of The Chemical Engineering Committee of the Chinese Construction Standardization Association.

2003: With approval by the former State Economic & Trade Commission, National Central Station for Chemical Engineering Construction Standardization and JUYE HUANENG take a leading role in writing up and administering the national industry standard for safety code and technical procedure of under temperature and pressure leak sealing. This project has been formally recognized by the authority and was reported by China Chemical Engineering News and China Petrochemal News in July 2003. The CEO of the
