The 2010 National Model Workers and Advanced Workers Commendation Conference was solemnly held on the morning of April 27th at the Great Hall of the People in Beijing. Qiu Xiaolai, Chief Engineer of Zhejiang Chaoda Valve Co., Ltd., was named a 2010 National Model Worker. Qiu Xiaolai, Chief Engineer of Chaoda Valve Group (formerly Zhejiang Chaoda Valve Co., Ltd.), attended the 2010 National Model Workers and Advanced Workers Commendation Conference, where Party and state leaders presented him with the National Model Worker certificate. A model worker, or “labor model” for short, is an honorary title awarded to workers who have made outstanding achievements in socialist construction, after democratic selection by employees, review by relevant departments, and approval by the government. The model worker awarded by the Central Committee of the Communist Party of China and the State Council is the “National Model Worker.” This award is attributed to the Yongjia County Party Committee and County Government’s emphasis on scientific and technological talent. In 1995, Qiu Xiao, former deputy director of the Valve Research Office of the General Machinery Research Institute of the Ministry of Machinery Industry, joined Chaoda Valve Group as chief engineer and director of the Technology Research and

Chaoda Valve Group Co., Ltd. has obtained the TS Special Equipment Manufacturing License (Level A1), certificate number TS2710359-2021. The certified product range includes valves, specifically gate valves, ball valves, globe valves, check valves, regulating valves, and butterfly valves. The approving authority is the State Administration for Quality Supervision, Inspection and Quarantine of the People’s Republic of China, and the issuing authority is also the State Administration for Quality Supervision, Inspection and Quarantine of the People’s Republic of China. The Special Equipment Manufacturing License, also known as TS certification, refers to the administrative action taken by the national special equipment safety supervision and management department to supervise and inspect relevant units involved in the production, design, manufacturing, installation, modification, repair, use, and inspection of special equipment.

Shandong Shenchi Chemical Group, established in December 2001, has developed into a diversified joint-stock enterprise group with petrochemicals as its leading industry, and isoprene-butyl synthetic rubber, chemical trading, and real estate. The group’s parent company is Shandong Shenchi Chemical Group Co., Ltd., which owns three subsidiaries: Shandong Shenchi Petrochemical Co., Ltd., Dongying Taizhi Chemical Co., Ltd., and Dongying Yellow River Estuary Real Estate Co., Ltd. Shandong Shenchi Petrochemical Co., Ltd. is a privately-owned enterprise engaged in petrochemical production, with main products including gasoline, diesel, liquefied petroleum gas, wax oil, heavy oil, light oil, light hydrocarbons, propylene, oil slurry, MTBE, and residual oil. Delayed coking is a secondary petroleum processing technology that uses hydrogen-depleted heavy oil as feedstock, undergoing deep thermal cracking and condensation reactions at high temperatures (approximately 500℃) to produce rich gas, crude gasoline, diesel, wax oil, and coke. Delayed coking feedstock can be heavy oil, residual oil, or even asphalt. Delayed coking products include gas, gasoline, diesel, wax oil, and coke. The bellows-sealed ball valve mainly consists of a valve body, upper valve stem, bellows, lower valve stem, and pins. Both the upper and lower valve stems have a pair of helical grooves (with the same helical direction),

Chaoda Valve Group Co., Ltd. was awarded a banner by the Gas Transmission and Distribution Branch of Beijing Gas Group Co., Ltd., inscribed with “Strong Support for the Olympics.” In August 2008, with the active support of Chaoda Valve, Beijing Gas Group Co., Ltd. successfully completed the work of ensuring a safe and stable gas supply during the holiday period. Fully welded ball valves are suitable for: gas output pipelines, main lines, and branch supply pipelines; output pipelines, main lines, and branch lines of large heating equipment; opening and closing of pipelines and circuits; various heat treatment pipelines; and various industrial gas and heat pipelines. The valve body of the fully welded ball valve is assembled and welded from a seamless steel pipe shell, resulting in a compact structure and a unified design. The fully welded ball valve transports flammable and explosive media such as gas and oil. Direct-buried fully welded gas ball valves can be directly buried underground, requiring only a small shallow well on the surface, greatly saving construction costs and project time. Fully welded ball valves have strong adaptability to pressure and temperature changes and will not produce any leakage within the specified pressure and temperature range.

The Shenhua Coal Liquefaction Project is a major undertaking for China’s petroleum substitution strategy and independent innovation. Central leaders attach great importance to it, requiring all relevant departments and units to prioritize the overall situation, strengthen coordination, cooperate closely, and go all out to actively support Shenhua Group in its commissioning work. The coal liquefaction and gasification units utilize a large number of imported wear-resistant ball valves, which are expensive and have slow delivery cycles. Chaoda Valves possesses leading domestic R&D and manufacturing capabilities in hard-seal ball valves and wear-resistant ball valves. Chaoda has undertaken the task of localizing the production of wear-resistant ball valves for the Shenhua Coal Liquefaction Project, and some products are already in use in the equipment, thus achieving localization of wear-resistant ball valves and shortening delivery times.

The API monogram is the product logo of the American Petroleum Institute, established in 1924. Its purpose is to certify equipment and materials produced and to identify manufacturers that meet API quality systems and product standards. 6FA is a fire resistance certification specifically for the fire resistance testing of valves according to the 6A standard. API 6FA sets the testing requirements and performance evaluation criteria for API 6A pressure vessels and API 6D valves exposed to flame. The performance requirements of API SPEC 6FA-1999 establish acceptable standard limits regardless of specification or pressure class. The fire resistance performance of a ball valve refers to its ability to maintain normal operation in a high-temperature flame. The fire resistance performance of a ball valve is a crucial indicator of its safety performance. Fire resistance testing is the only method to determine its fire resistance performance. Ball valves used on offshore platforms and in gas fields are required to undergo fire resistance testing. The fire resistance testing apparatus consists of a burner (capable of burning natural gas), a fire-resistant combustion chamber, and a leak detection system.
