April 7 marked the 16th Sinopec Corporate Quality Day, themed "Pursue Excellent Quality, Empower Secondary Business Expansion". Aligned with the corporate theme, all branches under Sinopec Hunan Oil Products Company launched coordinated cross-regional quality-themed campaigns. The firm fulfilled its social commitment of "Every Drop of Oil Is a Promise" and publicly demonstrated end-to-end refined fuel quality supervision outcomes to the public.
During the quality day campaign, all municipal subsidiaries simultaneously hosted public open days and fuel science popularization events. Government regulatory officials, corporate cooperative clients and local residents were invited to visit oil depots and service stations to observe the full fuel quality management workflow on site. Specifically, Sinopec Changde, Yongzhou, Zhangjiajie, Hengyang, Xiangtan, Yueyang and Loudi Oil Products Branch held open days at regional oil depots. Guests toured oil loading zones and central quality testing laboratories, witnessing real-time fuel sampling inspection and metrological verification procedures.
Sinopec subsidiaries in Zhangjiajie, Hengyang, Xiangtan, Yueyang and Loudi built customer trust through hands-on equipment operation, immersive scenario experience and targeted quality science lectures. Professional staff resolved public inquiries about fuel composition standards and fuel metrological supervision one-on-one. Changde Oil Products Branch showcased the working logic of high-precision mass flowmeters with a measurement accuracy of 0.1% and demonstrated automated outbound fuel supervision systems. Yongzhou Oil Products Branch operated professional fuel testing instruments live, explained sulfur content limits of China National VI B standard gasoline, and clarified internal management rules: every fuel batch must pass laboratory tests, and unqualified fuel is strictly banned from warehouse inbound and outbound procedures.
For offline retail scenarios, Sinopec Changsha, Shaoyang, Zhuzhou, Xiangxi, Chenzhou and Huaihua Oil Products Branches set up dedicated consulting booths at core highway and urban service stations. Staff conducted visual comparison of qualified and adulterated fuel samples and distributed popular science brochures to teach consumers the official three-step fuel identification method: smell check, visual check and dip test. On-site teams also displayed official verification seals and metrological certification documents of fuel dispensers, and demonstrated routine dispenser self-inspection and fuel density testing processes, making Sinopec’s quality supervision measures transparent and verifiable for end consumers.
Sinopec Hunan Oil Products Company adheres to Sinopec’s core guideline of "Quality Always Takes the Lead" and regards fuel quality control as the bottom line of daily operation. The company integrates laboratory inspection, digital technological empowerment and standardized management system optimization to enforce rigid full-lifecycle quality supervision. In 2025, the firm completed 7,638 inbound fuel batch inspections, 8,432 routine random inspections at depots and stations, and 428 random sampling tests conducted by government regulators and internal audit teams. All tested batches achieved a 100% pass rate.
Routine special inspections on fuel dispenser accuracy and volumetric meter calibration for oil depots are implemented monthly. Three key operational indicators across Hunan province maintained full compliance: 100% pass rate for mandatory dispenser metrological verification, 100% compliance of seal management, and 100% pass rate for daily fuel random inspections.
Another core quality milestone is that Sinopec Hunan Oil Products Company Central Laboratory obtained official accreditation from the China National Accreditation Service for Conformity Assessment (CNAS). The national-level authoritative qualification validates independent fuel testing capabilities, providing stable technical support for unified provincial fuel quality risk prevention.
In terms of technological innovation and digital transformation, the company upgraded quality inspection efficiency via intelligent monitoring tools. Its independently developed Combined Testing Device for Micro Distillation Range and Closed Flash Point passed official project acceptance. This technology is the world’s first integrated testing solution, with 3 national invention patents filed. Compared with mainstream domestic testing equipment, the device delivers dramatically improved data stability and accuracy for distillation range detection, shortening fuel quality testing cycles significantly. Besides, the company widely promoted automatic calibration technology for horizontal storage tank volume tables, cutting manual metrological workload and improving depot measurement efficiency by over 30%.
For management system and talent team building, Sinopec Hunan Oil Products Company continuously optimizes the ISO9000 quality management system, revises detailed operational quality guidelines and clarifies individual quality accountability for every post in storage, transportation and retail links. The company leverages annual key public nodes including March 15 Consumer Rights Day, April 7 Corporate Quality Day, May 20 Metrology Day and National Quality Month to host quality skill competitions, safety and quality emergency drills and public science campaigns, fostering a company-wide quality-oriented corporate culture.
In 2025, 20 special training sessions for metrology and quality inspection were organized, covering 400 frontline laboratory and metrological staff. The standardized talent training mechanism guarantees long-term, stable full-process fuel quality control for retail customers, industrial bulk fuel buyers and government cooperative projects across Hunan Province.
