The valve maintenance project of Shandong Yellow River New Materials – 150,000 tons/year lubricant base oil hydrotreating combined unit at Nether Seal’s manufacturing center in Shanghai, China, not only marked the official launch of Nether Seal’s manufacturing center in Shanghai, China, but also demonstrated our relentless pursuit of quality and service excellence.

Upon receiving the valves, our maintenance engineers promptly conducted meticulous inspections and assessments of wear, tear and faults. Collaborating with the Technology Innovation Center, we devised a scientific and rigorous repair plan, precisely listing the valve parts need to be replaced. With careful planning, we ensured the repair work was both high-quality and efficient.

At the repair site, our workers strictly implement production and quality procedures, meticulously attending to every detail. From pre-preparation to assembly and adjustment, each stage was supervised by dedicated personnel, with clear and detailed instructions for key points and rigorous quality control measures. This ensured the precision and accuracy in every step, laying a solid foundation for the high quality of our products.

For the valve parts provided by suppliers, we uphold the principle of “quality first” and implement a strict quality inspection system. Every batch of incoming parts undergoes rigorous quality checks, and any substandard products are rejected outright. This ensures that the repaired valves can withstand the test of time and environmental factors, guarding the safety and stability of production lines.

Through repeated adjustment and optimization, we relentlessly pursued excellent sealing performance. Multi-dimensional validations, including low-pressure gas seal tests, high-pressure water seal tests, and shell strength tests, were conducted strictly in accordance with the latest international standards and customer requirements. Ultimately, we achieved remarkable results, ensuring that the valves’ sealing properties and durability reached industry-leading levels. It is our precise control to every detail that can ultimately achieve high-quality products and satisfied customers.

With the successful conclusion of the valve repair project for Shandong Yellow River New Materials, this is not only a significant step towards precise, meticulous, and standardized production forward for our maintenance team, but also a bright signal of the official launch of Nether Seal China Shanghai Manufacturing Center. Acknowledging that every success stems from the trust and support of our customers, we pledge to continue upholding the “customer-centered” service philosophy, continuously improving service quality, ensuring timely delivery of excellent products, and creating greater value for our clients.

Nether Seal, with practical actions, embodies our relentless pursuit and commitment to excellence, marching towards an even more brilliant future.
