2025/04 – Nether Seal Successfully Obtains Special Equipment Type Test Certificate

In April 2025, Nether Seal’s RSBV products successfully passed the rigorous tests of special equipment type testing and secured the Special Equipment Type Test Certificate approved and issued by the Shanghai Special Equipment Supervision and Inspection Technical Research Institute. This achievement not only underscores Nether Seal’s consistent commitment to technological development, meticulous product quality control, and unwavering product innovation spirit but also garners high recognition and trust from national relevant professional institutions and departments.

The Special Equipment Type Test Certificate, as a mandatory certification by the state for the safety performance of pressure pipeline components, encompasses a stringent process that includes design review, material testing, performance testing, and production system evaluation, among other aspects. Nether Seal’s attainment of this authoritative qualification undoubtedly signifies that its research and development, production, and quality management systems in the field of pressure pipeline valves for special equipment have reached industry-leading standards, further solidifying the company’s core competitiveness in high-end valve manufacturing.

During this testing, two valves produced by our company successfully withstood the challenges posed by various demanding conditions under rigorous testing by inspectors, with test results fully complying with the requirements of GB/T 19672-2021 and TSG D7002-2023. Notably, the sealing performance achieved during testing met the ISO 5208 Class A standard, demonstrating exceptional zero-leakage performance and successfully obtaining the Special Equipment Type Test Certificate (for pressure pipeline components).

The approval of this certification indicates that Nether Seal’s RSBV products meet the highest national standards in key indicators such as pressure resistance, sealing, and durability, enabling widespread application in high-risk sectors such as oil and chemicals, and providing customers with safer and more reliable fluid control solutions.

“The acquisition of this type test certificate is a testament to Nether Seal’s valve technology research and development and manufacturing capabilities,” expressed Danny, the chief application engineer of our company, with confidence. “In the future, we will continue to increase our technological R&D investment in the field of special equipment, strictly control product quality, and serve domestic and international customers with more comprehensive solutions, driving the industry towards efficiency, safety, and environmental friendliness.”

The successful completion of this valve type test not only opens up broader market business opportunities for the company and lays a solid foundation for subsequent order acquisitions but also accumulates valuable experience for future type tests of other products. Looking ahead, Nether Seal will continue to uphold its innovative spirit, leveraging high-level collaboration to drive the company towards high-quality development and create even more brilliant chapters.
