Keystone Vessel Manufacturing Co., Ltd. was established in September 2022 and is headquartered in the Economic Development Zone of Suixian County, Suizhou City, Hubei Province, China. As an enterprise specializing in the R&D and manufacturing of specialty vessels, the company currently operates a modern production base spanning over 20,000 square meters. With a workforce of 67 highly skilled professionals, it boasts an annual production capacity of 4,000 units.

The company has obtained China Special Equipment TS certification, American ASME certification, European Union TPED certification, as well as factory manufacturing permits from China Classification Society and French Bureau Veritas, mandatory safety certification issued by the U.S. Department of Transportation (DOT). It has also passed ISO 9001:2000 quality management system, environmental safety management system, and occupational health and safety management system certifications, establishing a comprehensive quality assurance system.

The company has established strategic partnerships with leading domestic and international research institutions to jointly tackle critical technological challenges. Addressing bottleneck issues in the semiconductor industry, the company has achieved breakthroughs in key preparation technologies for ultra-pure materials through sustained R&D investment. Its independently developed ultra-pure austenitic stainless steel materials now meet and surpass the purity standards of some internationally leading enterprises, resolving the reliance on imported packaging materials for electronic-grade chemicals. The products have been certified and adopted by internationally renowned semiconductor companies such as TSMC, Yangtze Memory Technologies, and Kioxia. Upholding the development philosophy of “Advancing the Nation through Technology, Strengthening the Enterprise through Research,” the company has filed over 20 invention patents and participated in drafting two national standards: “Stainless Steel Welded Cylinders” has been approved, while “Ultra-Pure Austenitic Stainless Steel Plates for Semiconductor Pressure Vessels” has secured national-level approval under the 14th Five-Year Plan.

The company's portable tank consistently hold the top global market share, with products exported to five continents. In the hazardous chemicals sector, it specializes in ISO tanks,portable tank, and high/medium/low-pressure vessels; in the biopharmaceutical industry, it provides bulk vaccine tanks and cryogenic storage containers for genetic materials; in the semiconductor industry, it offers specialty gas cylinders and ultra-high-purity bulk chemical storage and transportation vessels; in aerospace, it manufactures launch and specialized vessels. For deep-sea exploration, it provides vessels for drilling platforms and offshore equipment; and for specialized sectors like nuclear energy and power generation, it has evolved into a manufacturer with significant competitive advantages in storage and transportation equipment.

The company firmly believes in the development philosophy of “advancing the nation through technology and strengthening the enterprise through scientific research,” and has formulated a clear five-year development plan: First, achieve the top market share in China for ultra-pure vessels; Second, maintain an unshakable global leadership position in portable tank; Third, expand service capabilities in strategic fields such as viral pharmaceuticals, nuclear energy and power, deep-sea exploration, and aerospace; Fourth, establish itself as an internationally renowned benchmark enterprise in the specialty container industry, serving global customers.

In the future, Keystone Vessel will continue to deepen its expertise in the specialty vessel sector. Through continuous technological innovation and industrial upgrading, we will empower China's high-end manufacturing to overcome more technical barriers. We are committed to providing global customers with safer and more reliable storage and transportation equipment solutions, striving to become an international enterprise brand that represents the level of Chinese manufacturing.
